Ruby on Rails Mailjet step by step setup and configuration

Integrating Mailjet into a Ruby on Rails project is a straightforward process that involves configuring the Mailjet API credentials, creating email templates, and using the Mailjet API to send transactional emails. Here are the steps to integrate Mailjet into a Ruby on Rails project:

Step 1: Install the Mailjet Ruby Gem The first step is to install the Mailjet Ruby gem, which provides a simple interface for interacting with the Mailjet API. You can install the gem by adding the following line to your Gemfile:

gem 'mailjet'

Then, run the following command to install the gem:

bundle install

Step 2: Configure the Mailjet API Credentials Next, you need to configure the Mailjet API credentials in your Rails application. You can do this by adding the following lines to your config/application.rb file:

config.action_mailer.delivery_method = :mailjet
config.action_mailer.mailjet_settings = {
  api_key: ENV['MAILJET_API_KEY'],
  secret_key: ENV['MAILJET_SECRET_KEY']
}

Make sure to replace ENV['MAILJET_API_KEY'] and ENV['MAILJET_SECRET_KEY'] with your actual Mailjet API key and secret key.

Step 3: Create Email Templates Now, you can create email templates using HTML and CSS. You can create a new file in the app/views directory, such as app/views/user_mailer/welcome.html.erb, and add your HTML and CSS code for the email template.

Step 4: Use the Mailjet API to Send Emails Finally, you can use the Mailjet API to send transactional emails. You can do this by creating a new mailer class, such as UserMailer, and defining a method for sending the email. Here's an example code block:

class UserMailer < ApplicationMailer
  def welcome_email(user)
    @user = user
    mail(to: @user.email, subject: 'Welcome to My App')
  end
end

In this example, we define a welcome_email method that takes a user object as a parameter. We then set the @user instance variable to the user parameter, and use the mail method to send the email to the user's email address with a subject of "Welcome to My App". To use this method, you can call it from your controller or other parts of your application, like this:

UserMailer.welcome_email(@user).deliver_now

This will send the welcome email to the user's email address using the Mailjet API.

Mailjet configuration options in Ruby on Rails

Here are the Mailjet configuration options for Ruby on Rails integration along with their short explanations:

1. api_key: Your Mailjet API key. This is required to authenticate your requests to the Mailjet API.
2. secret_key: Your Mailjet secret key. This is also required to authenticate your requests to the Mailjet API.
3. default_from: The default email address to use as the sender for all emails sent through Mailjet.
4. default_from_name: The default name to use as the sender for all emails sent through Mailjet.
5. default_reply_to: The default email address to use as the reply-to address for all emails sent through Mailjet.
6. default_subject: The default subject line to use for all emails sent through Mailjet.
7. default_template_id: The default email template ID to use for all emails sent through Mailjet.
8. default_variables: A hash of default variables to use in all emails sent through Mailjet.
9. sandbox_mode: A boolean value indicating whether to use Mailjet's sandbox mode. When set to true, emails will not be sent and will only be logged for testing purposes.
10. test_mode: A boolean value indicating whether to use Mailjet's test mode. When set to true, emails will be sent but will not be charged to your account.

These configuration options can be set in your Rails application's config/application.rb file or in an initializer file. For example, to set the api_key and secret_key options, you can add the following lines to your config/application.rb file:

config.action_mailer.mailjet_settings = {
  api_key: 'YOUR_API_KEY',
  secret_key: 'YOUR_SECRET_KEY'
}
