title: "Should I send plain-text or HTML emails for SaaS?"
summary: "Plain text wins for founder-voice broadcasts, transactional emails, and re-engagement sequences – it looks personal and reaches the primary inbox more reliably. HTML wins for newsletters with visual content (screenshots, charts, product updates). Most indie SaaS over-design their emails. Default to plain text and add HTML only when the content genuinely needs it."

# Should I send plain-text or HTML emails for SaaS?

> Plain text wins for founder-voice broadcasts, transactional emails, and re-engagement sequences – it looks personal and reaches the primary inbox more reliably. HTML wins for newsletters with visual content (screenshots, charts, product updates). Most indie SaaS over-design their emails. Default to plain text and add HTML only when the content genuinely needs it.

## Supporting points

- Plain-text emails feel like a person; HTML emails feel like marketing. The Soap Opera Sequence and most Seinfeld emails should be plain-text.
- Gmail's tabbed inbox (Primary, Promotions, Updates) sorts HTML-heavy emails into Promotions more often. Plain text reaches Primary more reliably.
- Hybrid (text-styled HTML that looks plain) is the practical compromise. Single column, no images, hyperlinks instead of buttons.
