This Ruby gem offers integration with the official API for Mailtrap.

Quickly add email sending functionality to your Ruby application with Mailtrap.

(This client uses API v2, for v1 refer to this documentation)

Add this line to your application's Gemfile:

gem 'mailtrap'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install mailtrap

# place this code in config/environments/production.rb:
config.action_mailer.delivery_method = :mailtrap

# then set the MAILTRAP_API_KEY environment variable
# using your hosting solution.

require 'mailtrap'

# create mail object
mail = Mailtrap::Mail::Base.new(
  from: { email: 'mailtrap@example.com', name: 'Mailtrap Test' },
  to: [
    { email: 'your@email.com' }
  ],
  subject: 'You are awesome!',
  text: "Congrats for sending test email with Mailtrap!"
)

client = Mailtrap::Client.new(api_key: 'your-api-key')
client.send(mail)

mailtrap gem uses Mailtrap API to send emails. Mailtrap API does not try to replicate SMTP. That is why you should expect some limitations when it comes to sending. For example, /api/send endpoint ignores Content-Transfer-Encoding (see headers in the API documentation). Meaning your recipients will receive emails only in the default encoding which is quoted-printable, if you send with Mailtrap API.

For those who does need to use 7bit or any other encoding, SMTP provides better flexibility in that regard. Go to your Mailtrap account → Email Sending → Sending Domains → Your domain → SMTP/API Settings to find the SMTP configuration example.

Change Mailtrap::Sending::Client to Mailtrap::Client.

If you use classes which have Sending namespace, remove the namespace like in the example above.
