Paubox Rails

This gem extends the Paubox Ruby Gem for use with ActionMailer in Ruby on Rails.

The Paubox Email API allows your application to send secure, HIPAA compliant email via Paubox and track deliveries and opens.

Compatibility

This gem has been tested and confirmed working with Rails 4-6

Installation

Add this line to your application's Gemfile:

gem 'paubox_rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paubox_rails

Getting Paubox API Credentials

You will need to have a Paubox account. You can sign up here.

Once you have an account, follow the instructions on the Rest API dashboard to verify domain ownership and generate API credentials.

Configuring API Credentials

Create a new file at config/initializers/paubox.rb and add the following.

Paubox.configure do |config|
  config.api_key = ENV['PAUBOX_API_KEY']
  config.api_user = ENV['PAUBOX_API_USER']
end

Note: Keep your unencrypted API credentials out of version control. Set as environment variables in a file that's not checked into version control, such as config/application.yml or config/secrets.yml. Better yet, use Rails Encrypted Secrets.

Setting ActionMailer Delivery Method

Add the following to the configuration block in config/application.rb or the desired environment config in config/environments (e.g. config/environments/production.rb for production.)

config.action_mailer.delivery_method = :paubox

Usage

You can use Action Mailer as you normally would in a Rails app.

See the Paubox Ruby Gem for more advanced usage examples.

Allowing non-TLS message delivery with Action Mailer

Set allow_non_tls to true in the delivery_method_options hash argument and pass this into the mailer action.

For example:

class UserMailer < ApplicationMailer
  def welcome_email
    @user = params[:user]
    @url  = user_url(@user)
    delivery_options = { allow_non_tls: true }
    mail(to: @user.email,
         subject: "Welcome!",
         delivery_method_options: delivery_options)
  end
end
