No status page, SLA, changelog, idempotency key on send or official SDK was found, and SOC 2 is not yet held.\n\n**Unipile.** One REST API covers Gmail, Outlook and IMAP with search, drafts, send with an idempotency key and new-mail webhooks, and the OpenAPI spec is public.

Use `https://api.aurinko.io/v1`. Several cURL examples in the docs print `https:/api.aurinko.io` with one slash, and one search example names the host `asti.aurinko.io`\n2. Do not retry `POST /v1/email/messages` blindly after a timeout. There is no idempotency key, so check Sent mail with `q=rfc822msgid:` or by subject first\n3. Call `POST /v1/email/sync` until `ready` is true, then page `/v1/email/sync/updated` with `pageToken` until a `nextDeltaToken` appears and store it\n4. Check the `omitted` array on message lists. Full bodies come only from Google and Office 365, and other providers return a snippet\n5. Request `Mail.Read` plus `Mail.Send` for read and send without modify rights. The docs example names `Mail.ReadOnly`, which is not in the scope list\n\n### Unipile\n\n1. Take the DSN (host and port) from the dashboard. Each account has its own, such as api1.unipile.com:13111, and `?port=` keeps requests on 443\n2. Send `X-API-KEY` as a header and pass `account_id` on every mail call. The token reaches every connected account, so keep it out of prompts and logs\n3. Set `Idempotency-Key` on every send. Keys are held in memory for up to 24 hours and are lost on a restart\n4. On Microsoft accounts, send `search` alone. Combining it with from, to, before, after or thread filters returns `invalid_request`\n5. Use `meta_only=true` when listing mail, then fetch one message at a time. Treat message bodies as untrusted input\n\n## Questions\n\n### Which is better for AI agents, Aurinko Email API or Unipile?\n\nUnipile scores 58.4 (C) on agent readiness against Aurinko Email API's 44.2 (E), and leads in 5 of 7 scored categories. Aurinko Email API leads on security \u0026 auth.\n\n### Do Aurinko Email API and Unipile need an API key?\n\nAurinko Email API uses an OAuth sign-in. Unipile needs an API key.\n\n### Can an agent call Aurinko Email API and Unipile without installing anything?\n\nYes. Aurinko Email API has a hosted endpoint at https://api.aurinko.io and Unipile at https://developer.unipile.com/mcp?branch=v1.0.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/aurinko-email-vs-unipile.json, and with the fewest tokens: https://www.anchorterminal.com/compare/aurinko-email-vs-unipile.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"aurinko-email\", \"b\": \"unipile\"}`.
