The first time I posted to a channel with a few hundred subscribers, I sat staring at the view counter not understanding what was happening. On a social network, a post of mine reached an unpredictable fraction of my followers. Here the number climbed steadily towards the subscriber count and stopped. There was nothing to decode. It had simply reached everyone.
That contrast is the whole thesis of this article, so it is worth understanding properly before drawing hasty conclusions.
A feed rations; a channel delivers
A platform with an algorithmic feed has a problem to solve: more content is published than fits in its users' attention. Its answer is to rank. A system decides, for each person and each moment, what deserves to appear. Someone following you is a strong signal in that calculation, but it is one signal among many, and it guarantees nothing.
A broadcast channel does not have that problem, because there is no feed to rank. You publish and the message is sent, in chronological order, to the subscriber list. There is no auction, no implicit bidding against other advertisers, and no penalty for posting an external link. Distribution is not a decision the platform makes: it is a mechanical consequence of someone having subscribed.
A channel is much closer to a mailing list than to a social profile.
That comparison is the most useful one I know. If you come from email marketing, almost all your instincts will work here: the list is yours, delivery happens, frequency is your decision with consequences, and a neglected list degrades on its own. If you come from social media, you will have some unlearning to do.
What you gain
- Complete, ordered delivery. You publish once and the message sits in the channel, in its chronological place, for everyone. Nobody sees a different version of the channel.
- Notification by default. Unless a subscriber has muted the channel, a new post generates a notification. That is a level of access to attention a feed does not give you.
- Public view counts. Each channel post shows how many times it was viewed, and anyone who visits can see that number. It is unusual transparency: it lets you judge the real activity of someone else's channel before deciding whether you want to appear in it.
- No subscriber ceiling. A channel has no member cap the way groups do, so the structure you set up early still serves you later.
- External links cost you nothing. You can link outward without reducing the message's distribution, simply because there is no ranking system that cares.
What you lose
This is the part omitted from most articles about the wonders of broadcast messaging, and it is the part that determines whether this is useful to you.
- There is no discovery. None. There is no system putting your channel in front of people who did not look for it. There is no equivalent of an explore tab, no recommendations, no video that goes viral by itself. Every subscriber arrived because you brought them from somewhere.
- Growth is always deliberate and usually paid. Because there is no discovery, subscribers come from your other channels, from third-party recommendations, from deals with other channels, or from advertising. All of those take effort or money. There is no free, automatic route.
- Delivered is not read. Muting a channel takes two taps and people do it readily, especially when a channel posts too much. Guaranteed delivery is real; guaranteed attention does not exist on any platform.
- You see very little of your audience. You know how many subscribers you have and how many views each post got. You do not know who saw what. I cover this in detail in the article on measurement, because that is where expectations break hardest.
There is a partial exception to the lack of discovery: forwarding. When someone forwards one of your posts to another chat, the forwarded message keeps a reference back to the originating channel, so it acts as a recommendation with a built-in link. It is the only propagation mechanism you get for free, and it explains why posts written to be forwarded — self-contained, with enough context to make sense outside the channel — perform differently from posts that assume you were already there.
So what is it actually good for?
Put the two lists together and a fairly sharp profile emerges. Broadcast messaging is strong where retaining and re-reaching an audience you already have matters, and weak where acquiring one does.
It works well for:
- Announcements people actually want at the moment they happen.
- Regular publishing to an audience that already chose you and wants continuity.
- Content that is better read in order.
- Reducing dependence on platforms where someone else decides your reach.
It works badly for:
- Getting known from a standing start.
- Impulse reach, the "I need a lot of people this week" kind.
- Any plan that depends on something spreading by itself.
The healthy way to frame it, I think, is as the second step of something: first you acquire the person somewhere that does have discovery, then you move them to a channel so you never have to pay to reach them again. Using it as the first step is precisely the job it is worst designed for.
If that fits what you need, the logical next step is understanding how traffic is bought inside the platform itself. And there is a rule there that catches almost everyone out the first time: I cover it in the article on the ad platform.

- Official documentation, Official blog — announcements of product changes.
The judgements about what it is and is not good for are mine, and I present them as what they are: a view, not a fact.
