An alternative to SMS alerts
Everything below rests on one rule: a channel asks, and the phone decides. What arrives is guaranteed; how loudly it arrives is not, and any page that told you otherwise was selling.
Nothing that could identify anybody
Subscribing needs no account, no email address and no phone number. What a subscription actually holds is a random identifier the app generated, a platform, an app version, a language and a time zone — coarse enough that hundreds of millions of people share one. There is no name, no contact detail, no advertising identifier and no location, and there is no export that would let an operator build one. You cannot leak a list you never collected.
Priced per channel, so the quiet one stays free
A school’s internal staff channel and its public parent channel are not the same size and are not charged the same. Each channel carries its own plan and everything lands on one invoice per workspace. The free tier is a real tier rather than a trial: no card, no countdown. Alerts are metered by how many subscribers an alert could reach when you committed to sending it, and going over bills the excess rather than silencing the channel — an alert that fails to leave because of a billing limit is the wrong way for this product to fail.
Four subscribers or four million, same message
Sending does not fan out into per-recipient work: an alert is written once and each phone asks for what it has not seen. That is why the cost and the speed do not change with the size of the audience, why there is no queue to drain and no per-message price to negotiate. It is also the reason the honest-numbers section reads the way it does — the same design that makes it cheap is what makes a delivery receipt impossible.
Questions, answered plainly
What do you collect about somebody who subscribes?
A random identifier the app generated, a push token, the platform, the app version, the language and the time zone. No name, no email address, no phone number, no location, and no advertising identifier. Subscribing needs no account at all.
What happens if we go over the plan?
Extra alerts are billed at the metered rate rather than being refused: an alert that does not go out because of a billing limit is the wrong failure. Going over the subscriber cap is different — new subscriptions are queued, receive nothing, are told so, and are released oldest first when the cap rises.
Does it get slower or more expensive as we grow?
No. An alert is written once and each device asks for what it has not seen, so four million subscribers cost the same to send to as four. Your plan caps how many subscribers a channel may have, but the send itself does not change shape.
Do subscribers need an account?
No. They install the app, subscribe to a handle, and that is the whole of it. Only the person running the channel signs up for anything.
Say it once. Every subscribed phone gets it.
Free up to 100 subscribers, no card to start, and the handle is yours permanently.
