Postmark gem

Ruby gem for sending emails through postmarkapp.com HTTP API

Install

The gem is hosted at gemcutter. If you don’t have it, install it first:

sudo gem install gemcutter

Then

sudo gem install postmark

Example

#!/usr/bin/env ruby

require 'rubygems'
require 'postmark'
require 'tmail'

Postmark.api_key = "your-api-key"

message = TMail::Mail.new
# make sure you have a sender signature with that email
# from and to also accept arrays of emails.
message.from = "[email protected]"
message.to = "Sheldon Cooper <[email protected]>"
message.subject = "Hi Sheldon!"
message.content_type = "text/html"
message.body = "Hello my friend!"
# set custom headers at will.
message["CUSTOM-HEADER"] = "my custom header value"
# tag message
message.tag = "my-tracking-tag"
# set reply to if you need; also, you can pass array of emails.
message.reply_to = "[email protected]"

p Postmark.send_through_postmark(message).body

You can retrieve various information about your server state using the Public bounces API - developer.postmarkapp.com/bounces

# get delivery stats
Postmark.delivery_stats # json
Postmark::Bounce.all # [ bounce, bounce ... ]
bounce = Postmark::Bounce.find(bounce_id) # Bounce
bounce.dump # string, containing raw SMTP data
bounce.reactivate # reactivate hard bounce

Encryption

To use SSL encryption when sending email configure the library as follows:

Postmark.secure = true

Requirements

The gem relies on TMail for building the message. You will also need 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 is also supported.

Limitations

Currently postmark API does not support attachments. For more information, check the docs at:

developer.postmarkapp.com
