WhatsApp campaigns setup needed
A WhatsApp campaign sends an approved template to an audience your team has saved, and reports what happened to each recipient. It is the one outbound channel where the message itself has to be approved before you may send it.
Needs:
the WhatsApp campaigns setting enabled, a WhatsApp Cloud inbox, and a template Meta approved.
How a WhatsApp campaign runs
An approved template, with its variables filled
Pick a template Meta has approved and map its variables to contact fields, so each recipient gets their own name, order number or date.
A saved audience
Send to a contact filter your team built and shares, rather than pasting a list into a box.
Delivery reporting per recipient
Sent, delivered, read and failed, per person, with the provider's error where a send failed.
Worth knowing
Three things have to be true before the first send: the WhatsApp campaigns setting enabled for your account, a WhatsApp Cloud inbox connected, and a template Meta has approved. Approval is Meta's decision and its timing is Meta's too.
