Channels live outside the chat list, in the Updates tab. Followers are invisible to each other, their phone numbers stay hidden from the admin, and the flow is strictly one-way: posts, reactions, and polls, but no replies or threads.
For a brand, a channel is a megaphone: product news, drops, and behind-the-scenes content pushed to everyone who follows, with no per-recipient cost and discovery through the in-app directory and shared links.
It complements rather than replaces opted-in marketing on the API: a channel cannot segment, personalize, or converse. Many brands use the channel for reach, and the one-to-one thread for conversion and support.
