Email deliverability tips

Email marketing is a powerful tool for businesses to connect with their audience. It’s cost-effective, scalable, and can deliver impressive ROI when executed correctly. However, getting your emails into the inbox and not the dreaded spam folder is a constant challenge.

To improve your email deliverability and make the most of your email marketing efforts, follow these 26 dos and don’ts across various aspects of your email campaigns.

 

Use Double Opt-In

Do you want engaged subscribers who genuinely want to receive your emails? The double opt-in process is your answer. It’s a simple yet powerful way to ensure that your subscribers are not only interested but also willing to engage with your content.

How Double Opt-In Works:

• Subscriber Signs Up: A user expresses interest in your emails by signing up through your website or another channel.
• Confirmation Email: After sign-up, the user receives a confirmation email requesting them to verify their subscription. This typically includes a link or button labeled “Confirm” or “Subscribe.”
• Subscriber Confirms: To complete the subscription process, the user clicks the confirmation link/button, verifying their intent to receive emails from you.

Why Double Opt-In Matters:

• Reduces Spam Complaints: Since subscribers have to take an additional step to confirm, you’re less likely to end up in their spam folder due to unwanted emails.
• Improved Engagement: Subscribers who confirm their subscription are more likely to engage with your emails, resulting in higher open and click-through rates.
• Enhanced Sender Reputation: Email service providers (ESPs) view double opt-in as a sign of responsible email marketing, which can positively impact your sender reputation.

 

Segment Your List

Sending the same message to your entire email list may seem efficient, but it can actually harm your email deliverability. Email segmentation involves dividing your list into smaller, targeted groups based on specific criteria.

Benefits of Segmentation:

• Relevant Content: Segmented lists allow you to tailor your content to the interests and preferences of each group. This means your emails are more likely to resonate with recipients.
• Improved Engagement: Targeted emails tend to have higher open and click-through rates, as they speak directly to the needs of the recipients.
• Reduced Unsubscribes: When subscribers receive content that aligns with their interests, they’re less likely to unsubscribe from your list.

Segmentation Ideas:

• Demographics: Consider factors like age, gender, location, and job title to create segments.
• Behavior: Segment based on past purchase behavior, website visits, or email engagement.
• Email Preferences: Allow subscribers to select the type of content they want to receive during the sign-up process.

 

Regularly Clean Your List

A clean email list is essential for maintaining a healthy sender reputation and ensuring your emails reach the intended inboxes. Over time, email lists can become cluttered with invalid or disengaged subscribers.

Clean-Up Strategies:

• Remove Inactive Subscribers: Identify and remove subscribers who haven’t engaged with your emails over an extended period. These subscribers are unlikely to suddenly become active.
• Check for Invalid Addresses: Regularly scan your list for email addresses that bounce consistently. Remove these addresses to improve deliverability.
• Monitor Complaints: Keep an eye on spam complaints. If you receive multiple complaints about your emails, investigate the issue and take corrective action.
• Set a Re-Engagement Campaign: For disengaged subscribers, send a re-engagement campaign to gauge their interest. If they still don’t respond, consider removing them from your list.

Benefits of List Cleaning:

• Higher Open Rates: With a clean list, your open rates are likely to improve since you’re sending to a more engaged audience.
• Cost Savings: You’ll save money by not paying for subscribers who aren’t interested in your emails.
• Better Sender Reputation: ESPs favor senders with clean lists, leading to better email deliverability.

 

Update Contact Information

Maintaining accurate contact information for your subscribers is crucial for ensuring your emails reach their intended recipients. People change jobs, switch email providers, or update their contact details, and failing to keep up can result in delivery issues.

Updating Strategies:

• Encourage Subscribers to Update: Include a call to action in your emails, encouraging subscribers to update their contact information if it has changed.
• Offer a Preference Center: Create a preference center where subscribers can easily update their email address or other contact details.
• Regularly Validate Data: Use email validation tools to check the validity of email addresses in your list and update or remove any that are no longer valid.

Benefits of Updated Contact Information:

• Reduced Bounce Rates: Accurate contact information means fewer bounced emails, which can negatively impact deliverability.
• Continued Engagement: You can maintain a connection with your audience, even if they change their contact details.
• Improved Tracking: Accurate data allows you to track engagement more effectively and make data-driven decisions.

