## Verdicts

**Brevo API + MCP.** POST /v3/smtp/email allows 1,000 requests a second on every plan. Eight 'multiple services' full outages on the status page since July.

**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.

## Before you call either

### Brevo API + MCP

1. Connect a single module server at /v1/brevo_<module>/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

### Mailtrap Email API + MCP

1. 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.
2. 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.
3. Verify a sending domain before the first production send, and use Email Sandbox to test payloads without delivery.
4. 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`.
5. Don't retry a timed-out send blindly, because no idempotency key was found. Check the email logs first.
