Enveloop Ruby

Hello! 👋 enveloop-ruby is a Ruby wrapper for the Enveloop API. It simplifies configuring and sending messages (email & SMS/text) via Enveloop inside your Ruby and Ruby on Rails apps.

Enveloop is a developer-focused message builder and API that makes it easy to design & send beautiful emails and texts from your app using a simple implementation. You can sign up for free and be up and running in a couple of minutes!

There are a couple of ways to get started. Using RubyGems, you can install it locally with the following command:

gem install enveloop

Additionally, you can add the following to your application's Gemfile:

gem 'enveloop'

After doing so, you can run the following terminal command:

bundle install

The Enveloop Gem includes helpful methods to interact with the Enveloop API, including:

• send_message
• template_info

We'll talk about how to use some of these methods in the notes to follow.

First, let's set up a connection. You'll need to require the enveloop gem, define a client, and add in your Enveloop API token. Your API token is located in the Settings for each project you have on Enveloop.

require 'enveloop'

enveloop = Enveloop::Client.new(api_key:`ENVELOOP_API_TOKEN')

Now that your connection is established, let's use a method to send a message.

(Note: This method call assumes that you have created a basic template in Enveloop and provides an example of a template variable you may use. Please alter according to how you have set up your template.)

enveloop.send_message(
  template: 'welcome-email',
  to: 'user@email.com',
  from: 'welcome@myapp.com',
  subject: 'Welcome to My App!',
  template_variables: {
    first_name: 'John',
  }
)

If you want to send a message, via Enveloop, and not use an Enveloop template, you can remove the template argument from the method and include the html argument instead (it takes a custom HTML body and creates a structured email message to send out).

enveloop.send_message(
  html: '<h1>Hello John, Welcome to MyApp</h1>',
  to: 'user@email.com',
  from: 'welcome@myapp.com',
  subject: 'Welcome to MyApp',
)

enveloop.send_message(
   template: 'registration-complete',
   to: '+14155551212',
   from: '+12056113369',
   template_variables: {
      first_name: 'Paul'
   }
)

(As you can see, the structure of the send_message method is similar, but we simply swap out an email address for a mobile number. Also, the template used is an SMS template on the Enveloop platform.)

enveloop.template_info(template: 'welcome-email')

Using Enveloop with Ruby on Rails is easy as well. Here is a recommended approach for getting it set up in your Rails application.

Add/update the following lines in your respective Rails environments file.

# remember to never include production keys in files you check into repos.

ENV['ENVELOOP_API_KEY'] = 'ENVELOOP_API_KEY'

config.action_mailer.delivery_method = :enveloop

config.action_mailer.enveloop_settings = { 
  api_key: ENV['ENVELOOP_API_TOKEN']
}

From your command line, use a Rails generator to create a new Enveloop Mailer.

rails generate mailer EnveloopMailer

Now that the mailer is created, you can modify it and add in a custom method, based on your application, to call the send_message method in the Enveloop API.

class EnveloopMailer < ActionMailer::Base

   include Rails.application.routes.url_helpers 

   def new_comment_email(recipient, comment)
      enveloop.send_message(
         template: 'new-comment',
         to: recipient,
         from: 'hello@myapp.com',
         subject: subject,
         template_variables:{
            account_url: 'https://myapp.com',
            user_comment: comment
         }
      )
   end

   private

   def enveloop
      @enveloop ||= Enveloop::Client.new(api_key: ENV['ENVELOOP_API_KEY']) 
   end

end

Now, all that is left is to make a call to send a message, via Enveloop, whenever you need it.

EnveloopMailer.new_comment_email(@comment.user_email_address, @comment.body).deliver_now

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
