Mailtrap is not available for Windows but there are some alternatives that runs on Windows with similar functionality. The best Windows alternative is Mailpit, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to Mailtrap and nine of them are available for Windows so hopefully you can find a suitable replacement. Other interesting Windows alternatives to Mailtrap are MailHog, FakeSMTP, Papercut and MailCatcher.

MailHog is an email testing tool inspired by MailCatcher, but easier to install.



FakeSMTP is a Free Fake SMTP Server with GUI for testing emails in applications easily. It is written in Java.



Papercut is a simplified SMTP server designed to only receive messages (not to send them on) with a GUI on top of it allowing you to see the messages it receives.




MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface. Run mailcatcher, set your favourite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check out http://127.0.0.



Origami SMTP was created with the idea to have a fake email server for testing purposes that supported TLS. This is because the code the developer was working on at the time had several hard coded values enforcing TLS so most other solutions would not work.


LunaticSMTP is a dummy SMTP server with desktop GUI for testing email sending applications.



MailPit is the continuation of this product.
