Templates that
just work

Build reusable templates with Handlebars — or React Email — in a block editor with a live preview, send a test to your own inbox, start from eight gallery designs, and let every save bump the version number.

Questions

Templates, answered

Which template languages does PostFrame support?

Handlebars, with a fixed set of safe helpers (eq, neq, gt, lt, and, or, not, uppercase, lowercase, truncate, formatDate), and React Email, where you write JSX that PostFrame compiles and renders in a sandbox.

How do I use a template when sending?

Pass template_id and a template_variables object on the send call. PostFrame renders the subject and body server-side and queues the finished message.

Can I roll back a template?

PostFrame keeps the version number, not the previous body. Duplicate a template before a large edit if you want a safe copy; the Duplicate action creates it in your workspace.

How do I test a template before it goes live?

Save it, click Send Test in the editor, and enter an address. It goes out through your real provider with a [TEST] subject prefix, so what lands is what customers get.
