In this tutorial we’re going to see how to validate email address on G Suite account using a simple api. But before I get into the details let me explain what happens when you receive an email address: usually your email provider creates a message that contains the email address. But if you are using G Suite then your email provider may have a different method to authenticate your email address. You can do this yourself but it’s not that easy, so I decided to make an awesome tutorial that will show you how to do it without even touching any code.
