Postmark Gem

Build Status Code Climate

This gem is the official wrapper for the Postmark HTTP API. Postmark allows you to send your application's emails with high delivery rates, including bounce/spam processing and detailed statistics. In addition, Postmark can parse incoming emails which are forwarded back to your application.

Install the gem

With Bundler:

gem 'postmark'

Without Bundler:

gem install postmark

Get a Postmark API key

In order to send emails using Postmark ruby gem, you will need a Postmark account. If you don't have one please register at https://postmarkapp.com/sign_up.

If you didn’t create any servers yet, please create one, proceed to the Credentials tab and copy an API key. API keys should be frequently rotated for security reasons.

Communicating with the API

Make sure you have a sender signature for every From email address you specify.

Create an instance of Postmark::ApiClient to start sending emails.

your_api_key = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'
client = Postmark::ApiClient.new(your_api_key)

Postmark::ApiClient accepts various options:

client = Postmark::ApiClient.new(your_api_key, secure: true
                                               http_open_timeout: 15)

Some useful options are:

  • secure (true or false): set to true to use SSL connection.
  • http_read_timeout (positive number): limit HTTP read time to n seconds.
  • http_open_timeout (positive number): limit HTTP open time to n seconds.
  • proxy_host (string): proxy address to use.
  • proxy_port (positive number): proxy port to use.
  • proxy_user (string): proxy user.
  • proxy_pass (string): proxy password.

Sending a multipart message

client.deliver(from: '[email protected]',
               to: 'Leonard Hofstadter <[email protected]>',
               subject: 'Re: Anything Can Happen Thursday',
               text_body: 'Apparently the news didn\'t reach my digestive ' \
                          'system, which when startled has it\'s own version ' \

                          'it&rsquo;s own version of &ldquo;Anything Can '\
                          'Happen Thursday&rdquo;</p>')
# => {:to=>"Leonard Hofstadter <[email protected]>", :submitted_at=>"2013-05-09T02:58:00.089828-04:00", :message_id=>"bc973458-1315-xxxx-b295-6aa0a2b631ac", :error_code=>0, :message=>"OK"}

Tagging messages

You can categorize outgoing email using the optional :tag property. If you use different tags for the different types of emails your application generates, you will be able to get detailed statistics for them through the Postmark user interface.

client.deliver(from: '[email protected]',
               to: 'Penny <[email protected]>',
               subject: 'Re: You cleaned my apartment???',
               text_body: 'I couldn\'t sleep knowing that just outside my ' \
                     'bedroom is our living room and just outside our ' \
                     'living room is that hallway and immediately adjacent ' \
                     'to that hallway is this!',
               tag: 'confidential')

# => {:to=>"Penny <[email protected]>", :submitted_at=>"2013-05-09T03:00:55.4454938-04:00", :message_id=>"34aed4b3-3a95-xxxx-bd1d-88064909cc93", :error_code=>0, :message=>"OK"}

Sending to multiple recipients

You can pass multiple recipient addresses in the :to field and the optional :cc and :bcc fields. Note that Postmark has a limit of twenty recipients per message in total. You need to take care not to exceed that limit. Otherwise, you will get an error.

client.deliver(from: '[email protected]',
               to: ['Leonard Hofstadter <[email protected]>',
                    'Penny <[email protected]>'],
               cc: ['Dr. Koothrappali <[email protected]>'],
               bcc: '[email protected]',
               subject: 'Re: Come on, Sheldon. It will be fun.',
               text_body: 'That\'s what you said about the Green Lantern ' \
                          'movie. You were 114 minutes of wrong.')
# => {:to=>"Leonard Hofstadter <[email protected]>, Penny <[email protected]>", :submitted_at=>"2013-05-09T05:04:16.3247488-04:00", :message_id=>"d647c5d6-xxxx-466d-9411-557dcd5c2297", :error_code=>0, :message=>"OK"}

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.

