Sending Emails Made Easy with Rails Active Mailer

Rails Active Mailer is a powerful framework for sending emails from your Ruby on Rails application. With Active Mailer, you can send transactional emails, newsletters, and other types of email communications to your users.

Here’s an example of how Rails Active Mailer works:

Let’s say you have a Rails application and want to send a welcome email to a new user who just signed up. With Active Mailer, you can easily create an email template that includes a personalized greeting, introduction to your app, and any other relevant information you want to share with your user.

Here’s an example of how to set up Rails Active Mailer:

1. Install Rails Active Mailer by adding it to your Gemfile and running bundle install.
2. Create a new mailer by running the command rails generate mailer MyMailer. This will create a new file called my_mailer.rb in the app/mailers directory.
3. Open the my_mailer.rb file and define your email template. For example:
   
   
   
   

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

In this example, the welcome_email method defines the email template and sets the recipient’s email address and email subject.

4. In your controller, call the MyMailer.welcome_email(user).deliver_later method to send the email. For example:

class UsersController < ApplicationController
  def create
    @user = User.create(user_params)
    MyMailer.welcome_email(@user).deliver_later
  end
end

With just a few lines of code, you can send a personalized email to your user.

Rails Active Mailer also provides many other features, such as support for email attachments, inline images, and custom email headers. With its easy-to-use interface and powerful features, Rails Active Mailer is an essential framework for any Ruby on Rails developer looking to simplify email communication in their application.

In conclusion, Rails Active Mailer is a powerful and flexible framework for sending emails from your Rails application. With its straightforward setup process and powerful features, you can easily send transactional emails, newsletters, and other types of email communications to your users.
