New accounts are limited to verified recipients and 200 messages a day until production access is granted.\n\n**Resend API + MCP.** `Idempotency-Key` on POST /emails and /emails/batch, kept for 24 hours. 106 MCP tools load at once, with no toolsets.\n\n## Before you call either\n\n### Amazon SES\n\n1. Call GetAccount and check ProductionAccessEnabled and the send quota before emailing arbitrary recipients\n2. Verify the From domain as an identity first. Sends from unverified identities fail even in production\n3. Use the mailbox simulator (success@simulator.amazonses.com) to test bounces and complaints without hurting reputation\n4. Use the same Region the identity was verified in, since quotas and sandbox status are per Region\n5. On a throttling error, wait and retry the send. SES drops messages over quota rather than queueing them\n\n### Resend API + MCP\n\n1. Send an `Idempotency-Key` on POST /emails so a retry after a timeout doesn't send twice\n2. Send a User-Agent header on raw HTTP calls or you'll get a 403\n3. Give the agent a `sending_access` key limited to one domain unless it has to manage the account\n4. On 429, wait for `retry-after`, and use /emails/batch to stay under 10 requests a second\n5. Verify a domain before sending to anyone but your own address\n\n## Other comparisons with Amazon SES or Resend API + MCP\n\n- [Amazon SES vs Brevo API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-brevo.md)\n- [Amazon SES vs Loops API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-loops.md)\n- [Amazon SES vs Mailgun API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-mailgun.md)\n- [Amazon SES vs Mailjet API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-mailjet.md)\n- [Amazon SES vs Postmark API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-postmark.md)\n- [Amazon SES vs Twilio SendGrid](https://www.anchorterminal.com/compare/amazon-ses-vs-sendgrid.md)\n- [Amazon SES vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-smtp2go.md)\n- [Brevo API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/brevo-vs-resend.md)\n- [Loops API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/loops-vs-resend.md)\n- [Mailgun API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/mailgun-vs-resend.md)\n- [Mailjet API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/mailjet-vs-resend.md)\n- [Postmark API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/postmark-vs-resend.md)\n- [Resend API + MCP vs Twilio SendGrid](https://www.anchorterminal.com/compare/resend-vs-sendgrid.md)\n- [Resend API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/resend-vs-smtp2go.md)\n",
