Email Plain Text Generator

Convert HTML email to clean plain text with one click

Why does every HTML email need a plain-text version?

Some email clients (older versions, accessibility readers, low-bandwidth networks) can't render HTML. Email standards require a multipart message with both text/html and text/plain MIME parts. Including plain text boosts deliverability and ensures your message reaches everyone.

How do I add a plain-text version in my ESP?

SendGrid: Use the Mail Send API with both "html" and "text" fields. Klaviyo: Editor → Settings → Plain text version (auto-generated, but you can edit). Mailchimp: Design → Edit → Code editor → Plain text tab. Most ESPs auto-generate plain text, but manually crafting it improves quality.

Does plain text email convert better than HTML?

No. HTML emails convert better on average. But plain text builds trust (feels more personal) and performs exceptionally well in B2B contexts. The best strategy: send HTML as primary, include plain text as fallback. Some users will read plain text by choice — don't let them miss your message.

What happens if my HTML email has no text/plain part?

Email clients will attempt to strip HTML tags and generate their own plain text version — usually with poor results. Links become raw URLs, formatting is lost, and spacing gets weird. By including a clean, manually-crafted plain text part, you control the experience and ensure consistent rendering.

Why We Built This Tool

HTML-only emails fail in clients that can't render it — older email clients, accessibility readers, low-bandwidth networks. Email standards require multipart messages with both text/html and text/plain MIME parts. Without plain text, email clients force-generate their own by stripping HTML tags — usually with poor results.

What Goes Wrong Without This

Most ESPs auto-generate plain text by removing HTML tags, but this leaves raw URLs, collapses spacing, and loses formatting. Manually-crafted plain text ensures proper formatting, readable links, and professional presentation. Email clients that read plain text by choice should get a quality experience.

Email Marketing Agencies

Ensure client emails include manually-crafted plain text versions instead of auto-generated garbage. Proper plain text improves inbox delivery and client campaign consistency.

B2B SaaS & Outbound Teams

Plain text performs exceptionally well in B2B selling and transactional contexts, signaling authenticity. Include properly formatted plain text for every outbound sequence and transactional email.

Frequently Asked Questions

What's the difference between text/html and text/plain MIME parts?
A multipart email has both versions: text/html (rendered in modern clients) and text/plain (fallback for accessibility, older clients, and users who prefer plain text). Email standards require both. Clients choose which version to display based on their capabilities.
Will plain text email hurt my open rates?
No. If properly formatted, plain text email performs just as well as HTML in B2B contexts and often sees higher engagement due to perceived authenticity. Your opens depend on subject line and sender reputation, not format. Including plain text is a deliverability win, not a conversion loss.
Should I remove images from plain text?
Yes. Plain text can't render images, so describe them with alt text instead. For critical elements (product photos, buttons), you must use HTML. For body text and formatting, plain text is sufficient. Always include alt text in your HTML — this is what shows in the plain text version.
Do I need an InboxEagle account to use this tool?
No. This tool is completely free and requires no account or sign-up. InboxEagle provides it as a standalone resource for email marketers, developers, and agencies.
