Mailtrap

Mailtrap is an all-in-one email delivery platform that helps you capture, inspect, and send emails safely. It provides a dedicated testing environment where you can preview emails and check for spam scores before they ever reach a real inbox. This ensures your staging environment never accidentally emails your actual customers while you are still debugging your code.

You can also use its reliable infrastructure to send production emails via SMTP or REST API. The platform gives you deep insights into deliverability with automated alerts and detailed logs. Whether you are a solo developer or part of a large engineering team, you can manage your entire email lifecycle from a single dashboard with high deliverability rates and easy setup.
