POST /v1/messages/send so verification codes, magic links, and password resets go out through your Gork inbox.
Auth mail is single-recipient by nature, so it fits comfortably on the free sandbox — no custom domain required to start.
Pattern
Wire Gork into better-auth’s email callbacks (sendVerificationEmail, and sendVerificationOTP when using the emailOTP plugin). Each callback receives the recipient and content, then POSTs one message:
Tips
- Use a dedicated inbox (e.g.
auth/no-reply) so auth mail is isolated from agent outreach. - Sends are idempotent-safe: pass an
Idempotency-Keyheader keyed on(email, otp)so retries never double-deliver codes. - For production volumes on your own domain, verify the domain first (see the Node.js SDK domains section).
