How do I add labels to contacts?
Adding labels to contacts makes it easy to filter and search address books to find the people you need.
Select the contact you want to add a label to by checking the box next to their name in your contacts list.
Click “Apply label”. There are already labels for various import sources. If you would like to add a new label (or delete an existing one), click “Manage labels”
Give your new label a name (I’m calling mine “support”) and click the green “+” to save the label.
Finally, to save the label to your contact, just tick the box!
