How to hide your Gmail address — Stop unwanted emails from ... Hiding your Gmail address, or masking it behind a false address, can prevent pesky spam from overloading your inbox. Here are a few available methods to try.
Method 1: Create an Alias
One way to hide your Gmail address is to create an alias. This allows you to use a different email address for different purposes, keeping your main Gmail address private. You can set up an alias in your Gmail settings and use it to sign up for newsletters, online services, or any other situation where you don't want to give out your primary email.
Method 2: Use a Disposable Email Address
Another option is to use a disposable email address service. These services provide you with a temporary email address that forwards messages to your main Gmail account. Once you're done with the alias, you can simply delete it, preventing further emails from reaching your inbox. This is a great way to protect your primary email address from spam.
