- Go to Recipients and Lists, and open the contact list you want to add the contact to.
- Click on New contact and enter the contacts details.
(Only an e-mail address OR text message number is mandatory). - Save your contact by clicking "Create contact".
If the contact already exists in this contact list, the contact will not be added. This makes it impossible to have duplicates in contact lists (where the e-mail address or text message number is unique).
