To add or remove existing contacts to one of your existing lists, or a new list, first look up the email addresses by searching or clicking into the list they’re already on.
Add Contacts to a List
Manually select each email address you want to add, then go to Bulk Actions > Add Selected to List:
Then, choose whether you want to add to an existing list or Create a New List:
Remove Contacts from a List:
Manually select each email address you want to add, then go to Bulk Actions > Remove from List. NOTE: This will only display as an option if all the contacts you’ve chosen are already assigned to a list. This also only clears contacts from the list, it DOES NOT delete them. Clearing simply removes them from the list but leaves them in your overall database.
