Enveloop provides the Enveloop Ruby wrapper for our Enveloop API. It simplifies configuring and sending messages (email & SMS/text) via Enveloop inside your Ruby apps.

Installing the Enveloop Ruby Gem

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

Using the Enveloop Gem

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.

Setting up a Connection

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.)

Send an email message using an Enveloop Template

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

Send an email message using custom HTML

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).

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

Send a text/SMS message using an Enveloop Template

Along with email messages, you can also send text/SMS messages via Enveloop. In this example, the registration-complete template is an SMS template. Therefore, Enveloop can accept mobile numbers for to/from.

   template: 'registration-complete',
   to: '+14155551212',
   from: '+12056113369',
   template_variables: {
      first_name: 'Paul'

Get information about an Enveloop template (variables, body HTML)
