Send emails using Rails with SMTP

Send email using Rails Action Mailer

Then create a UserMailer class definition.

app/mailers/user_mailer.rb

class UserMailer < ApplicationMailer
  default from: 'Acme <onboarding@resend.dev>' # this domain must be verified with Resend
  def welcome_email
    @user = params[:user]
    @url = 'http://example.com/login'
    mail(to: ["delivered@resend.dev"], subject: 'hello world')
  end
end

And create your ERB email template.

app/views/user_mailer/welcome_email.html.erb

<!doctype html>
<html>
  <head>
    <meta content="text/html; charset=UTF-8" http-equiv="Content-Type" />
  </head>
  <body>
    <h1>Welcome to example.com, <%= @user.name %></h1>
    <p>You have successfully signed up to example.com,</p>
    <p>To log in to the site, just follow this link: <%= @url %>.</p>
    <p>Thanks for joining and have a great day!</p>
  </body>
</html>

Initialize your UserMailer class. This returns an ActionMailer::MessageDelivery instance.

u = User.new name: "derich"
mailer = UserMailer.with(user: u).welcome_email

# => #<ActionMailer::MessageDelivery:153700, @mail_message=#<Mail::Message...>, @processed_mailer=...>

Finally, you can now send emails using the deliver_now! method:

mailer.deliver_now!

# => {:id=>"a193c81e-9ac5-4708-a569-5caf14220539", :from=>....}