 

Respect Unsubscribe Requests

While it might seem counterintuitive, respecting unsubscribe requests is essential for maintaining a positive sender reputation and improving email deliverability. Unsubscribes are a natural part of email marketing, and handling them properly is a sign of professionalism.

Compliance with Regulations:

• CAN-SPAM Act (U.S.): The CAN-SPAM Act mandates that you honor unsubscribe requests promptly and without delay. Failing to do so can result in penalties.
• GDPR (European Union): The General Data Protection Regulation also requires honoring unsubscribe requests and offers additional data protection measures.

Best Practices for Unsubscribes:

• Easy Unsubscribe Process: Make it simple for subscribers to unsubscribe by including an unsubscribe link in every email.
• Prompt Removal: Remove unsubscribed users from your list immediately. This helps you avoid accidentally sending them emails in the future.
• Confirmation: Send a confirmation email to ensure that the unsubscribe request was intentional. This can help prevent accidental unsubscribes.

Benefits of Respecting Unsubscribe Requests:

• Compliance: You remain compliant with email marketing regulations, avoiding legal issues.
• Positive Sender Reputation: ESPs view honoring unsubscribe requests as a sign of responsible email marketing.
• Focus on Engaged Subscribers: By removing disinterested subscribers, you can concentrate on nurturing and engaging your active audience.

 

Don’t Buy Email Lists

One of the cardinal sins in email marketing is buying email lists. The temptation to quickly amass a large list of potential recipients can be alluring, but the consequences of this practice can be severe.

Why You Should Avoid Buying Email Lists:

• High Bounce Rates: Purchased lists often contain outdated or invalid email addresses, leading to high bounce rates that can damage your sender reputation.
• Increased Spam Complaints: Recipients on bought lists did not explicitly opt in to receive emails from you, making them more likely to mark your emails as spam.
• Potential Legal Consequences: Depending on your location and the regulations you’re subject to, buying email lists may be illegal and result in fines or legal action.
• Damaged Reputation: Sending unsolicited emails harms your sender reputation, making it difficult to reach legitimate subscribers.

 

Don’t Neglect Permission

Permission is the cornerstone of ethical and effective email marketing. It’s essential to obtain explicit consent from individuals before adding them to your email list.

Why Permission Matters:

• Engaged Subscribers: Subscribers who have given their consent are more likely to engage with your emails, resulting in higher open and click-through rates.
• Compliance with Regulations: Many countries have email marketing regulations, such as the CAN-SPAM Act in the United States and GDPR in Europe, which require permission-based email marketing.
• Better Sender Reputation: ESPs view sending emails to permission-based lists as a sign of responsible email marketing, which can positively impact your sender reputation.
• Respect and Trust: Obtaining permission demonstrates respect for your audience’s preferences and fosters trust between your brand and your subscribers.

 

Don’t Overload Subscribers

Email overload is a common complaint among email recipients. Bombarding your subscribers with too many emails in a short span can lead to subscriber fatigue and negatively impact your email deliverability.

Why Overloading Subscribers is Detrimental:

• Increased Unsubscribes: Overloaded subscribers are more likely to hit the unsubscribe button, leading to list attrition.
• Spam Complaints: Frustrated recipients may mark your emails as spam, tarnishing your sender reputation.
• Lower Engagement: Too many emails can overwhelm recipients, causing them to ignore or delete your messages without reading them.

Best Practices for Email Frequency:

• Set Expectations: Inform subscribers about your email frequency during the sign-up process to manage their expectations.
• Segment Your List: Segmenting your list allows you to send relevant content to specific groups, reducing the need for frequent emails to everyone.
• Monitor Engagement: Pay attention to open and click-through rates to gauge subscriber engagement. Adjust your email frequency based on these metrics.

 

Personalize Subject Lines

Your email subject line is the first thing recipients see, and it plays a crucial role in whether your email gets opened or ignored. Personalizing subject lines can significantly improve your open rates.

The Power of Personalization:

• Higher Open Rates: Emails with personalized subject lines are more likely to catch the recipient’s eye and lead to higher open rates.
• Increased Relevance: Personalized subject lines can convey that the email is tailored to the recipient’s interests or needs.
• Improved Engagement: When recipients feel that an email speaks directly to them, they are more likely to engage with the content.
• Enhanced Relationship: Personalization demonstrates that you know and care about your subscribers, fostering a stronger connection with your audience.

