MAIL_UNDELIVERABLE

What it means. The email could not be sent.

What to do. Check the address for a typo, then try again. Nothing about the app itself is affected — this is only the email.

  • HTTP status: 502
  • Retryable after applying the fix: yes

Every failure from the CLI or an MCP tool has this shape:

{
  "ok": false,
  "code": "MAIL_UNDELIVERABLE",
  "message": "The email could not be sent.",
  "fix": "Check the address for a typo, then try again. Nothing about the app itself is affected — this is only the email.",
  "file": "<where to edit, when known>",
  "retryable": true,
  "docs": "https://docs.uarpie.app/errors/MAIL_UNDELIVERABLE"
}

Apply fix (edit file when it is given), then run the same command again.
