When you create a guest list or upload your contacts into Evenesis, all your contacts will be automatically set as “N/A”. This could help you to differentiate the GROUPED list and UNGROUPED list. By default, your guest list will show a total number of all your contacts from all groups that you have. As a tip, before you upload your new contact, make sure all your existing guest lists in “N/A” are already grouped properly. This is to avoid your new contact lists get mixed with the existing one. Therefore, in the future you won’t have to face any problem to retrieve your old and new contact list.
