# Mailtrap

> Email testing sandbox that grew a production sending product.

- Started as the standard way to catch outbound mail in staging
- Fake SMTP inbox showing rendered message, spam score and HTML issues without a real send
- Added a production sending stream with templates, analytics and an EU region
- Testing half is still the best here; sending half is competent but younger than competitors
