Your customers already message you on WhatsApp, and you want to tell them about new stock. Broadcast lists stop at 256 recipients and only reach people who saved your number. Status disappears after 24 hours. Messaging everyone one by one costs an evening of copy-paste and risks a spam report from someone who forgot who you are.

WhatsApp Channels fill that gap: one post reaches unlimited followers, nobody needs to save your number, and followers never see your phone. But there are quirks most people discover after launch: no comments, notifications off by default, and a directory that sends almost nobody to a small business. Below: setup, what to post, where followers actually come from and when your effort is better spent elsewhere.

The key idea: a channel is a shop window, not a conversation. Followers can’t reply to a post with text. So every post that should trigger an action needs a wa.me link into your private chat, where labels and quick replies take over. That side of the setup is covered in the WhatsApp Business guide.

A market reality check: WhatsApp is the default way to talk to a business in India, Brazil, Indonesia, Mexico, Spain and much of Europe and Africa. In the US, where SMS and iMessage dominate, a channel is a secondary touchpoint at best.

Setup in 15 minutes

  1. Create the channel. Updates tab → ”+” → “New channel”. Create it from the number your business runs on and add a teammate as admin right away: a channel can have up to 16 admins, and losing one phone should not mean losing the channel.
  2. Name it like your storefront plus a city or niche. “Bean Lab Lisbon — coffee drops and deals”, not “Bean Lab News”. The directory searches by name, and the city helps people nearby find you.
  3. Write a description that answers three questions: what will be posted, how often, and where to send questions. Example: “New roasts and weekly deals. 3–4 posts a week, no spam. Order: wa.me/351912345678”.
  4. Use the same avatar as your WhatsApp Business profile and Instagram.
  5. Grab the link and QR code. In channel info, tap “Share”: the whatsapp.com/channel/... link goes into your social bios, the QR code onto the counter and packaging.
  6. Test from another phone. Follow it yourself and check it shows up in search.

For your first post: notifications are off for followers by default, so posts quietly land in their Updates tab. Ask people to tap the bell and give them a reason: “Turn on notifications — we post drops here before Instagram, and popular sizes go within an hour.”

What to post: formats and examples

Channels support text, photos, videos, voice messages, stickers, links and polls with up to 12 options. You can edit a post for 30 days, after which it is removed from WhatsApp servers. Standard formatting works: *bold*, _italic_, lists and > quotes.

A sustainable rhythm for a small business is 3–5 posts a week. Ten posts a day means an ever-growing unread badge in Updates, then an unfollow.

FormatWhyExample
New stockThe main reason to follow”New Balance 530 just landed, sizes 6–11, three colourways in the photos. Reserve a pair: wa.me/447700900123?text=530”
PollEngagement plus demand data”Which cake joins the December menu? Carrot / Tiramisu / Cheesecake. The winner is 15% off in week one”
Owner voice noteTrust and a human face30–60 seconds on why you switched suppliers and what changes in the taste
Limited offerSales today”3 slots left with Maya on Saturday. Message SATURDAY: wa.me/…”
Useful tipA reason not to unfollow”How to store beans after opening: 3 rules and the mistake everyone makes”
Behind the scenesKeeps the channel aliveUnloading a delivery, a bouquet being built, a new team member

Notice the ?text=530 and ?text=SATURDAY links. A code word tells you which post brought the person in, and it is the only honest way to measure a channel: reactions feel nice, but revenue comes from people who message you.

If you already run Instagram or a Telegram channel, don’t write from scratch. Take the same post, cut it to 3–5 lines and add the chat link. The approach is in our guide to content repurposing.

Where followers actually come from

The WhatsApp directory filters by country and shows popular, new and most active channels. A new local business gets very little from it: those slots go to media, sports clubs and celebrities. Your followers come from touchpoints you already own.

  1. Existing customers in chats. Put the channel link into your greeting and away messages and create a /channel quick reply — a nudge for people already talking to you, not a blast.
  2. Status. Once a week, share your best channel post in Status with the link. Status reaches people who saved your number, which is your warmest audience.
  3. Offline. A QR code on receipts, the counter and bags, with a clear benefit: “Follow our channel — hear about new stock and deals first.” Without a benefit, almost nobody scans.
  4. Bios and signatures. Instagram bio, Telegram channel description, email signature, the Contact page of your site.
  5. Forwards and collabs. A forwarded post shows the channel name, and people can follow in one tap. Team up with a neighbouring niche: the coffee shop forwards the bakery’s post and vice versa.
  6. Paid options. Click-to-WhatsApp ads open a chat, not a channel. Meta is gradually rolling out promoted channels in the directory and paid channel subscriptions, but availability varies by country, so check your channel settings before you put it in the plan.

Do the maths on your ceiling: at 20–30 conversations a day, 600–900 people pass through your chats every month. Even if one in five follows, that’s over a hundred followers a month with zero ad spend. Without the link at every touchpoint, a channel can sit at twenty friends for months.

How to tell whether it works

Built-in stats are thin: follower count, reactions, poll votes. Once a week, pull three numbers together:

  • Follower growth for the week and where it came from (a spike on the day you put the QR on the counter is a clear signal).
  • Messages with code words from your posts — how many people messaged you after a post.
  • Deals from those messages. A “from channel” label in WhatsApp Business handles this without a CRM.

A month without a single code-word message means the posts give no reason to reach out. Add price, stock left, a deadline.

When a WhatsApp channel won’t work

  • Your audience lives on Telegram. In Central Asia, Eastern Europe and plenty of niches elsewhere, a Telegram channel gives you more: comments, view counts on every post, search, scheduled posts. See our guide on growing a Telegram channel.
  • You need conversation, not broadcasting. A customer club, discussions, peer help — that’s a group or a community, not a channel.
  • There’s no rhythm. One post a month is worse than no channel: people forget why they followed.
  • You want full automation. Meta has no official API for posting to channels. Services that promise WhatsApp channel autoposting usually emulate the web client, which puts at risk the very number your customer conversations depend on.
  • You expect new customers from nowhere. A channel retains and reactivates people who already know you. New ones come from ads, Instagram, maps and word of mouth.

Repost21 doesn’t publish to WhatsApp, but it can take the time-consuming part off your plate: the Idea Feed pulls topics from your sources, Luna trims an Instagram or Telegram post into a channel-sized version with a chat link, and your main platforms autopost from the content calendar.
