Choose Mailgun when

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.

Choose Samva when

You want typed TypeScript contracts, inbound that threads into conversations, delivery history on every plan, and overage at $0.50 per 1,000 with a spend cap. Mailgun meters overage from $1.80 per 1,000 on Basic down to $1.10 on Scale, and Free and Basic drop logs after a day.

Log retention is the quiet tax. On Mailgun Free and Basic, send logs disappear after a day. That 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. Price the line items you will use, then compare totals.
