Configure
Send email through Resend or an SMTP relay, and test it from Studio.
Kanesh sends invitations and password recovery email through Resend or any SMTP relay. Set it here or in Settings → Email, which also has a test send.

Resend
| Variable | Default | What it does |

A variable that is set wins over Studio and shows as read-only there. To save the SMTP password or Resend key from Studio, set SETTINGS_ENCRYPTION_KEY first; see Security.