 

Keep It Concise

In the age of information overload, brevity is a virtue. Long-winded emails can overwhelm recipients and lead to them skipping or deleting your messages.

The Benefits of Concise Email Content:

• Improved Readability: Short, to-the-point emails are easier to read and digest, especially on mobile devices.
• Higher Engagement: Recipients are more likely to engage with emails that get to the point quickly and provide value without excessive fluff.
• Clearer Call to Action (CTA): Concise emails make it easier for recipients to understand the desired action, leading to higher click-through rates.
• Reduced Risk of Spam Filters: Excessively long emails may trigger spam filters, reducing the chances of your email reaching the inbox.

 

A/B Test Subject Lines

Your email subject lines are your first opportunity to capture your recipients’ attention. A/B testing subject lines allows you to optimize your messaging and increase open rates.

Why A/B Testing Matters:

• Data-Driven Decisions: A/B testing provides valuable insights into what resonates with your audience, enabling you to refine your approach.
• Improved Open Rates: By experimenting with different subject lines, you can identify the ones that generate the highest open rates.
• Better Engagement: Subject lines that pique recipients’ curiosity or align with their interests tend to lead to higher engagement.
• Continuous Optimization: A/B testing is an ongoing process that allows you to adapt to changing recipient preferences and behaviors.

Best Practices for A/B Testing:

• Test One Element at a Time: Focus on testing one variable at a time, such as wording, length, or personalization.
• Segment Your Tests: Segment your audience and tailor subject line tests to specific groups to achieve more targeted results.
• Analyze Results: Carefully analyze the data from your tests and use the insights to inform future subject line choices.

 

Create a Sense of Urgency

Incorporating a sense of urgency in your email subject lines and content can motivate recipients to take action promptly.

The Power of Urgency:

• Higher Conversion Rates: Urgent language can drive recipients to act quickly, leading to higher conversion rates.
• Reduced Procrastination: Creating a sense of urgency can prevent recipients from putting off action until later, increasing the likelihood of engagement.
• FOMO (Fear of Missing Out): Urgency implies that there’s something valuable or time-sensitive in your email, encouraging recipients not to miss out.
• Clear Call to Action: Urgent messages often have a more explicit call to action, making it easier for recipients to know what to do next.

Best Practices for Creating Urgency:

• Use Time-Related Language: Include phrases like “limited time offer,” “ending soon,” or “today only” to convey urgency.
• Highlight Scarcity: Mention limited quantities or availability to emphasize the urgency of taking action.
• Avoid Overuse: While urgency is effective, don’t use it excessively, as it can lose its impact over time.

 

Don’t Use All Caps

Subject lines or email content written in all capital letters can be seen as shouting and often trigger spam filters.

Why to Avoid All Caps:

• Higher Spam Risk: Emails in all caps are a common characteristic of spam, and using them can increase the chances of your email being marked as such.
• Poor User Experience: Writing in all caps can be difficult to read and may deter recipients from engaging with your content.
• Lower Credibility: All caps can make your emails appear less professional, potentially diminishing the trust recipients have in your brand.

Alternative Strategies:

• Use Capitalization Sparingly: Instead of writing entire sentences or subject lines in all caps, use capitalization for emphasis on specific words or phrases.
• Incorporate Proper Punctuation: Proper use of punctuation and sentence structure can help convey your message effectively without resorting to all caps.

 

Don’t Exaggerate or Mislead

While it’s important to grab your recipients’ attention, exaggerating or misleading them in your subject lines or email content can lead to negative consequences.

Why to Avoid Exaggeration and Misleading Content:

• Increased Spam Complaints: Exaggerated claims or misleading content can lead to recipients marking your emails as spam.
• Loss of Trust: Misleading recipients can damage the trust between your brand and your audience, making it harder to build lasting relationships.
• Long-Term Reputation Damage: Consistently sending exaggerated or misleading content can harm your sender reputation, impacting future deliverability.

Honesty and Transparency:

• Provide Accurate Information: Ensure that the content of your emails accurately reflects what recipients can expect when they open them.
• Avoid Clickbait: While it’s okay to craft compelling subject lines, avoid resorting to clickbait tactics that don’t deliver on their promises.

 

Don’t Overuse Punctuation and Symbols

Overloading your subject lines or email content with excessive punctuation marks and symbols can trigger spam filters and deter recipients.

