Safe Email Testing With Fake SMTP Server

Testing environment ready in 5 minutes
Each Email Sandbox account comes with an individual testing environment. Integrate it with your app in just a few clicks.
Simple UI for your fake email server

Separate inboxes for each of your environments
Create individual inboxes for different environments or review servers. Or route all emails into one inbox if you prefer.
No real emails are sent
Email Sandbox doesn’t connect to mail servers and captures all emails into a virtual inbox. There’s zero chance of accidentally emailing your users.

Mailtrap can be integrated with any tool that supports SMTP. Use fake SMTP credentials in external tools to test what’s sent on your behalf.
