June 2026

Not everyone has the app. Everyone has a phone.

whoot. is built for the teams who live on voice — traders, operations centres, broadcast crews, security and emergency response. But the people you need to reach aren't always inside the app. A counterparty on an external desk. A contractor on site. A driver, a duty manager, an off-shift responder. They might never install anything — but every one of them can receive a text. SMS is the lowest common denominator that still works on every phone, in every pocket, right now.

So we made SMS a first-class citizen of the room. Give a room an SMS-enabled number and it becomes a real two-way text line. Reach people from it — send an alert, answer a reply — and when they text back, their message doesn't vanish into a separate inbox. It lands back in the same room, in the same timeline as your voice transcripts and chat, with the sender's number shown so you always know who you're talking to. The in-room chime fires, the same as any other message. It's a real conversation, and it happens where your team already is.

When you need to reach a lot of people, broadcast. Send from an alphanumeric Sender ID — your name in the "from" line instead of a number — for one-way notices that don't need a reply. Every Sender ID is checked against an anti-impersonation denylist first, so nobody can spoof a bank, a government body, or the emergency services from your account.

And when it's an emergency, SMS earns its keep. Fire an alert to a recipient list, ask a single question — "Are you safe?" — and watch the answers come back in real time. Re-ping only the people who haven't replied. Push an update to everyone, then a final all-clear. If someone replies that they're not OK, that text opens a one-to-one conversation with your team — and you can escalate straight to a voice call when a message isn't enough.

Throughout, every message in and out is recorded with its delivery status, STOP and START opt-outs are honoured automatically, and the whole comms log is built to be pulled for a Martyn's Law incident review. Reach anyone, keep the record, stay compliant — without leaving the room.

Everything you need to text and be texted back.

One number. Real conversations. Broadcast, alerts, and a full record — all in the room.

Two-Way, From Your Room's Number

Your room's number is a real, two-way SMS line — it sends and it receives
Replies route straight back into the same room — a conversation, not a dead end
The person on the other end just texts back; no app, account, or link on their side

It Lands in the Timeline

Inbound texts appear in the room feed alongside voice transcripts and chat
The sender shows by their phone number — never an anonymous "external party"
The same in-room notification fires, so nobody misses an incoming reply

Branded Broadcast

Send from an alphanumeric Sender ID — your name, not a number
Ideal for one-way notices where you don't expect a reply
Screened against an anti-impersonation denylist before it can go live

Emergency Alerts, Answered

Broadcast to a recipient list and ask a simple question — "Are you safe?"
Re-ping only the people who haven't replied yet — no spamming responders
Push live updates and a final all-clear, with the ack roster updating in real time

Reply NO, Get a Person

A distress reply opens a one-to-one conversation with your team
Operators answer from the room's number — the thread stays connected
Escalate straight to a voice call when a text isn't enough

Consent & Opt-Out, Built In

STOP and START are honoured automatically and mirrored across your lists
Opt-in signup links let people add themselves to an alert list
Opted-out numbers are skipped on every future send — fail-safe by default

Reach anyone.
Hear them back.
No app required.

Logged & Compliant

Every text, on the record.

A text message is a communication like any other — and in a regulated or safety-critical operation, it has to be accounted for. Every SMS your team sends or receives is captured with its full delivery status and kept in a tenant-wide comms log you can filter and export — built specifically for Martyn's Law incident review. Sender identity is recorded on every inbound message, opt-outs are honoured automatically, and Sender IDs are screened so no one can impersonate a trusted institution from your account.

Every SMS, inbound and outbound, recorded with full delivery status — queued, sent, delivered, or failed
A tenant-wide, filterable comms log built for Martyn's Law incident review and evidence
Sender identity captured on every inbound message — no anonymous texts reaching your rooms
STOP/START opt-out handled in-house and synced with carrier opt-outs
Alphanumeric Sender IDs screened against a banks/government/emergency-services denylist
Inbound rate-limited per sender and per number — nothing is lost, even when throttled
Per-number sender allowlists and geo-restriction for tighter control on who can text in
