Adding users depends on the type of account you have with us. There are two types of accounts, Business Accounts and Home Office Accounts. For both account type, you must be logged into your account.
Home Office Accounts
This type of account allows for up to 9 users (Email Addresses) that can use your account for sending faxes. Once logged in, navigate to "Settings" and then "Sending Faxes", in the section labelled "Authorized Email Addresses" enter one Email address in each spot from 2 through 9. The first spot will always be the Login Email address.

Business Accounts
With Business accounts you are allowed an unlimited number of "Outbound Only" users. If you have 9 or less you can use the same method of adding users as above by entering up to 9 users (Email Addresses) by navigate to "Settings" and then "Sending Faxes". In the section labelled "Authorized Email Addresses" enter one Email address in each spot from 2 through 9. The first spot will always be the Login Email address just as shown above.
If you have more than 9 users for sending faxes, then it is better to administer them by navigating to "My Account" and then "User Administration". This screen will display all your registered users. To add a user simply click on the "Add User" button (note you can also delete users here by clicking on the Delete icon).
Once you have selected the type of user fill in the required fields and click on the "Create New User" button.