messages = []

messages << {from: '[email protected]',
             to: 'Leonard Hofstadter <[email protected]>',
             subject: 'Re: Come on, Sheldon. It will be fun.',
             text_body: 'That\'s what you said about the Green Lantern ' \
                        'movie. You were 114 minutes of wrong.'}

messages << {from: '[email protected]',
             to: 'Penny <[email protected]>',
             subject: 'Re: You cleaned my apartment???',
             text_body: 'I couldn\'t sleep knowing that just outside my ' \
                        'bedroom is our living room and just outside our ' \
                        'living room is that hallway and immediately ' \
                        'adjacent to that hallway is this!',
             tag: 'confidential'}

client.deliver_in_batches(messages)
# => [{:to=>"Leonard Hofstadter <[email protected]>", :submitted_at=>"2013-05-09T05:19:16.3361118-04:00", :message_id=>"247e43a9-6b0d-4914-a87f-7b74bf76b5cb", :error_code=>0, :message=>"OK"}, {:to=>"Penny <[email protected]>", :submitted_at=>"2013-05-09T05:19:16.3517099-04:00", :message_id=>"26467642-f169-4da8-87a8-b89154067dfb", :error_code=>0, :message=>"OK"}]

Parsing inbound

Inbound processing allows you (or your users) to send emails to Postmark, which we then process and deliver to you via a web hook in a nicely formatted JSON document.

Here is a simple Ruby/Sinatra application that does basic inbound processing.

logger = Logger.new(STDOUT)

class Comment
  attr_accessor :attributes

  def self.create_from_inbound_hook(message)
    self.new(:text => message["TextBody"],
             :user_email => message["From"],
             :discussion_id => message["MailboxHash"])
  end

  def initialize(attributes={})
    @attributes = attributes
  end
end

post '/inbound' do
  request.body.rewind
  comment = Comment.create_from_inbound_hook(Postmark::Json.decode(request.body.read))
  logger.info comment.inspect
end

If you don’t like that the fields of the Inbound JSON document are all in CamelCase, you can use the Postmark::Inbound.to_ruby_hash method to give it some Ruby flavor.

postmark_hash = Postmark::Json.decode(request.body.read)
ruby_hash = Postmark::Inbound.to_ruby_hash(postmark_hash)
# => {:from=>"[email protected]", :from_full=>{:email=>"[email protected]", :name=>"John Doe"}, :to=>"451d9b70cf9364d23ff6f9d51d870251569e+ahoy@inbound.postmarkapp.com", :to_full=>[{:email=>"451d9b70cf9364d23ff6f9d51d870251569e+ahoy@inbound.postmarkapp.com", :name=>""}], :cc=>"\"Full name\" <[email protected]>, \"Another Cc\" <[email protected]>", :cc_full=>[{:email=>"[email protected]", :name=>"Full name"}, {:email=>"[email protected]", :name=>"Another Cc"}], :reply_to=>"[email protected]", :subject=>"This is an inbound message", :message_id=>"22c74902-a0c1-4511-804f2-341342852c90", :date=>"Thu, 5 Apr 2012 16:59:01 +0200", :mailbox_hash=>"ahoy", :text_body=>"[ASCII]", :html_body=>"[HTML(encoded)]", :tag=>"", :headers=>[{:name=>"X-Spam-Checker-Version", :value=>"SpamAssassin 3.3.1 (2010-03-16) onrs-ord-pm-inbound1.wildbit.com"}, {:name=>"X-Spam-Status", :value=>"No"}, {:name=>"X-Spam-Score", :value=>"-0.1"}, {:name=>"X-Spam-Tests", :value=>"DKIM_SIGNED,DKIM_VALID,DKIM_VALID_AU,SPF_PASS"}, {:name=>"Received-SPF", :value=>"Pass (sender SPF authorized) identity=mailfrom; client-ip=209.85.160.180; helo=mail-gy0-f180.google.com; [email protected]; receiver=451d9b70cf9364d23ff6f9d51d870251569e+ahoy@inbound.postmarkapp.com"}, {:name=>"DKIM-Signature", :value=>"v=1; a=rsa-sha256; c=relaxed/relaxed;        d=wildbit.com; s=google;        h=mime-version:reply-to:date:message-id:subject:from:to:cc         :content-type;        bh=cYr/+oQiklaYbBJOQU3CdAnyhCTuvemrU36WT7cPNt0=;        b=QsegXXbTbC4CMirl7A3VjDHyXbEsbCUTPL5vEHa7hNkkUTxXOK+dQA0JwgBHq5C+1u         iuAJMz+SNBoTqEDqte2ckDvG2SeFR+Edip10p80TFGLp5RucaYvkwJTyuwsA7xd78NKT         Q9ou6L1hgy/MbKChnp2kxHOtYNOrrszY3JfQM="}, {:name=>"MIME-Version", :value=>"1.0"}, {:name=>"Message-ID", :value=>"<CAGXpo2WKfxHWZ5UFYCR3H_J9SNMG+5AXUovfEFL6DjWBJSyZaA@mail.gmail.com>"}], :attachments=>[{:name=>"myimage.png", :content=>"[BASE64-ENCODED CONTENT]", :content_type=>"image/png", :content_length=>4096}, {:name=>"mypaper.doc", :content=>"[BASE64-ENCODED CONTENT]", :content_type=>"application/msword", :content_length=>16384}]}

