| Free tier | 3,000 emails a month; 1,000 a day with a card on file, 100 without | 100 emails a day, with 1-day log retention |

You send at high volume with heavy routing rules, want email validation as a first-class paid service, or need SMTP relay and large per-call batches alongside the API.
Your stack is TypeScript and you want typed contracts end to end, including an Effect-native SDK. Replies should thread into conversations your product can read, and your coding agents can send through a hosted MCP server.
Log retention is the quiet difference. On Mailgun's Free and Basic plans, send logs disappear after a day, which matters the first time you debug a delivery problem from last week. Retention reaches 30 days on the $90 Scale plan; Samva keeps per-message delivery timelines in the dashboard on every plan.
Mailgun prices validation, retention, and dedicated IPs as separate line items on top of the send ladder, so compare your projected total rather than the base plan price.
