To add a new address:

Select the group you want to add the address to from the list of groups (the default is "Default Group").

Choose Addresses > New Address or click the Add (+) button at the bottom of the address table.

Type the email address. Important: Direct Mail splits up email addresses into a user portion and a domain portion. The user part is everything before the '@' symbol, domain is everything after. For example, if the email address was johndoe@email.net, the user portion would be "johndoe" and the domain portion would be "email.net".
