- 02
React Email
TemplatesBest component model for React teams, but governance and ecosystem direction are tied to Resend.
- 03
Maizzle
TemplatesStrong fit for Tailwind teams that want build-time transforms and full HTML control.
- 04
Foundation for Emails
TemplatesOlder but still useful for teams that want Inky, Sass, grid helpers, and Outlook-tested patterns.
- 05
Handlebars
TemplatesGood variable and conditional layer inside existing renderers, but not an email layout framework.
- 06
Liquid
TemplatesBest fit for safe user-editable templates and commerce-style personalization, not responsive layout by itself.

If you are early-stage startups
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
The order above is the general editorial ranking. Re-sorted against best published rate per 1,000, developer experience, and operating track record, the shortlist for a waitlist, a launch announcement, onboarding email, and the first transactional sends becomes Handlebars, Liquid, and MJML. That differs from the headline order, which weighs all audiences together.
