Preview email in the browser instead of sending it. This means you do not need to set up email delivery in your development environment, and you no longer need to worry about accidentally sending a test email to someone else's address.
First add the gem to your development environment and run the bundle command to install it.
gem "letter_opener", :group => :development
Then set the delivery method in config/environments/development.rb
config.action_mailer.delivery_method = :letter_opener
Now any email will pop up in your browser instead of being sent. The messages are stored in tmp/letter_opener.
If you aren't using Rails, this can be easily set up with the Mail gem. Just set the delivery method when configuring Mail and specify a location.
require "letter_opener" Mail.defaults do delivery_method LetterOpener::DeliveryMethod, :location => "tmp/letter_opener" end
