Two different WhatsApp features both promise to reach a lot of people at once, and it’s easy to assume they’re the same thing with different names. They’re not — they solve different problems, and using the wrong one for a job usually shows up as low engagement or a message that never sends.
WhatsApp Channels
A public, one-way update feed. Anyone can follow a business’s channel without exchanging a message first, admins can post to unlimited followers, and followers can react but not reply in a normal chat. It’s closer to a public announcement feed than a conversation — good for brand updates, launches, and content a business wants broadly visible.
Broadcast campaigns (WhatsApp Business API)
The opposite shape: messages only go to people who’ve already opted in, using pre-approved templates in Meta’s Marketing/Utility/Authentication/Service categories, subject to the messaging tiers and quality rating covered in WhatsApp messaging tiers and quality rating. This is what marketing in WhatsApp actually covers — promotions, re-engagement, and announcements sent directly into an existing chat thread with someone who’s already said yes.
Which one to use for what
- Building broad awareness with no existing contact list — a Channel, since anyone can follow without prior opt-in.
- Reaching people who already messaged the business — a broadcast campaign, since it lands directly in their existing chat and supports two-way follow-up.
- A promotion that needs a reply or a booking action — broadcast, not a Channel, since Channel followers can’t respond in-thread.
Why this is different from the existing marketing post
Marketing in WhatsApp is about running opted-in broadcast campaigns well. This is the layer above it — deciding which mechanism (Channel or broadcast) actually fits what’s being sent, before getting into campaign execution.
