Every customer profile has one unified communications timeline.
Where
Customer profile → Activity tab → Communications.
What it shows
One chronological list, newest first, interleaving:
With the same filter pills as the Inbox: All · Portal · Text · Email · Requests. Click any row to open the thread.
What changed
The old Outbound / Support Inbox toggle on the customer profile is gone — every channel is two-way now, so there's a single timeline. The Review Safety card on the profile is unchanged and stays where it was.
Starting a new conversation from here
Click New Message at the top of the Communications timeline. Use the three-way Email / Text / Portal Message control, write, and send. The conversation appears in both this timeline and the main Inbox.
