When searching for an existing Contact, it is important to use the correct search field.
The first step is to select the Contacts tab (to the right of the Messages tab). Then, enter any of the Contact's contact information within the search field.
You may search for the Contact's name, phone number, or any details within the Business Field.
We recently added Tags as well! Search for any one of your Tags to view all Contacts associated with the assigned Tag. This makes creating Groups even easier.