Why to Avoid Overusing Punctuation and Symbols:

• Increased Spam Risk: Spam filters may flag emails with an abundance of punctuation and symbols as potential spam.
• Poor User Experience: Excessive punctuation and symbols can make your content appear unprofessional and disrupt the reading experience.
• Reduced Clarity: Too many symbols can obscure your message and make it challenging for recipients to understand your intent.

Balanced Use of Punctuation and Symbols:

• Use Sparingly: Incorporate punctuation and symbols judiciously to enhance the clarity and impact of your message.
• Focus on Readability: Ensure that your content remains easy to read and understand, even with the use of punctuation and symbols.

 

Mobile Responsiveness

With the majority of email opens happening on mobile devices, ensuring that your emails are mobile-responsive is no longer optional—it’s a necessity.

Why Mobile Responsiveness Matters:

• Improved User Experience: Mobile-responsive emails adapt to different screen sizes, providing recipients with a seamless and visually pleasing experience.
• Higher Engagement: Emails that look good and function well on mobile devices are more likely to be read and acted upon.
• Reduced Unsubscribes: Frustration caused by non-responsive emails can lead to higher unsubscribe rates.
• Enhanced Reputation: Email service providers (ESPs) consider mobile responsiveness a positive signal, which can improve your sender reputation.

Best Practices for Mobile Responsiveness:

• Use Responsive Design: Create emails using responsive email templates that automatically adjust to various screen sizes.
• Optimize Images: Ensure that images are appropriately sized and compressed to load quickly on mobile devices.
• Test on Mobile: Always preview and test your emails on different mobile devices and email clients to guarantee a smooth user experience.

 

Consistent Branding

Maintaining consistent branding in your email campaigns is crucial for establishing trust and recognition with your audience.

Why Consistent Branding Matters:

• Recognition: Consistent branding elements, such as logos, colors, and fonts, help recipients instantly recognize your emails.
• Trust Building: A cohesive brand identity fosters trust, making recipients more likely to engage with your content.
• Professionalism: Inconsistent branding can make your emails appear unprofessional and disjointed.

Best Practices for Consistent Branding:

• Use Brand Guidelines: Develop and follow brand guidelines to ensure consistency in all aspects of your email campaigns.
• Design Templates: Create email templates that incorporate your brand elements, making it easy to maintain consistency.
• Audit Regularly: Periodically review your emails to ensure that they align with your brand guidelines.

 

Clear Call to Action (CTA)

A clear and compelling call to action (CTA) is the linchpin of successful email campaigns. It guides recipients on the desired action and increases engagement.

Why a Clear CTA Matters:

• Higher Click-Through Rates: A well-defined CTA makes it clear what action you want recipients to take, leading to higher click-through rates.
• Improved Conversions: When recipients understand what’s expected of them, they are more likely to convert, whether it’s making a purchase or signing up for an event.
• Reduced Confusion: A clear CTA minimizes confusion and frustration, ensuring that recipients know precisely what to do next.

Best Practices for CTAs:

• Be Specific: Use action-oriented language that leaves no room for ambiguity. For example, “Shop Now” or “Subscribe Today.”
• Make It Stand Out: Use contrasting colors, larger fonts, or buttons to make the CTA visually distinct.
• Limit Choices: Keep the number of CTAs in an email to a minimum to avoid overwhelming recipients.

 

Test Across Email Clients

Email clients vary widely in how they render emails, so it’s crucial to test your emails across different clients to ensure they display correctly.

Why Testing Across Email Clients Matters:

• Consistent Display: Testing helps ensure that your emails look and function as intended, regardless of the recipient’s email client or device.
• Better User Experience: Emails that display correctly on all clients provide a positive user experience, which can lead to increased engagement.
• Avoiding Errors: Testing helps identify and rectify any issues, such as broken links or formatting problems, before sending the email.

Best Practices for Testing:

• Use Email Testing Tools: Leverage email testing tools and services to simulate how your emails will appear in various email clients.
• Preview on Real Devices: Whenever possible, preview your emails on actual devices, including mobile phones and tablets.
• Test Regularly: Test emails with each campaign, especially if you make design or template changes.

 

Don’t Use Excessive Images

While images can enhance the visual appeal of your emails, overusing them can negatively impact deliverability and user experience.

