Eight 'multiple services' full outages on the status page since July. **Resend API + MCP.** `Idempotency-Key` on POST /emails and /emails/batch, kept for 24 hours. 106 MCP tools load at once, with no toolsets. ## Before you call either ### Brevo API + MCP 1. Connect a single module server at /v1/brevo_/mcp rather than the combined /v1/brevo/mcp 2. Send with POST /v3/smtp/email and the `api-key` header, not Bearer 3. Use webhooks for delivery events. GET /v3/smtp/emails allows 2 requests a second 4. Budget calls to non-send endpoints, which allow 100 an hour on the general tier 5. Wait for account approval before counting on the free plan's 300 a day ### Resend API + MCP 1. Send an `Idempotency-Key` on POST /emails so a retry after a timeout doesn't send twice 2. Send a User-Agent header on raw HTTP calls or you'll get a 403 3. Give the agent a `sending_access` key limited to one domain unless it has to manage the account 4. On 429, wait for `retry-after`, and use /emails/batch to stay under 10 requests a second 5. Verify a domain before sending to anyone but your own address ## Other comparisons with Brevo API + MCP or Resend API + MCP - [Amazon SES vs Brevo API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-brevo.md) - [Amazon SES vs Resend API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-resend.md) - [Brevo API + MCP vs Loops API + MCP](https://www.anchorterminal.com/compare/brevo-vs-loops.md) - [Brevo API + MCP vs Mailgun API + MCP](https://www.anchorterminal.com/compare/brevo-vs-mailgun.md) - [Brevo API + MCP vs Mailjet API + MCP](https://www.anchorterminal.com/compare/brevo-vs-mailjet.md) - [Brevo API + MCP vs Postmark API + MCP](https://www.anchorterminal.com/compare/brevo-vs-postmark.md) - [Brevo API + MCP vs Twilio SendGrid](https://www.anchorterminal.com/compare/brevo-vs-sendgrid.md) - [Brevo API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/brevo-vs-smtp2go.md) - [Loops API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/loops-vs-resend.md) - [Mailgun API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/mailgun-vs-resend.md) - [Mailjet API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/mailjet-vs-resend.md) - [Postmark API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/postmark-vs-resend.md) - [Resend API + MCP vs Twilio SendGrid](https://www.anchorterminal.com/compare/resend-vs-sendgrid.md) - [Resend API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/resend-vs-smtp2go.md)
