Manually generate your own pepipost gem

This client library is a Ruby gem which can be compiled and used in your Ruby on Rails project. This library requires a few gems from the RubyGems repository.

  • Open the command line interface/terminal and navigate to the folder of your choice and run the below commands to download and navigate to the downloaded folder: git clone https://github.com/pepipost/pepipost-sdk-ruby.git

  • cd pepipost-sdk-ruby

  • gem build pepipost.gemspec to build the gem.

  • gem install pepipost-5.0.0.gem to install pepipost gem

Building Gem

Once pepipost_gem is installed, use the sample example to send test email.


The following section explains how to use the Pepipost Gem in a new Rails project using RubyMine.

The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

  1. Starting a new project

    Close any existing projects in RubyMine by selecting:

    • File -> Close Project
    • Next, click on Create New Project to create a new project from scratch.

    Create a new project in RubyMine

    • Next, provide TestApp as the project name.
    • Choose Rails Application as the project type.
    • Click OK.

    Create a new Rails Application in RubyMine - step 1

    In the next dialog make sure that correct Ruby SDK is being used (minimum 2.0.0)

    • click OK.

    Create a new Rails Application in RubyMine - step 2

    This will create a new Rails Application project with an existing set of files and folder.

  2. Add reference of the gem

    • In order to use the Pepipost gem in the new project, add a gem reference.
    • Locate the Gemfile in the Project Explorer window under the TestApp project node.
    • The file contains references to all gems being used in the project. Here, add the reference to the library gem by adding the following line: gem 'pepipost_gem', '~> 2.5.0'

    Add references of the Gemfile

  3. Adding a new Rails Controller

    • Once the TestApp project is created.
    • Folder named controllers will be visible in the Project Explorer under the following path: TestApp > app > controllers.
    • Right click on this folder.
    • select New -> Run Rails Generator.

    Run Rails Generator on Controllers Folder

    • Selecting the said option will popup a small window where the generator names are displayed.
    • select the controller template.

    Create a new Controller

    • A popup window will ask you for a Controller name and included Actions.
    • For controller name provide Hello.
    • Include an action named Index.
    • Click OK.

    Add a new Controller

    • A new controller class anmed HelloController will be created in a file named hello_controller.rb containing a method named Index.
    • In this method, copy sample example.
    • Run your project.

    Initialize the library


require 'pepipost'
require 'json'

include Pepipost

api_key = 'Your api_key here'

client = PepipostClient.new(api_key: api_key)

mail_send_controller = client.mail_send

body = Send.new

body.from = From.new

body.from.email = 'hello@your-register-domain-with-pepipost'
body.from.name = 'Example Pepi'
body.subject = 'Emailing with Pepipost is easy'
body.content = []

body.content[0] = Content.new

body.content[0].type = TypeEnum::HTML
body.content[0].value = '<html><body>Hey,<br><br>Do you know integration is even simpler in Pepipost, <br>with Ruby <br> Happy Mailing ! <br><br>Pepipost </body></html>'

body.personalizations = []

body.personalizations[0] = Personalizations.new

body.personalizations[0].to = []

body.personalizations[0].to[0] = EmailStruct.new

body.personalizations[0].to[0].name = 'random-1'
body.personalizations[0].to[0].email = 'random-1@mydomain.name'

  result = mail_send_controller.create_generatethemailsendrequest(body)
  puts (result)
rescue APIException => ex
  puts "Caught APIException: #{ex.message}"
  • Change your api-key and sending domain respectively
    • apikey will be available under Login to Pepipost -> Settings -> Integration
    • Sending Domain will be available under Login to Pepiost -> Settings -> Sending Domains
  *Note :: Domains showing with Active status on Sending Domain dashboard are only allowed to send any sort of emails.* In case there are no Sending Domain added under your account, then first add the domain, get the DNS (SPF/DKIM) settings done and get it reviewed by our compliance team for approval. Once the domain is approved, it will be in ACTIVE status and will be ready to send any sort of emails. 
  • Save above file as sendEmail.rb
  • run ruby sendEmail.rb
