About Mailtrap
Mailtrap is an email service for developers and product teams. It covers sending real email through an API or SMTP, and testing email safely before it reaches customers.
What it does
Mailtrap offers an email delivery service for transactional and promotional messages. It also has an email sandbox that catches test messages from staging environments, so developers can check them without sending them to real inboxes. Teams can preview how their emails look across many email clients.
Key features
- Send transactional and promotional email over SMTP or API
- Test staging emails in a sandbox before release
- Preview emails across more than 100 clients and devices
- Sending statistics for opens and bounces
- Support from experts around the clock
Who it's for
Mailtrap suits developers who need to add email to an app, QA staff who check email flows, and product teams that send both transactional and promotional messages. It is easy to connect with common developer tools.
Pricing and good to know
Sign-up is free to start, and the site lists plans for larger sending needs. The sandbox is useful during development because test messages stay out of real inboxes. Deliverability depends on your sending domain and content, so plan time to set up the domain before going live.
