Sends take no idempotency key, the Free plan allows 100 API requests a day, and the terms permit changes without notice.\n\n**Mailtrap Email API + MCP.** Public OpenAPI 3.1 specs, API tokens with per-resource permissions and expiry dates, and a free plan of 4,000 emails a month without a card support agent use. The MCP server loads 125 tools with no toolsets, no idempotency key was found for sends, and the status page records a sending outage of 1 hour 32 minutes on 1 August 2026.\n\n## Before you call either\n\n### MailerSend\n\n1. Send `Authorization: Bearer \u003ctoken\u003e` to https://api.mailersend.com/v1 and ask for a token with only the scopes the task needs, such as `email_full` and `activity_read`\n2. Read the message id from the `x-message-id` response header. POST /v1/email answers 202 with an empty body\n3. Check for a sent message before retrying a send. No idempotency key exists, so a blind retry can deliver twice\n4. On a 429 wait the seconds in `retry-after`. Call GET /v1/api-quota, which isn't counted, to see the daily quota left\n5. Use POST /v1/bulk-email for batches of up to 500 emails. It isn't on the Free plan and takes 10 to 60 requests a minute by plan\n\n### Mailtrap Email API + MCP\n\n1. Ask the operator to create the first API token at mailtrap.io/settings/api-tokens. The first token can't be created through the API.\n2. Send transactional mail to send.api.mailtrap.io and bulk mail to bulk.api.mailtrap.io. Sandbox sending uses a different base URL and an inbox ID.\n3. Verify a sending domain before the first production send, and use Email Sandbox to test payloads without delivery.\n4. Stay under 150 requests per 10 seconds per token, and 10 per 60 seconds per account on the Stats and Suppressions APIs. On 429, back off until `x-ratelimit-reset`.\n5. Don't retry a timed-out send blindly, because no idempotency key was found. Check the email logs first.\n\n## Questions\n\n### Which is better for AI agents, MailerSend or Mailtrap Email API + MCP?\n\nMailerSend scores 69.5 (B) on agent readiness against Mailtrap Email API + MCP's 66.8 (B), and leads in 3 of 7 scored categories. Mailtrap Email API + MCP leads on schema \u0026 documentation, payments \u0026 pricing, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do MailerSend and Mailtrap Email API + MCP need an API key?\n\nMailerSend takes an API key or an OAuth sign-in. Mailtrap Email API + MCP needs an API key.\n\n### Can an agent call MailerSend and Mailtrap Email API + MCP without installing anything?\n\nYes. MailerSend has a hosted endpoint at https://api.mailersend.com/v1 and Mailtrap Email API + MCP at https://send.api.mailtrap.io.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/mailersend-vs-mailtrap.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mailersend-vs-mailtrap.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mailersend\", \"b\": \"mailtrap\"}`.
