Optimizing Plain Text Versions of HTML Emails

Creating effective plain text versions of HTML emails is a critical yet often overlooked aspect of successful email marketing. Plain text alternatives ensure that your message can be delivered and understood by all recipients, regardless of their email client's capabilities. This comprehensive guide will walk you through the best practices, implementation strategies, and common pitfalls to help you optimize your plain text emails for maximum deliverability and engagement.

Why Plain Text Emails Matter

Despite the prevalence of HTML emails, plain text versions remain essential for several reasons:

• Compatibility: Not all email clients support HTML formatting, so a plain text alternative ensures your message can be read by everyone.
• Deliverability: A properly built multipart email with a matching plain text part looks like legitimate mail. HTML-only messages, or ones with an empty or mismatched text part, can add points in spam filters such as SpamAssassin.
• User preference: Some users simply prefer plain text emails, either for accessibility reasons or personal choice.

Best Practices for Plain Text Emails

Keep it concise and scannable

Plain text emails should be concise and easy to scan. Use short paragraphs, bullet points, and clear headings to break up the content and make it more digestible.

Maintain a clear hierarchy

Even without HTML formatting, you can create a clear hierarchy in your plain text emails using capitalization, white space, and special characters. For example:

==== Main Heading ====

-- Subheading --

* Bullet point 1
* Bullet point 2

Include a plain text call-to-action

While you can't use HTML buttons in plain text emails, you can still include a clear call-to-action by providing a full URL. Use a clean link on your own domain (or your branded tracking domain) rather than a public URL shortener, which spam filters treat with suspicion.

Optimize for readability

Plain text emails should be easy to read and understand. Use simple language, avoid jargon, and aim for a 8th-grade reading level. You can use online tools like the Hemingway App to assess your email's readability.

Implementing Plain Text Emails

Most email marketing platforms allow you to create a plain text version of your HTML email. Here's a step-by-step guide for implementing plain text emails in your campaigns:

1. Compose your HTML email as usual
2. Look for the plain text editor in your email platform (often a "Plain-text" tab or option)
3. Copy and paste your HTML email content into the plain text editor
4. Remove all HTML tags and formatting
5. Optimize the plain text content using the best practices outlined above
6. Test your plain text email to ensure it renders correctly and is easy to read

Automating plain text creation

Some email platforms offer tools to automatically generate a plain text version of your HTML email. While these tools can save time, it's essential to review and optimize the generated plain text to ensure it meets best practices and accurately conveys your message.

Troubleshooting Common Issues

Even with careful optimization, plain text emails can sometimes encounter issues. Here are some common problems and how to troubleshoot them:

Measuring Success

Because the plain text version travels in the same message as the HTML, you usually can't measure it separately, and opens can't be tracked in plain text because there's no tracking pixel. If you send plain-text-only campaigns, or test plain text against HTML, track metrics such as:

• Click-through rates
• Conversion rates
• Unsubscribe rates

Compare these metrics to your HTML email performance to identify areas for improvement. You can also A/B test different plain text versions to optimize your content and layout.

Advanced Strategies

Once you've mastered the basics of plain text email optimization, consider these advanced strategies to take your campaigns to the next level:

Personalization

Use merge tags to personalize your plain text emails with the recipient's name, location, or other relevant information. This can help increase engagement and make your messages feel more targeted.

Dynamic content

Some email platforms allow you to create dynamic plain text content based on subscriber data or preferences. This enables you to tailor your messages to specific segments of your audience for better results.

Accessibility

Plain text emails are inherently more accessible than HTML emails, but there are still steps you can take to improve their usability for people with disabilities. For example:

• Put a short description before each URL so readers know where it leads (e.g., "View your order: https://...")
• If your HTML email relies on images to carry information, write that information out in the plain text version
• Use clear, concise language and avoid complex jargon
