Problem to solve

CLI has great support for deploying many features, even supports using email templates locally. Extending the capability of supabase config push to deploy email templates would continue to support solid deployment workflows. We're aiming to put as much as possible in our repo, so that it can be version controlled, accessed by agents, and reviewed through PRs.

Proposed solution

Add support for deploying auth email templates via supabase CLI

Looks like config push is only pushing the templates subjects. Template HTML bodies are not pushed. Seems to be missed during the native porting #5489

Will raise a fix

Thanks for the fix! The bottom of this docs page lead me to believe you could not use the CLI to deploy auth email templates to Supabase managed projects.

For hosted projects managed by Supabase, copy the templates into the Email Templates section of the Dashboard.
