Mandrill for sending emails

We use Mandrill for sending emails in production.

One of the main reasons why we like Mandrill is that the first 12,000 emails per month are always free.

We do not use mail preview services like letter_opener, mailtrap.io, mailcatcher.me, mail_view or mailer preview feature added in Rails 4.2. This is because we actually deliver the email in non-production environments using Mandrill.

Since the first 12,000 emails per month are free, we also use Mandrill to send emails in non-production environments. We use mail_interceptor to intercept and forward emails in a non-production environment.
