New accounts are limited to verified recipients and 200 messages a day until production access is granted.\n\n**Twilio SendGrid.** Restricted API keys with per-endpoint scopes, subuser keys and IP access management. No official MCP server that can send, only Twilio's docs search.\n\n## Before you call either\n\n### Amazon SES\n\n1. Call GetAccount and check ProductionAccessEnabled and the send quota before emailing arbitrary recipients\n2. Verify the From domain as an identity first. Sends from unverified identities fail even in production\n3. Use the mailbox simulator (success@simulator.amazonses.com) to test bounces and complaints without hurting reputation\n4. Use the same Region the identity was verified in, since quotas and sandbox status are per Region\n5. On a throttling error, wait and retry the send. SES drops messages over quota rather than queueing them\n\n### Twilio SendGrid\n\n1. Give an agent that only sends a restricted key with just `mail.send`\n2. Set `mail_settings.sandbox_mode` to validate payloads without delivery\n3. Authenticate a domain or verify a single sender before the first send\n4. Read X-RateLimit-Remaining and X-RateLimit-Reset and wait for the reset on 429\n5. Don't blindly retry a timed-out mail/send.
