TL;DR
Question
Should I send plain-text or HTML emails for SaaS?
Direct answer
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.

What's the nuance?

Plain-text emails feel like a person; HTML emails feel like marketing. The Soap Opera Sequence and most Seinfeld emails should be plain-text.

What else should I know?

Gmail's tabbed inbox (Primary, Promotions, Updates) sorts HTML-heavy emails into Promotions more often. Plain text reaches Primary more reliably.

What's the common mistake here?

Hybrid (text-styled HTML that looks plain) is the practical compromise. Single column, no images, hyperlinks instead of buttons.
