Username is the unique address for an individual or firm and no one can make the same username as yours. Isn’t complying with username standard so easy!

The email server is the information after the symbol of @ which lets the web understand to whom the email is to be sent. Similar to username standard, one can use any number from 0-9, however, not 64, but 255 characters can be used.