Working with messages

Use #get_messages to retrieve messages (:count and :offset parameters control pagination). Access inbound messages by passing :inbound => true as a parameter.

client.get_messages(count: 1, offset: 0)
# => [{:message_id=>"41f03342-xxxx-xxxx-xxxx-558caedb5e82", :to=>[{"Email"=>"[email protected]", "Name"=>nil}], :cc=>[], :bcc=>[], :recipients=>["[email protected]"], :received_at=>"2014-01-15T16:41:22.4533537-05:00", :from=>"\"Postmark\" <[email protected]>", :subject=>"Good Luck With The Gem", :attachments=>[]}]

Use #get_message to get details for a specific message using ID:

client.get_message('41f03342-xxxx-xxxx-xxxx-558caedb5e82')
# => {:text_body=>"...", :body=>"...", :message_id=>"41f03342-xxxx-xxxx-xxxx-558caedb5e82", :to=>[{"Email"=>"[email protected]", "Name"=>nil}], :cc=>[], :bcc=>[], :recipients=>["[email protected]"], :received_at=>"2014-01-15T16:41:22.4533537-05:00", :from=>"\"Postmark\" <[email protected]>", :subject=>"Good Luck With The Gem", :attachments=>[]}

Use #dump_message to get the full message body:

client.dump_message('41f03342-xxxx-xxxx-xxxx-558caedb5e82')
# => {:body=>"..."}

You can get more details about the underlying endpoints and parameters they accept in Postmark Developer Docs.

Working with bounces

Use #get_bounces to retrieve a list of bounces (use :count and :offset parameters to control pagination).

client.get_bounces(count: 1, offset: 0)
# => [{:id=>654714902, :type=>"Transient", :type_code=>2, :name=>"Message delayed", :message_id=>"1fdf3729-xxxx-4d5c-8a7b-96da7a23268b", :description=>"The server could not temporarily deliver your message (ex: Message is delayed due to network troubles).", :details=>"action: failed\r\n", :email=>"[email protected]", :bounced_at=>"2013-04-10T01:01:35.0965184-04:00", :dump_available=>true, :inactive=>false, :can_activate=>true, :subject=>"bounce test"}]

Use #get_bounced_tags to retrieve a list of tags used for bounced emails.

client.get_bounced_tags
# => ["confidential"]

Use #get_bounce to get info for a specific bounce using ID:

client.get_bounce(654714902)
# => {:id=>654714902, :type=>"Transient", :type_code=>2, :name=>"Message delayed", :message_id=>"1fdf3729-xxxx-xxxx-8a7b-96da7a23268b", :description=>"The server could not temporarily deliver your message (ex: Message is delayed due to network troubles).", :details=>"action: failed\r\n", :email=>"[email protected]", :bounced_at=>"2013-04-10T01:01:35.0965184-04:00", :dump_available=>true, :inactive=>false, :can_activate=>true, :subject=>"bounce test", :content=>"..."}

Use #dump_bounce to get the full bounce body:

client.dump_bounce(654714902)
# => {:body=>"Return-Path: <>\r\nReceived: from m1.mtasv.net (74.205.19.136) by sc-ord-mail2.mtasv.net id hcjov61jk5ko for <[email protected]>; Wed, 10 Apr 2013 01:00:35 -0400 (envelope-from <>)\r\nDate: Wed, 10 Apr 2013 01:00:48 -0400\r\nFrom: [email protected]\r\n..."}

You can activate email addresses that were disabled due to a hard bounce by using #activate_bounce:

client.activate_bounce(654714902)
# => {:id=>654714902, :type=>"Transient", :type_code=>2, :name=>"Message delayed", :message_id=>"1fdf3729-xxxx-xxxx-xxxx-96da7a23268b", :description=>"The server could not temporarily deliver your message (ex: Message is delayed due to network troubles).", :details=>"action: failed\r\n", :email=>"[email protected]", :bounced_at=>"2013-04-10T01:01:35.0965184-04:00", :dump_available=>true, :inactive=>false, :can_activate=>true, :subject=>"bounce test"}