Why to Avoid Excessive Images:

• Slower Loading Times: Emails with too many images may take longer to load, potentially causing recipients to lose interest or abandon the email.
• Spam Filters: Emails that consist mostly of images can trigger spam filters, leading to lower deliverability rates.
• Accessibility: Images can pose accessibility challenges for recipients who use screen readers or have images disabled.

Balanced Use of Images:

• Complement with Text: Use a mix of text and images to convey your message. Ensure that the email makes sense even when images are disabled.
• Optimize Images: Compress and optimize images to reduce their file size, which can improve loading times.
• Test with Images Disabled: Preview your emails with images disabled to ensure they still make sense and provide value.

 

Don’t Neglect Plain Text Version

While HTML emails with images and formatting are visually appealing, it’s vital not to neglect the plain text version of your emails.

Why Plain Text Versions Matter:

• Accessibility: Plain text emails are accessible to all recipients, including those who use screen readers or have images disabled.
• Spam Filter Avoidance: Some spam filters may flag emails without a plain text version as potential spam, affecting deliverability.
• Alternative for Recipients: Plain text versions serve as an alternative for recipients who prefer a simpler format or have email clients that don’t render HTML well.

Best Practices for Plain Text Versions:

• Create a Text-Only Version: Always create a plain text version alongside your HTML email.
• Maintain Message Consistency: Ensure that the content in your plain text version matches the content and intent of the HTML email.
• Include Links: If your HTML email contains links, replicate them in the plain text version using full URLs.

 

Don’t Overcomplicate Design

While a visually appealing design can capture attention, overcomplicating your email design can lead to problems with rendering and engagement.

Why Simple Design Matters:

• Rendering Consistency: Complex designs may not render correctly on all email clients and devices, leading to a poor user experience.
• Load Times: Elaborate designs with many images and elements can slow down email load times, potentially causing recipients to lose interest.
• Clarity: A cluttered design can distract from your message, making it less clear to recipients.

Best Practices for Design Simplicity:

• Prioritize Mobile Responsiveness: Ensure your design is responsive and adapts well to mobile devices.
• Use Minimal Images: Limit the number of images and their file sizes to improve load times and avoid triggering spam filters.
• Clean Layout: Organize your content in a clean and organized layout with clear headings and sections.

 

Provide Valuable Content

Email marketing success hinges on providing value to your subscribers. Delivering valuable content keeps recipients engaged and interested in your emails.

Why Valuable Content Matters:

• Higher Engagement: Valuable content leads to higher open and click-through rates, indicating that recipients find your emails relevant and useful.
• Retention: Providing value encourages subscribers to stay on your list, reducing unsubscribe rates.
• Positive Perception: Valuable content enhances your brand’s reputation and positions you as an authority or helpful resource.

Best Practices for Valuable Content:

• Know Your Audience: Understand your audience’s needs and preferences to create content that resonates with them.
• Educational and Informative: Share knowledge, tips, and insights that can benefit your subscribers.
• Solve Problems: Address common pain points or challenges your audience faces in your content.

 

Personalize Content

Personalization goes beyond using a recipient’s name in the salutation. It involves tailoring the entire email content to the individual recipient’s preferences and behavior.

Why Personalization Matters:

• Higher Engagement: Personalized emails are more relevant to recipients, leading to higher open and click-through rates.
• Improved Conversions: Content that aligns with a recipient’s interests and behavior is more likely to convert.
• Stronger Relationships: Personalization demonstrates that you know and care about your subscribers, strengthening your relationship with them.

Best Practices for Personalization:

• Use Dynamic Content: Incorporate dynamic content that changes based on recipient data, such as past purchases or browsing history.
• Segment Your List: Divide your email list into segments based on factors like demographics, behavior, or preferences to deliver more relevant content.
• Personalize Subject Lines: Customize subject lines with recipient-specific information or interests.

 

Optimize for Readability

Emails that are easy to read and scan are more likely to be consumed and acted upon by recipients.

Why Readability Matters:

• Increased Engagement: Emails that are easy to read encourage recipients to engage with your content.
• Reduced Bounces: Improved readability can reduce bounce rates, as recipients are more likely to open and engage with your emails.
• Positive User Experience: A pleasant reading experience enhances the perception of your brand.

Best Practices for Readability:

• Use Clear Headings: Organize your content with clear headings and subheadings to guide readers.
• Bullet Points and Lists: Use bullet points and numbered lists to break up text and make information more digestible.
• Concise Paragraphs: Keep paragraphs short and to the point, with a single idea in each paragraph.

