Sends take no idempotency key, the Free plan allows 100 API requests a day, and the terms permit changes without notice.\n\n**SMTP2GO API + MCP.** API keys limited to chosen endpoints, with their own send rate. Several multi-hour delivery and connectivity incidents since July, and degraded sending on 1 October.\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### SMTP2GO API + MCP\n\n1. Give the MCP a key limited to /email/send and the view endpoints it needs, since execute-request can call anything the key allows\n2. Send the key in the `X-Smtp2go-Api-Key` header or as Bearer, not in the JSON body, so it stays out of request logs\n3. Verify a sender domain first. Free accounts without one are held to 25 emails an hour\n4. On 429, pause until calls return 200 again. Repeated errors time out your IP for at least a minute\n5. Check smtp2gostatus.com before blaming your payload for mail stuck as 'processed'\n\n## Questions\n\n### Which is better for AI agents, MailerSend or SMTP2GO API + MCP?\n\nMailerSend scores 69.5 (B) on agent readiness against SMTP2GO API + MCP's 53.1 (D), and leads in 5 of 7 scored categories. SMTP2GO API + MCP leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Do MailerSend and SMTP2GO API + MCP need an API key?\n\nMailerSend takes an API key or an OAuth sign-in. SMTP2GO API + MCP needs an API key.\n\n### Can an agent call MailerSend and SMTP2GO API + MCP without installing anything?\n\nYes. MailerSend has a hosted endpoint at https://api.mailersend.com/v1 and SMTP2GO API + MCP at https://api.smtp2go.com/v3.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/mailersend-vs-smtp2go.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mailersend-vs-smtp2go.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mailersend\", \"b\": \"smtp2go\"}`.
