README

        
This is an example rails app on how to configure and use the [Resend Rails SDK](https://github.com/drish/resend-ruby) with Rails Action Mailer

# Setup

Add the gem to your Gemfile:

```ruby

# Gemfile

gem "resend"

```

Create a `/config/initializers/mailer.rb` file and add the following configuration line.

```

Resend.api_key = ENV['RESEND_API_KEY']

```

Add these lines of code into your environment config file.

```rb

# Setup resend as the email method

config.action_mailer.delivery_method = :resend

```

Checkout the [Rails example app with SMTP setup](https://github.com/resendlabs/resend-rails-smtp-example) for SMTP support example.

Create your mailer class

```ruby

# /app/mailers/user_mailer.rb

class UserMailer < ApplicationMailer

  default from: '[email protected]' # this domain must be verified with Resend

  def welcome_email

    @user = params[:user]

    attachments["invoice.pdf"] = File.read(Rails.root.join("resources","invoice.pdf"))

    @url  = "http://example.com/login"

    mail(

      to: ["[email protected]"],

      cc: ["[email protected]"],

      bcc: ["[email protected]"],

      reply_to: "[email protected]",

      subject: "Hello from Rails",

    )

  end

end

```

Create your `ERB Template` for `UserMailer`

```ruby

# /app/views/welcome_email.html.erb

  

    

  

  

    
Welcome to example.com, <%= @user.name %>

    


      You have successfully signed up to example.com,

    

    


      To login to the site, just follow this link: <%= @url %>.

    

    
Thanks for joining and have a great day!

  


```

Now you can send your emails, lets send it using Rails console.

```sh

bundle exec rails c

```

Initialize your `UserMailer` class, this should return a `UserMailer` instance.

```ruby

u = User.new name: "derich"

mailer = UserMailer.with(user: u).welcome_email

# => #, , , ...

```

You can now send emails with:

```ruby

mailer.deliver_now!

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

```
