- 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.

TemplatesGood variable and conditional layer inside existing renderers, but not an email layout framework.
- 06

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

If you are growth and lifecycle teams
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
The order above is the general editorial ranking. Re-sorted against scheduling, event stream, and operating track record, the shortlist for behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue becomes MJML, React Email, and Maizzle. That matches the headline order, so the general ranking holds for this use case.
