E-mail is one of the top methods of communication, so having a personalised and memorable e-mail address is important. It can be hard to know what e-mail address to go for, though, as over 4 million e-mail addresses are currently in use, and it can be difficult to find out what is still available. Here is the easiest way to see if the address you want is in use.
Select "Email Dossier" from the list. This is usually the third option down from the top.
Enter the email address you would like to check in the box, in full. For example, firstname.lastname@example.org.
Scroll down to view the "Confidence Level," which should be a number or letter.
Click "More Info," at the end of the "Confidence Level" paragraph. This will load a table, which explains each rating. Look at the row for the rating your desired address received, and see if it is in use. The most common rating is "3," which is in use.
Try adding numbers to the end of your desired address if it is taken.