Getting delivery stats

Currently delivery stats only include a summary of inactive emails and bounces by type.

stats = client.delivery_stats
# => {:inactive_mails=>1, :bounces=>[{:name=>"All", :count=>3}, {:type=>"HardBounce", :name=>"Hard bounce", :count=>2}, {:type=>"Transient", :name=>"Message delayed", :count=>1}]}

Server Info

The gem also allows you to read and update the server info:

client.server_info
# => {:name=>"Testing", :color=>"blue", :bounce_hook_url=>"", :inbound_hash=>"c2ffffff74f8643e5f6086c81", :inbound_hook_url=>"", :smtp_api_activated=>true}

For example, you can use #update_server_info to set inbound hook URL:

client.update_server_info inbound_hook_url: 'http://example.org/bounces'

Using Postmark with the Mail library

You can use Postmark with the mail gem.

gem install mail

Make sure you have a sender signature for every From email address you specify.

To send a Mail::Message via Postmark you’ll need to specify Mail::Postmark as a delivery method for the message:

message = Mail.new do
  # ...
  delivery_method Mail::Postmark, api_key: 'your-postmark-api-key', secure: true
end

Delivery method accepts all options supported by Postmark::ApiClient documented above. A new instance of Postmark::ApiClient is created every time you deliver a message to preserve thread safety.

Plain text message

require 'rubygems'
require 'postmark'
require 'mail'
require 'json'

message = Mail.new do
  from            '[email protected]'
  to              'Leonard Hofstadter <[email protected]>'
  subject         'Re: Come on, Sheldon. It will be fun.'
  body            'That\'s what you said about the Green Lantern movie. You' \
                  'were 114 minutes of wrong.'

  delivery_method Mail::Postmark, :api_key => 'your-postmark-api-key'
end

message.deliver
# => #<Mail::Message:70355890541720, Multipart: false, Headers: <From: [email protected]>, <To: [email protected]>, <Message-ID: e439fec0-4c89-475b-b3fc-eb446249a051>, <Subject: Re: Come on, Sheldon. It will be fun.>>

Message with attachments

message = Mail.new do
  from            '[email protected]'
  to              'Dr. Sheldon Cooper <[email protected]>'
  subject         'Have you seen these pictures of yours?'
  body            'You look like a real geek!'
  add_file        '1.jpeg'

  delivery_method Mail::Postmark, :api_key => 'your-postmark-api-key'
end

message.attachments['sheldon.jpeg'] = File.read('2.jpeg')

message.deliver
# => #<Mail::Message:70185826686240, Multipart: true, Headers: <From: [email protected]>, <To: [email protected]>, <Message-ID: ba644cc1-b5b1-4bcb-aaf8-2f290b5aad80>, <Subject: Have you seen these pictures of yours?>, <Content-Type: multipart/mixed; boundary=--==_mimepart_5121f9f1ec653_12c53fd569035ad817726>>

You can also make an attachment inline:

message.attachments.inline['sheldon.jpeg'] = File.read('2.jpeg')

Then simply use Mail::Part#url method to reference it from your email body.

<p><img src="<%= message.attachments['sheldon.jpeg'].url %>" alt="Dr. Sheldon Cooper"></p>

Multipart message

You can send multipart messages containing both text and HTML using the Postmark gem.

require 'rubygems'
require 'postmark'
require 'mail'
require 'json'

message = Mail.new do
  from            '[email protected]'
  to              'Leonard Hofstadter <[email protected]>'
  subject         'Re: Anything Can Happen Thursday'
  delivery_method Mail::Postmark, :api_key => 'your-postmark-api-key'

  text_part do
    body          'Apparently the news didn\'t reach my digestive system,' \
                  ' which when startled has it\'s own version of "Anything' \
                  ' Can Happen Thursday"'
  end

  html_part do
    content_type  'text/html; charset=UTF-8'
    body          '<p>Apparently the news didn&rsquo;t reach my digestive ' \
                  'system, which when startled has it&rsquo;s own version ' \

Postmark also lets you tag your messages.