 

Maintain a Consistent Schedule

Consistency is key in email marketing. Establishing a regular sending schedule helps your subscribers anticipate and look forward to your emails.

Why Consistency Matters:

• Anticipated Content: A consistent schedule creates anticipation, encouraging recipients to open and engage with your emails.
• Avoiding Spam Filters: Erratic sending patterns can trigger spam filters, leading to deliverability issues.
• Subscriber Retention: A reliable schedule keeps subscribers on your list, reducing churn rates.

Best Practices for Consistency:

• Set a Schedule: Determine how often you’ll send emails, whether it’s weekly, biweekly, or monthly, and stick to it.
• Inform Subscribers: Communicate your sending schedule to subscribers during the sign-up process or through a welcome email.
• Monitor Engagement: Pay attention to open and click-through rates to gauge how well your schedule aligns with subscriber behavior.

 

Don’t Use Spammy Language

Using spammy language or tactics in your emails can lead to spam complaints and negatively impact your deliverability.

Why to Avoid Spammy Language:

• Avoid Spam Filters: Spam filters are designed to identify and block emails that use spammy language or tactics.
• Protect Sender Reputation: High spam complaint rates can damage your sender reputation, affecting future email delivery.
• Negative Subscriber Experience: Recipients may mark your emails as spam or unsubscribe if they perceive them as spammy.

Best Practices to Avoid Spammy Language:

• Avoid Exaggeration: Refrain from making unrealistic claims or promises in your subject lines and content.
• Avoid Excessive Punctuation: Excessive use of exclamation points or all capital letters can trigger spam filters.
• Be Transparent: Clearly identify the sender and provide a way for recipients to unsubscribe.

 

Don’t Neglect Testing

Testing your emails before sending them to your entire list is crucial for ensuring they render correctly and function as intended.

Why Testing Matters:

• Optimize User Experience: Testing ensures that your emails look good and function correctly on different devices and email clients.
• Avoid Errors: Testing helps catch issues such as broken links or missing images before they reach your audience.
• Improve Engagement: A well-tested email that renders correctly is more likely to engage recipients.

Best Practices for Testing:

• Use Email Testing Tools: Employ email testing tools and services to preview how your emails will appear on various email clients and devices.
• Test Links: Verify that all links in your email work correctly and direct recipients to the intended landing pages.
• Preview on Multiple Devices: Test your emails on different devices, including mobile phones and tablets, to ensure a consistent experience.

 

Don’t Send Generic Content

Personalized and relevant content is more likely to engage recipients than generic, one-size-fits-all messaging.

Why Personalization Matters:

• Higher Engagement: Personalized content resonates better with recipients, leading to higher open and click-through rates.
• Improved Conversions: Relevant content increases the chances of recipients taking desired actions.
• Stronger Customer Relationships: Personalization demonstrates that you understand and cater to your subscribers’ individual interests and needs.

Best Practices for Personalization:

• Segment Your List: Divide your email list into segments based on demographics, behavior, or preferences to deliver more relevant content.
• Use Dynamic Content: Incorporate dynamic content that changes based on recipient data, such as past purchases or browsing history.
• Personalize Subject Lines: Customize subject lines with recipient-specific information or interests.

 

Optimize Images

Images can enhance the visual appeal of your emails, but it’s essential to optimize them for better performance.

Why Image Optimization Matters:

• Faster Load Times: Optimized images load quickly, preventing recipients from losing interest while waiting for your email to load.
• Avoid Spam Filters: Large or unoptimized images can trigger spam filters or increase email file size, leading to deliverability issues.
• Enhanced User Experience: A balance of images and text creates a visually appealing and engaging email.

Best Practices for Image Optimization:

• Use Compressed Images: Compress images to reduce their file size without compromising quality.
• Provide Alt Text: Include descriptive alt text for images to ensure that recipients understand the content even if images are disabled.
• Balance Text and Images: Use a mix of text and images to create a well-balanced and engaging email.

 

Use Alt Text

Including alt text (alternative text) for images is an essential accessibility and email marketing best practice. Alt text provides a text description of images and serves several important purposes.

