There are many alternatives to FakeSMTP for Windows if you are looking for a replacement. 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 10 alternatives to FakeSMTP and eight of them are available for Windows so hopefully you can find a suitable replacement. Other interesting Windows alternatives to FakeSMTP are MailHog, Papercut, MailCatcher and smtp4dev.

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

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.




Windows native app with helpful message rendering.
Very good GUI on windows with a lot of configuration options and viewable headers etc.


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.



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



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.


Should be rated a lot higher. Excellent free alternative to Mailtrap
