Email templates

Author, preview, publish, and send reusable templates from the dashboard, an MCP client, or the Unsendbox CLI.

Create a template

Dashboard route: /dashboard/templates.

  1. 01Open Templates and choose New template.
  2. 02Fill in Name, Subject, and an optional Template key, the stable identifier scripts reuse.
  3. 03Write the Email body (HTML) with Liquid placeholders such as {{ firstName }}.
  4. 04Save. The first save publishes revision 1.

Preview and publish a revision

Preview renders the stored body against sample variables before anything is sent.

  1. 01Select a template to open its detail panel and its current published revision.
  2. 02Render a preview to check the merged output for the template variables.
  3. 03Edit the source to start a draft, then save to publish the next revision.
  4. 04Historical revisions stay read-only in the panel.

Revisions are immutable

Saving a template writes a new numbered row in email_template_revision and repoints published_revision_id, instead of rewriting the old revision. A campaign run stores template_revision_id and a sequence stores template_revision_pins, so anything already launched keeps sending the exact body it started with.
