How to use Mandrill API with MailPlugger in Ruby on Rails

Please note that these examples were not tested, but I believe it should work.

Let's use mailer method which was defined here.

Add mandrill-api-json gem to the Gemfile.

gem 'mandrill-api-json'

Then run bundle install command to deploy the gem.

Send

Change the API and MailPlugger.plug_in method in config/initializers/mail_plugger.rb.

class MandrillApiClient
  def initialize(options = {})
    @settings = { api_key: ENV['MANDRILL_API_KEY'] }
    @options = options
  end

  def deliver
    Mandrill::API.new(@settings[:api_key]).messages.send(generate_mail_hash)
  end

  private

  def generate_mail_hash
    {
      from_email: @options[:from].first,
      to: generate_recipients,
      subject: @options[:subject],
      text: @options[:text_part],
      html: @options[:html_part],
      tags: [@options[:tag]]
    }
  end

  def generate_recipients
    @options[:to].map do |to|
      {
        email: to
      }
    end
  end
end

MailPlugger.plug_in('mandrill') do |api|
  api.client = MandrillApiClient
  api.delivery_options = %i[from to subject text_part html_part tag]
  api.delivery_settings = { return_response: true }
end

Then modify the mailer method a little bit.

class TestMailer < ApplicationMailer
  default from: 'from@example.com'

  def send_test
    mail subject: 'Test email', to: 'to@example.com', delivery_system: 'mandrill', tag: 'send_test'
  end
end

Send Raw

Change the API and MailPlugger.plug_in method in config/initializers/mail_plugger.rb.

class MandrillApiClient
  def initialize(options = {})
    @settings = { api_key: ENV['MANDRILL_API_KEY'] }
    @options = options
  end

  def deliver
    Mandrill::API.new(@settings[:api_key]).messages.send_raw(@options[:message_obj].to_s)
  end
end

MailPlugger.plug_in('mandrill') do |api|
  api.client = MandrillApiClient
  api.delivery_options = %i[message_obj]
  api.delivery_settings = { return_response: true }
end

Then modify the mailer method a little bit.

class TestMailer < ApplicationMailer
  default from: 'from@example.com'

  def send_test
    mail subject: 'Test email', to: 'to@example.com', delivery_system: 'mandrill'
