Mailtrap intro


Safe Email Testing


Mailtrap is a fake SMTP server for development teams to test, view and share emails sent from the development and staging environments without spamming real customers.

Mailtrap keeps test messages away from your personal or work inboxes thus avoiding the embarassing situation when you accidentaly send a test email to a client while testing your app. In addition to that, Mailtrap allows sharing inboxes with the team, auto-forwarding emails, spam analysis for emails, etc.

Really impressed with @Mailtrap (from our friends at @Railsware). If you need to debug web apps that send email, check em out.

Great service! Thank you! Analysis for spam is really awesome!

Josh Moody

Experimenting with @mailtrap for sending test emails from apps. Wow! I wish I'd discovered this a long time ago!

Have you ever sent emails from staging to real customers? Yeah, we did that too... Before Mailtrap.

Mailtrap is a good example of the tool that has been initially created by Railsware team for internal use and then shared freely with other developers later on. The product idea has come naturally out of the needs our team had and been developed by Railswarians from scoping and design to the technical implementation and support.

Mailtrap development is still on as we're introducing paid versions of the product with more features included.
