- 01
MJML
TemplatesMature, vendor-neutral, and purpose-built to compile responsive markup into the table-based HTML older clients still require.
- 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 developers picking email infrastructure
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.
The order above is the general editorial ranking. Re-sorted against developer experience, SDK breadth, and idempotency keys, the shortlist for password resets, receipts, and magic links shipped from application code becomes Handlebars, Liquid, and MJML. That differs from the headline order, which weighs all audiences together.
