MailerSend vs Mailgun

The short answer
Choose MailerSend if…
Teams sending email and SMS from one provider who need a longer activity window than a debugging log — 30 days of activity data against 7 days of API logs is a distinction the rest of this category does not draw.

Choose Mailgun if…

Consider something else if…
- MailerSend: Both paid tiers include the same 50,000 emails, so paying three times more buys features rather than volume, and the entry price is the highest here.
- Mailgun: One day of log retention on the entry plan is the shortest here by a wide margin, and the overage rate is quoted as "from", so the number you plan against is a floor.
