how do you make the email account like: dumb51@google.com

i want to know what me email address is and to make my own free

Sorry, not completely sure what you’re suggesting, eM Client does not allow you to create a new email account, in order to create a new gmail account (whatever@gmail.com) visit http://mail.google.com/ , @google.com email addresses are most likely reserved for employees of the company only.

no i mean by the email address like your name and then your company

You might have to contact a mail service vendor, for example… Gmail. You can only setup an existing account with eM Client, to do so you just use your credentials to authenticate with the application and the application should automatically setup the account’s details based on your server’s auto-discover preferences.
