Create templates
Invalid MJML in a preview request now returns
422 invalid_template_mjml (previously returned 500). Update error handling to check for 422 with code invalid_template_mjml when previewing templates.Create a drip campaign
Suppressions and unsubscribe
Suppression endpoints help prevent sends to blocked or unsubscribed addresses:Email routes currently remain under
/v1/... instead of /api/v1/.... Treat the generated API reference as the exact path source for email until those routes are folded into the canonical API prefix.Drip admin enrollment
Admin enrollment endpoints (POST /enroll, DELETE /exit, and list enrollments) are wired but the underlying campaign-authoring surface (create/update/delete campaigns and steps) is not yet built. Calling those unbuilt methods returns 404 with code drip_admin_surface_unavailable instead of a 500. Track the campaign-authoring surface under the email phase-B milestone.
