You can add another address/alias to your account at any time from the Home page.
To do this, click on the "Add An Address" button.
There, select a username. This is the part before the @ sign in an email address.
Then choose whether you want to use a domain that Pobox owns, or one of your own domains. Select the domain name you want to use from the drop-down that appears.
Then you can choose whether you want to add this address to your own account, or a new account. If the address is for you, and should use your account settings and password, choose "this account". If it's for someone else, who should have their own account, password and settings choose "a new account".
Pobox Basic accounts will have the new address added immediately when you click "This Account". Pobox Plus and Mailstore accounts will ask you where you would like mail for that address to be sent.
Next, you will need to fill out the information for where mail to that address should be delivered. If you have a Pobox Basic account, you will only be able to deliver it to your existing delivery group. If you have a Pobox Plus or Mailstore account, you will be ale to deliver mail to a new delivery group. Finally, if you have a Mailstore account, you would also be able to deliver mail to your Mailstore Inbox.
If you have an address on your account that you already want to deliver mail to, select the checkbox next to that address. If you have a new address you with to deliver mail to, type in the full address in the check box, then click on the 'Add' button next to the address.
To save the changes, click on the 'Add Address' button at the bottom of the page.
