Hotmail is a popular email service that many people use. It’s free and easy to use, and it has a feature called " Hotmail Addresses." If you have an address that you don’t want people to see, you can add it to your Hotmail account by clicking on the “Add an Address” button. Then, you’ll need to provide some information about the address. You can give the address a name, or you can just type it in as is. You can also choose to have your Hotmail account automatically fill in the addresses for you when someone sends you an email. Once you’ve added the address, it will be available in your “Inbox” and “Message History.” You can also view or delete the address at any time by clicking on the “Delete” button next to it.
