mass_mandrill is thin wrapper around mandrill-api gem that makes sending emails with Mandrill easier and more pleasent to use. Goal is to reasemble Rails' ActiveMailer API.

mass_mandrill supports bulk email sending and Mandrill templates. To learn more about these topics, visit Mandrill Support.

class ExampleMailer < MassMandrill::MandrillMailer

  def example_notice(recipients)
    addresses = recipients.map { |recipient| recipient.email }
    global_merge_vars = [{ name: 'headline', content: 'This is first example notice' }]
    merge_vars = recepients.map do |recipient|
      {
        :rcpt => recipient.email,
        :vars => [{ :name => 'first_name', :content => recipient.first_name }]
      }
    end
    template_content = [{ :name => 'header', :content => '<h1>Hello World</h1>' }]
    
    mail(to: addresses,
         from: 'John Doe <[email protected]>',
         subject: 'This is example notice!',
         template_content: template_content,
         global_merge_vars: global_merge_vars,
         merge_vars: merge_vars)
  end

end

And to send the email:

users = User.all
ExampleMailer.example_notice(users).deliver

Name of the Mandrill template that's going to be used for sending is same as name of the method - in example above example_notice. To override template name, use template parameter:

mail(to: addresses,
     from: 'John Doe <[email protected]>',
     subject: 'This is example notice!',
     template: 'some_other_template',
     global_merge_vars: global_merge_vars,
     merge_vars: merge_vars)

Add mass_mandrill to your Gemfile and bundle. And create Rails initializer with your Mandrill API key:

# config/initializers/mass_mandrill.rb
MassMandrill.config do |config|
  config.api_key = 'YOUR_API_KEY'
end

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