Why Alt Text Matters:

• Accessibility: Alt text ensures that recipients with disabilities, including those using screen readers, can understand the content and context of images.
• Improved User Experience: When images don’t load or are blocked, alt text provides context, preventing confusion.
• Avoiding Spam Filters: Some spam filters check for the presence of alt text, making it an important element in email deliverability.

Best Practices for Using Alt Text:

• Be Descriptive: Write concise but descriptive alt text that conveys the image’s purpose and content.
• Avoid Keyword Stuffing: Use alt text to describe the image naturally, rather than cramming it with keywords.
• Test Alt Text: Verify that alt text displays correctly when images are disabled and that it provides meaningful information.

 

Balance Text and Images

While visuals are important in email marketing, it’s crucial to strike a balance between images and text to ensure a well-rounded and engaging email.

Why Balancing Text and Images Matters:

• Accessibility: Emails that rely heavily on images can be challenging for recipients who use screen readers or have images disabled.
• Faster Loading: A balance of text and images ensures that emails load quickly, preventing recipient frustration.
• Content Engagement: Including relevant text allows you to convey information effectively, even when images are blocked.

Best Practices for Balancing Text and Images:

• Use HTML Text: Whenever possible, use HTML text instead of embedding text within images.
• Provide Context: Ensure that the text in your email complements the images and provides context.
• Test with Images Disabled: Preview your emails with images disabled to assess the user experience and ensure your message is clear.

 

Don’t Send Image-Only Emails

Sending emails that consist entirely of images can be detrimental to deliverability and user experience.

Why to Avoid Image-Only Emails:

• Accessibility Issues: Image-only emails are inaccessible to recipients who use screen readers or have images disabled.
• Higher Spam Risk: Some spam filters may flag image-only emails as suspicious or spam, reducing deliverability.
• Limited Engagement: Recipients may not engage with image-only emails as effectively as emails with a balance of text and images.

Best Practices to Avoid Image-Only Emails:

• Use HTML Text: Incorporate HTML text alongside images to ensure that your message is conveyed even when images are blocked.
• Optimize Image Load Times: If using images, ensure they are optimized for quick loading to prevent recipient impatience.
• Provide Alt Text: Include alt text for all images to improve accessibility and user experience.

 

Don’t Use Large Attachments

Sending large email attachments can lead to problems with email deliverability and recipient frustration.

Why to Avoid Large Attachments:

• Delivery Issues: Large attachments can trigger spam filters and lead to email delivery problems.
• Recipient Frustration: Slow-loading emails due to large attachments can frustrate recipients and discourage engagement.
• Limited Accessibility: Some email clients or devices may struggle to handle large attachments, leading to accessibility issues.

Best Practices to Avoid Large Attachments:

• Host Files Externally: Instead of attaching large files, host them on a cloud storage service and provide a download link.
• Compress Files: Compress large files to reduce their size before sending them as attachments.
• Consider Alternatives: If possible, avoid email attachments altogether and provide links to files hosted externally.

 

Warm Up New IP Addresses

If you’re using a new IP address for email marketing, it’s crucial to warm it up gradually to establish a positive sender reputation.

Why IP Warming Matters:

• Avoid Spam Traps: A gradual warm-up helps you avoid hitting spam traps and potentially being blacklisted.
• Build Trust: Warming up your IP address gradually builds trust with internet service providers (ISPs) and email service providers (ESPs).
• Ensure Deliverability: A well-warmed IP address is more likely to have good deliverability rates, ensuring your emails reach the inbox.

Best Practices for IP Warming:

• Start Slow: Initially, send emails to a small, engaged segment of your list to gauge recipient engagement and response.
• Gradual Increase: Over time, gradually increase your sending volume as you monitor deliverability and engagement metrics.
• Maintain Quality: Throughout the warming process, prioritize sending high-quality, engaging content to maintain a positive reputation.

 

Monitor IP Reputation

The reputation of your sending IP address plays a significant role in determining whether your emails land in the inbox or spam folder.

Why Monitoring IP Reputation Matters:

• Inbox Placement: A positive IP reputation increases the likelihood that your emails will be delivered to the inbox.
• Avoid Spam Filters: Poor IP reputation can trigger spam filters, causing your emails to be marked as spam or even blocked.
• Sender Trust: A strong sender reputation builds trust with email service providers (ESPs) and internet service providers (ISPs).

