Confronto email: SendGrid vs Mailgun
This comparison is primarily about operational ownership: whether the team wants a broad sending API or a transactional system with a narrower, more opinionated workflow.
Choose SendGrid when you need a broad API and template ecosystem around several message types. Choose Mailgun when engineering owns sending, validation, and delivery operations.
| SendGrid | Mailgun | |
|---|---|---|
| Prezzo | $20/mo | $35/mo |
| Ideale per | High-volume senders needing proven infrastructure | Developer-heavy teams needing flexibility |
What changes in the operating model?
| Question | SendGrid | Mailgun |
|---|---|---|
| Transactional ownership | Strong API breadth; the team defines more of the operating model | Clear transactional orientation and stream separation |
| Best first test | Send a password reset and an onboarding message through separate categories | Trace a transactional message through delivery and suppression events |
| Main risk | A flexible stack becomes a collection of undocumented conventions | The team expects marketing automation that is outside the core product |

Verdict
Choose SendGrid when you need a broad API and template ecosystem around several message types. Choose Mailgun when engineering owns sending, validation, and delivery operations.
For a fair test, use the same event volume and message classes for two weeks, then compare delivery failures, suppression handling, engineering effort, and downstream product outcomes. A provider’s send rate alone is not evidence that it is the better lifecycle platform.
