Verdicts

Amazon SES

Sending starts at $0.10 per 1,000 emails on the a la carte plan. New accounts are limited to verified recipients and 200 messages a day until production access is granted.

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.

Before you call either

Amazon SES

  1. Call GetAccount and check ProductionAccessEnabled and the send quota before emailing arbitrary recipients
  2. Verify the From domain as an identity first. Sends from unverified identities fail even in production
  3. Use the mailbox simulator (success@simulator.amazonses.com) to test bounces and complaints without hurting reputation
  4. Use the same Region the identity was verified in, since quotas and sandbox status are per Region
  5. On a throttling error, wait and retry the send. SES drops messages over quota rather than queueing them

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
