How to Make an Announcement-Only Group Chat Where Only Admins Can Send: WhatsApp, Telegram, Signal and Nadeemi
Part of: Family privacy online: photos, children and quieter networksChecked against each app's own announcements and help pages, 6 November 2026. Menus move; check the date.
Every school class, sports team, building committee and extended family eventually has the same problem: the one message that matters ("pickup moves to 2 pm tomorrow") is buried under 80 replies of "thank you 🙏". The fix is an announcement-only group: everyone can read, only admins can send.
Short answer: WhatsApp: Group info > Group settings > Send messages > Only admins. Telegram: use a channel for one-way news, or in a group set Permissions > Send messages off for members. Signal: Group settings > Permissions > Send messages > Only admins. In all three, members keep reading, and admins can switch it back at any time.
When an announcement-only group is the right tool
- School classes and clubs: dates, pickup changes, what to bring.
- Mosques, churches and community centres: prayer times, events, volunteering.
- Buildings and neighbourhoods: water cuts, meetings, deliveries.
- Big families: one "family news" group for weddings, births and travel, separate from the chatty one.
The setting in each app (checked 6 Nov 2026)
| App | Where | Members can still… | Alternative |
|---|---|---|---|
| Group info > Group settings > Send messages > Only admins | Read; past messages stay | Communities with an announcement group; Channels (public, one-way) | |
| Telegram | Group: Permissions > Send messages (off for members) | Read; admins can allow reactions | Channels: only admins post, unlimited subscribers |
| Signal | Group settings > Permissions > Send messages > Only admins | Read; members see a note instead of the message box | — |
| Nadeemi | Group info > "Only admins can send messages" | Read and react | Circles with "Only admins can post" (members still comment) |

Open the group > Group info > Group settings > Send messages, choose Only admins. Members see a short note in place of the message box; nothing they sent before is affected. WhatsApp introduced this in 2018 for schools, community centres and non-profits. For many groups under one roof, a Community has its own announcement group.
Telegram
Telegram has two tools. A channel is one-way by design: only admins post, and anyone with the link can follow. In a normal group, admins can turn off Send messages for members in the group's permissions. Note that Telegram groups and channels are not end-to-end encrypted.
Signal
Group settings > Permissions > Send messages, choose Only admins. Members get a note at the bottom of the chat that only admins can send. Signal encrypts groups end to end by default.
Five rules for an announcement group people don't mute
- One topic per message, with the date and time in the first line.
- Pin the important one (most apps let admins pin a message).
- Give people a place to ask: a second, open group, or "reply to me directly".
- Two or three admins, so nothing waits when one is busy.
- Use disappearing messages for routine notices, so the group stays short. See disappearing messages explained.
How Nadeemi does it
Nadeemi is the app we build, so weigh this section accordingly. In a group chat (up to 50 people), admins can switch on "Only admins can send messages": members keep reading and reacting, our server refuses messages from members, and members' devices also ignore them, so a modified app can't get around it. Since 6 November 2026, Circles (private groups of up to 200 with a feed) have "Only admins can post": members can still comment and react, which suits a class or a community notice board. Admins can add a group description that shows under the group name, pin a message, create invite links that expire or can be revoked, show them as a QR code, and new members can scan the code inside the app to join. Nobody needs a phone number, so parents and neighbours never see each other's numbers. Group chats are encrypted on your device with MLS in the beta; we label them "end-to-end encryption coming" until an independent audit is published.
FAQ
How do I make a WhatsApp group where only admins can send messages? Group info > Group settings > Send messages > Only admins. Switch back to "All participants" at any time.
What is the difference between a Telegram group and a channel? In a channel only admins post and followers read. In a group everyone can talk unless admins restrict sending in the group's permissions.
Can members still react in an announcement-only group? It depends on the app. In Nadeemi members can react to messages in admins-only groups, and comment on posts in admins-only Circles.
Will members know I changed the setting? Yes. Apps show members a note that only admins can send, in place of the message box.
Is an announcement-only group private? It is as private as the app: WhatsApp and Signal groups are end-to-end encrypted; Telegram groups and channels are not. In phone-number apps, members can still see each other's numbers.
