Mandrill DM

Mandrill DM allows you to use ActionMailer with the Mandrill API. Created by Jonathan Berglund and maintained by John Dell, and Kirill Shnurov and various contributors.

On 15.03.2022 Mailchimp blocked tens of thousands of accounts for one reason: their nationality. There's no law that required that. See the email

They didn't give any prior notice, time to migrate, or an option to download our data and email lists. We're unable to log in despite using Mailchimp & Mandrill for 8 years and an excellent account score.

WE'VE LOST ALL OUR DATA and our operations were disrupted.

Mailchimp's actions are completely unlawful, violate business ethics and moral norms. This is pure racism and Nazism. It should not be tolerated.

We urge you to MIGRATE to other services IMMEDIATELY until your account is blocked because of your race, sex, nationality, or T-shirt color.

This gem will continue to work, but will log error on every sent message.

You're free to fork it and keep using Mandrill if you support punishing innocent people for being born in a particular country, no matter what they think about their government and recent events.

First, add the gem to your Gemfile and run the bundle command to install it.

gem 'mandrill_dm'

Second, set the delivery method in config/environments/production.rb.

config.action_mailer.delivery_method = :mandrill

Third, create an initializer such as config/initializers/mandrill.rb and paste in the following code:

MandrillDm.configure do |config|
  config.api_key = ENV['MANDRILL_APIKEY']
  # config.async = false
end

NOTE: If you don't already have an environment variable for your Mandrill API key, don't forget to create one.

If you want to use this gem with mandrill templates you just have to add the template param to the mail function and set the body param to empty string ''.

We use template instead of template_name as described in mandrill documentation since template_name it's used by ActionMailer.

class MyMailer < ActionMailer::Base
  def notify_user(email)
    headers['Reply-To'] = 'your.friend@email.com'
    mail(
      to: email,
      from: 'your@email.com',
      body: '',
      template: 'your-mandrill-template-slug',
      template_content: [ # optional
        {
          name: 'header', # the name of the mc:edit editable region to inject into
          content: 'string to replace a mc:edit="header" in your template', # the content to inject
        },
        {
          name: 'content',
          content: 'string to replace a mc:edit="content" in your template'
        }
      ]
    )
  end
end

This gem was inspired by the letter_opener and mandrill-delivery-handler gems. Special thanks to the folks at MailChimp and Mandrill for their Starter service and Ruby API.
