Replace Mailtrap

Captures the mail your app sends in development so you can read it without delivering it to a real inbox.

Why teams move off Mailtrap

A mail sandbox is a subscription for reading email your own application sent. Mounting the outbox removes the reason it exists.

What you give up

Spam scoring and the deliverability checks on captured messages.

This directory says so when an engine only covers part of the job. A replacement that needs a caveat is still worth knowing about — it just should not surprise you in week three.

Yes — Letter Opener Web. It mounts into an application you already run, so there is no second deployment and no second database.
What do I give up by replacing Mailtrap?
Spam scoring and the deliverability checks on captured messages.
How do I replace Mailtrap in a Rails app?
Add letter_opener_web to your Gemfile, mount it in config/routes.rb at /letter_opener, and run its migrations. The whole integration is two lines and a migration.
How much does replacing Mailtrap save?
Mailtrap is priced free tier, paid from $15/mo. The engines here are open source, so the cost becomes the time to mount one and the resources it uses inside your existing application.
