- 03
Maizzle
TemplatesStrong fit for Tailwind teams that want build-time transforms and full HTML control.

Foundation for Emails
TemplatesOlder but still useful for teams that want Inky, Sass, grid helpers, and Outlook-tested patterns.

Liquid
TemplatesBest fit for safe user-editable templates and commerce-style personalization, not responsive layout by itself.

If you are SaaS product teams
A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.
The order above is the general editorial ranking. Re-sorted against multi-tenant support, event stream, and the suppressions API, the shortlist for trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail becomes MJML, React Email, and Maizzle. That matches the headline order, so the general ranking holds for this use case.
