Settings → Communications has three tabs.Messaging
Connect WhatsApp uses your WhatsApp Business number. You continue with Facebook, then come back here. Status is Not connected, Pending review, Needs attention, or Ready. While Meta is still reviewing templates, the number can be connected and sending stays off. Disconnect stops outbound WhatsApp until you connect again. Customer replies show in Inbox when they match a customer. Connecting WhatsApp does not turn reminders on. Visit reminders are under Jobs. Estimate and invoice sends use WhatsApp only when you choose that channel on the send. Facebook Messenger and Instagram can use the same inbox. Each has its own connect and disconnect.Email appearance
This changes how customer emails look. It does not change the words. Wording stays under Jobs, Estimates, and Invoices.
Blank colours fall back to the default theme. Preview shows the email before you save.
