With Yobi you can send and respond to Facebook Messenger messages in one app.
All customer conversations are viewable/searchable by your entire team. All past conversations are stored under each individual contact.
Mary may respond to an initial inquiry from your business Facebook page one day. Sara then responds to a follow up question a few days later. Both Mary and Sara will be able to view the entire conversation that the customer initiated both through your Facebook Page and all other forms of communication.