require 'rubygems'
require 'postmark'
require 'mail'
require 'json'

message = Mail.new do
  from           '[email protected]'
  to             'Penny <[email protected]>'
  subject        'Re: You cleaned my apartment???'
  body           'I couldn\'t sleep knowing that just outside my bedroom is ' \
                 'our living room and just outside our living room is that ' \
                 'hallway and immediately adjacent to that hallway is this!'
  tag            'confidential'

  delivery_method Mail::Postmark, :api_key => 'your-postmark-api-key'
end

message.deliver
# => #<Mail::Message:70168327829580, Multipart: false, Headers: <From: [email protected]>, <To: [email protected]>, <Message-ID: af2570fd-3481-4b45-8b27-a249806d891a>, <Subject: Re: You cleaned my apartment???>, <TAG: confidential>>

Sending in batches

You can also send Mail::Message objects in batches. Create an instance of Postmark::ApiClient as described in "Communicating with the API" section.

messages = []

messages << Mail.new do
  from            '[email protected]'
  to              'Leonard Hofstadter <[email protected]>'
  subject         'Re: Come on, Sheldon. It will be fun.'
  body            'That\'s what you said about the Green Lantern movie. You' \
                  'were 114 minutes of wrong.'
end

messages << Mail.new do
  from           '[email protected]'
  to             'Penny <[email protected]>'
  subject        'Re: You cleaned my apartment???'
  body           'I couldn\'t sleep knowing that just outside my bedroom is ' \
                 'our living room and just outside our living room is that ' \
                 'hallway and immediately adjacent to that hallway is this!'
  tag            'confidential'
end

client.deliver_messages(messages)
# => [{:to=>"[email protected]", :submitted_at=>"2013-05-10T01:59:29.830486-04:00", :message_id=>"8ad0e8b0-xxxx-xxxx-951d-223c581bb467", :error_code=>0, :message=>"OK"}, {:to=>"[email protected]", :submitted_at=>"2013-05-10T01:59:29.830486-04:00", :message_id=>"33c6240c-xxxx-xxxx-b0df-40bdfcf4e0f7", :error_code=>0, :message=>"OK"}]

After delivering a batch you can check on each message’s delivery status:

messages.first.delivered?
# => true

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

Or even get a related Postmark response:

messages.first.postmark_response
# => {"To"=>"[email protected]", "SubmittedAt"=>"2013-05-10T01:59:29.830486-04:00", "MessageID"=>"8ad0e8b0-xxxx-xxxx-951d-223c581bb467", "ErrorCode"=>0, "Message"=>"OK"}

Accessing Postmark Message-ID

You might want to save identifiers of messages you send. Postmark provides you with a unique Message-ID, which you can use to retrieve bounces later. This example shows you how to access the Message-ID of a sent email message.

message = Mail.new
# ...
message.deliver

message['Message-ID']
# => cadba131-f6d6-4cfc-9892-16ee738ba54c
message.message_id
# => "cadba131-f6d6-4cfc-9892-16ee738ba54c"

Exploring Other Gem Features

To provide an interface similar to ActiveRecord for bounces, the Postmark gem adds Postmark::Bounce class. This class uses the shared Postmark::ApiClient instance configured through the Postmark module.

require 'rubygems'
require 'postmark'
require 'mail'
require 'json'

Postmark.response_parser_class = :Json
Postmark.api_key = 'your-postmark-api-key'

# Get bounces information: (array of bounce objects)
Postmark::Bounce.all
# => [#<Postmark::Bounce:0x007ff09c04ae18 @id=580516117, @email="[email protected]", @bounced_at=2012-10-21 00:01:56 +0800, @type="HardBounce", @name=nil, @details="smtp;550 5.1.1 The email account that you tried to reach does not exist.

# Find specific bounce by id:
bounce = Postmark::Bounce.find(5)
# => #<Postmark::Bounce:0x007ff09c04ae18 @id=580516117, @email="[email protected]", @bounced_at=2012-10-21 00:01:56 +0800, @type="HardBounce", @name=nil, @details="smtp;550 5.1.1 The email account that you tried to reach does not exist.

bounce.dump     # string, containing raw SMTP data

Requirements

You will need a Postmark account, server and sender signature set up to use it. If you plan using it in a Rails project, check out the postmark-rails gem, which is meant to integrate with ActionMailer.

The plugin will try to use ActiveSupport Json if it is already included. If not, it will attempt using the built-in Ruby Json library.

You can also explicitly specify which one to be used, using

Postmark.response_parser_class = :Json # :ActiveSupport or :Yajl are also supported.

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history.
  • Send me a pull request. Bonus points for topic branches.
