postmark-rails gem

Build Status Code Climate

The Postmark Rails Gem is a drop-in plug-in for ActionMailer to send emails via Postmark, an email delivery service for web apps. The gem has been created for fast implementation and fully supports all of Postmark’s features.

Supported Rails Versions

  • Rails 4.0
  • Rails 3.x

For Rails 2.3 please take a look at version 0.4. It may miss some new features, but receives all required bug fixes and other support if needed.

Configuring your Rails application

Add this to your Gemfile: (change version numbers if needed)

gem 'postmark-rails', '~> 0.5.2'

Don’t forget to run bundle install command every time you change something in the Gemfile.

Add this to your config/application.rb:

config.action_mailer.delivery_method = :postmark
config.action_mailer.postmark_settings = { :api_key => "your-api-key" }

The postmark_settings hash can contain all options supported by Postmark::ApiClient.

For the API details, refer to the developer documentation.

Tagging your deliveries

You can use tags to categorize outgoing messages and attach application-specific information. Tagging the different types of email that you send lets you review statistics and bounce reports separately.

class TestMailer < ActionMailer::Base

  def tagged_message
    mail(
      :subject => 'hello',
      :to      => 'sheldon@bigbangtheory.com',
      :from    => 'leonard@bigbangtheory.com',
      :tag     => 'my-tag'
    )
  end

end

Sending attachments

You can also send file attachments with Postmark. Read our Developer docs for additional information.

The Postmark gem is compatible with ActionMailer attachments API. It allows you to specify the name, content-type and other attributes for your attachments.

The legacy :postmark_attachments attribute is no longer supported on Rails 3.2.13 and above.

class TestMailer < ActionMailer::Base

  def message_with_attachment
    attachments.inline['logo.png'] = File.read("/path/to/image") # Inline image
    attachments['42.jpg'] = File.read("/path/to/file") # Attached file
    mail(
      :subject              => 'hello',
      :to                   => 'sheldon@bigbangtheory.com',
      :from                 => 'leonard@bigbangtheory.com'
    )
  end

end

Sending in batches

While Postmark is focused on transactional email, we understand that developers with higher volumes or processing time constraints need to send their messages in batches. To facilitate this we provide a batching endpoint that permits you to send up to 500 well-formed Postmark messages in a single API call.

client = Postmark::ApiClient.new('your-api-key')

messages = []
messages << DigestMailer.weekly_digest(@user1)
messages << DigestMailer.weekly_digest(@user2)

client.deliver_messages(messages)

messages.first.delivered?
# => true

messages.all?(&:delivered)
# => true
