Ruby on Rails SendGrid step by step setup and configuration

Integrating SendGrid into a Ruby on Rails project is a straightforward process that involves configuring the SendGrid API key and using the SendGrid API to send emails. Here are the steps to integrate SendGrid into a Ruby on Rails project:

1. Install the SendGrid Ruby Gem: The first step is to install the SendGrid Ruby Gem, which provides a Ruby wrapper for the SendGrid API. You can install the gem by adding it to your Gemfile and running bundle install:

# Gemfile
gem 'sendgrid-ruby'

2. Configure the SendGrid API key: Next, you need to configure the SendGrid API key in your Rails application. You can do this by creating an initializer file, such as config/initializers/sendgrid.rb, and adding the following code:

# config/initializers/sendgrid.rb
require 'sendgrid-ruby'

SendGrid::API_KEY = ENV['SENDGRID_API_KEY']

Make sure to replace ENV['SENDGRID_API_KEY'] with your actual SendGrid API key, which you can obtain from your SendGrid account dashboard.

3. Create an email template: Before you can send emails using SendGrid, you need to create an email template. You can do this by creating a new view file, such as app/views/user_mailer/welcome.html.erb, and adding the HTML and CSS for your email template. Here's an example:

<!-- app/views/user_mailer/welcome.html.erb -->
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Welcome to My App</title>
  </head>
  <body>
    <h1>Welcome to My App</h1>
    <p>Hi <%= @user.name %>,</p>
    <p>Thank you for signing up for My App. We're excited to have you on board!</p>
  </body>
</html>

4. Send the email using the SendGrid API: Finally, you can send the email using the SendGrid API. You can do this by creating a new mailer class, such as app/mailers/user_mailer.rb, and adding the following code:

# app/mailers/user_mailer.rb
class UserMailer < ApplicationMailer
  def welcome_email(user)
    @user = user
    mail(to: @user.email, subject: 'Welcome to My App')
  end
end

This code defines a new mailer class called UserMailer with a method called welcome_email that takes a user object as an argument. The method sets the @user instance variable and calls the mail method to send the email to the user's email address with the subject "Welcome to My App". To send the email, you can call the deliver_now method on the mailer object:

UserMailer.welcome_email(@user).deliver_now

Overall, integrating SendGrid into a Ruby on Rails project is a simple process that involves configuring the API key, creating an email template, and using the SendGrid API to send emails.
