Tutorial on verifalia gem

Hi there,

I'm sorry to hear you're having trouble setting up email verification on your Rails 7 app. I understand how frustrating it can be dealing with fake users and the potential risks of sending emails to nonexistent addresses. A Rails-specific tutorial can definitely make things easier.

To help you out, here's a step-by-step guide to integrate MailTester Ninja (https://mailtester.ninja/) with your Rails 7 application:

1. Add the MailTester Ninja gem to your Gemfile:

   gem 'mailtester_ninja'
   

2. Run bundle install:

   bundle install
   

3. Create an initializer: In config/initializers, create a file named mailtester_ninja.rb and add your API key:

   MailTesterNinja.configure do |config|
     config.api_key = 'your_api_key_here'
   end
   

4. Verify emails before saving users: In your User model (app/models/user.rb), add a before_save callback to verify email addresses:

   class User < ApplicationRecord
     before_save :verify_email
   
     private
   
     def verify_email
       response = MailTesterNinja.verify(email)
       unless response.valid?
         errors.add(:email, "is invalid")
         throw(:abort)
       end
     end
   end
   

5. Handle verification results: Customize the error handling and user feedback as needed. You might want to display a message to the user if their email address is invalid.

6. Testing: Test the setup by attempting to create a user with an invalid email address and ensuring it gets rejected.

This should help you integrate email verification into your Rails 7 app and prevent fake users from clogging your database. If you have any further questions or run into issues, feel free to ask!