Best Practices for Monitoring IP Reputation:

• Use Reputation Monitoring Tools: Utilize tools and services that provide insights into your IP reputation.
• Identify and Address Issues: Regularly monitor your IP’s performance and take corrective actions if you notice any delivery problems or reputation issues.
• Warm Up New IPs: If you acquire a new IP address, follow a gradual warm-up process to establish a positive reputation.

 

Authenticate Your Emails

Email authentication helps verify the legitimacy of your emails and ensures that they aren’t spoofed or used for phishing attacks.

Why Email Authentication Matters:

• Trustworthiness: Authentication mechanisms like SPF, DKIM, and DMARC enhance your email’s credibility and trustworthiness.
• Inbox Delivery: ESPs and ISPs favor authenticated emails, increasing the likelihood of inbox delivery.
• Security: Authentication helps protect your brand and recipients from phishing and spoofing attempts.

Best Practices for Email Authentication:

• Implement SPF: Set up Sender Policy Framework (SPF) records to specify which IP addresses are authorized to send emails on your behalf.
• Enable DKIM: Use DomainKeys Identified Mail (DKIM) to digitally sign your emails, ensuring their authenticity.
• Configure DMARC: Implement Domain-based Message Authentication, Reporting, and Conformance (DMARC) to specify how authentication failures should be handled.

 

Don’t Share IPs with Spammers

Sharing an IP address with spammers or sending bulk emails from a shared IP can negatively impact your deliverability.

Why Avoiding IP Sharing Matters:

• Reputation Damage: Sharing an IP with spammers can tarnish your IP’s reputation, causing your legitimate emails to be flagged as spam.
• Limited Control: Shared IPs may not give you full control over email sending practices, potentially exposing you to delivery issues.
• Inconsistent Reputation: You have no control over the email practices of others sharing the IP, making it challenging to maintain a positive reputation.

Best Practices to Avoid IP Sharing:

• Use Dedicated IPs: Whenever possible, use dedicated IP addresses for your email marketing campaigns to maintain control over your sender reputation.
• Choose Reputable ESPs: If you use an email service provider (ESP), select one with a strong track record of maintaining clean IP pools.
• Monitor IP Activity: Regularly monitor the sending behavior of your IP address and take action if you notice any unusual patterns.

 

Don’t Send from a Blacklisted IP

Sending emails from a blacklisted IP address is a surefire way to harm your email deliverability.

Why Avoiding Blacklisted IPs Matters:

• Blocked Delivery: Emails sent from blacklisted IPs are often blocked entirely, preventing them from reaching recipients.
• Negative Reputation Transfer: If you send from a blacklisted IP, it can negatively affect the reputation of any associated domains.
• Recovery Challenges: Recovering from a blacklisting can be time-consuming and challenging, leading to prolonged delivery problems.

Best Practices to Avoid Blacklisted IPs:

• Regularly Check Blacklists: Use blacklist monitoring tools to check whether your IPs or domains are listed on any blacklists.
• Address Issues Promptly: If you discover that your IP is blacklisted, take immediate action to identify and rectify the underlying problem.
• Implement Best Practices: Follow email marketing best practices to minimize the risk of your IPs being blacklisted in the first place.

 

Avoid Sudden IP Changes

Frequently switching IP addresses or sending large volumes of emails from a new IP without proper warm-up can trigger spam filters.

Why Avoiding Sudden IP Changes Matters:

• Suspicion by ISPs: Sudden IP changes can raise suspicion with ISPs, as it may appear like a tactic used by spammers.
• Inconsistent Reputation: Frequent IP changes can lead to an inconsistent sender reputation, making it difficult to establish trust.
• Deliverability Issues: Emails sent from new IPs may face temporary delivery problems until a positive reputation is built.

Best Practices to Avoid Sudden IP Changes:

• Plan IP Changes Carefully: If you need to change IPs, plan the transition and warm-up process thoroughly to minimize disruptions.
• Gradual Transition: Gradually increase your email sending volume from a new IP, closely monitoring deliverability and engagement metrics.
• Maintain Reputation: Continue to send emails from your existing IPs while transitioning to new ones to maintain a consistent sender reputation.

 

Conclusion

Improving email deliverability is an ongoing process that requires attention to detail and adherence to best practices.

By following these dos and don’ts, you can enhance your email marketing strategy, build trust with your subscribers, and achieve better results from your email campaigns.

Remember that maintaining a positive sender reputation is key to consistently landing in the inbox rather than the spam folder.
