Ruby on Rails Amazon Simple Email Service step by step setup and configuration

Integrating Amazon Simple Email Service (SES) into a Ruby on Rails project is a straightforward process that involves configuring your application to use the SES API and setting up email templates. Here are the steps to follow:

1. Set up an Amazon SES account: Before you can start sending emails with SES, you need to set up an AWS account and enable SES. Once you have done this, you will need to verify your email address or domain to ensure that your emails are delivered successfully.

2. Configure your Rails application: To configure your Rails application to use SES, you will need to add the AWS SDK for Ruby gem to your Gemfile and configure your AWS credentials. Here is an example of how to configure your credentials:

# config/initializers/aws.rb
Aws.config.update({
  region: 'us-west-2',
  credentials: Aws::Credentials.new('ACCESS_KEY_ID', 'SECRET_ACCESS_KEY')
})

3. Create an email template: To send emails with SES, you will need to create an email template that defines the content and structure of your emails. You can create email templates using the SES console or the SES API. Here is an example of how to create an email template using the SES API:

# app/mailers/user_mailer.rb
class UserMailer < ApplicationMailer
  def welcome_email(user)
    @user = user
    @url  = 'http://example.com/login'
    template_data = {
      name: 'welcome_email',
      subject_part: 'Welcome to Example.com',
      text_part: 'Hello <%= @user.name %>! Welcome to Example.com!',
      html_part: '<h1>Hello <%= @user.name %>!</h1><p>Welcome to Example.com!</p>'
    }
    resp = Aws::SES::Client.new.send_templated_email({
      source: 'support@example.com',
      destination: {
        to_addresses: [@user.email]
      },
      template: template_data[:name],
      template_data: {
        subject: template_data[:subject_part],
        text: template_data[:text_part],
        html: template_data[:html_part]
      }
    })
  end
end

4. Send emails: Once you have configured your application and created your email template, you can start sending emails using the SES API. Here is an example of how to send a welcome email to a new user:

# app/controllers/users_controller.rb
class UsersController < ApplicationController
  def create
    @user = User.new(user_params)
    if @user.save
      UserMailer.welcome_email(@user).deliver_now
      redirect_to @user
    else
      render 'new'
    end
  end
end

By following these steps, you can easily integrate Amazon SES into your Ruby on Rails project and start sending transactional emails to your users.

5. http_open_timeout: The amount of time in seconds to wait for a connection to be opened when making SES API requests. This option is optional and can be used to customize the timeout behavior of your application.

6. http_read_timeout: The amount of time in seconds to wait for a response to be received when making SES API requests. This option is optional and can be used to customize the timeout behavior of your application.

7. http_idle_timeout: The amount of time in seconds to wait for a connection to become idle before closing it when making SES API requests. This option is optional and can be used to customize the connection behavior of your application.

8. http_continue_timeout: The amount of time in seconds to wait for a "continue" response from the server when making SES API requests. This option is optional and can be used to customize the behavior of your application when sending large messages.

9. http_wire_trace: A boolean value that determines whether to enable wire tracing for SES API requests. This option is optional and can be used to debug issues with SES API requests.
