Broadcast to VK community subscribers: who gets the message and how to build a list

November 5, 2026 · Command CHBT · Broadcasts, VK

You cannot send a private-message broadcast to all community subscribers: under VK rules a community writes only to those who wrote to it themselves or allowed messages. In CHBT a broadcast goes to contacts from the Contacts section — those who wrote to the community or tapped the bot’s button after it was connected. Sending: Broadcasts → New broadcast, the text, a tag in the To field, for example the “newsletter” consent tag, then Create a broadcast. The section is available from the Basic plan. Below — how to turn subscribers into recipients, how to send only to VK, what the name looks like and what delivery errors mean.

Who will receive the broadcast

Person	Gets the broadcast?
Subscribed to the community, never wrote	No — they are not in Contacts
Pressed “Allow messages” but wrote nothing	No — CHBT creates a contact only on a message or a button tap
Wrote to the community after the bot was connected	Yes, if they match the tags in To
Later forbade messages from the community	No — counted as an error

No service can bypass the VK rule. So the task is to give subscribers a reason to write to the community.

How to turn subscribers into recipients

A post with a code word. “Write SELECTION in the community messages — we will send new arrivals”. In CHBT create a flow with a Keywords trigger and the word “selection”, the first step — Action → Add a tag selection, then a reply with the selection.
The “Write a message” button in the community and a pinned post about what the conversation gives: a booking, a discount, an answer to a question.
A reply to a comment. A Studio code-word rule replies in the thread with a link to a conversation with the bot.
A poll or a quiz in community messages — a few questions with buttons, at the end a result and a tag by interest.

How to check: Contacts → Filter by tag selection shows how many people responded.

Consent to advertising broadcasts

A person who wrote “SELECTION” allowed an answer to their request but did not subscribe to weekly advertising. For regular advertising broadcasts, ask for consent in the same flow:

A Message: “Shall we send you new arrivals once a week?” with the buttons Yes and No.
Yes → Action → Add a tag newsletter.
A flow on the word “stop” → Remove a tag newsletter.

A ready flow with two consents and an opt-out is the Broadcast consent template, a breakdown — in the article how to build a broadcast list in a bot.

How to send a broadcast only to VK

The broadcast form does not choose a messenger: without tags it goes to all contacts in Telegram, MAX and VK. If the bot works in several messengers:

In the welcome flow add a Condition on the Channel field.
In the VK branch — Add a tag vk.
In the broadcast, put this tag in the To field.

Several tags in To work as “OR”: vk, newsletter will send both to everyone from VK and to everyone who agreed from other messengers. For “VK and consent” you need a combined tag from a flow — how to make it is covered in the article on broadcasts by segments.

The name in the text

In VK, CHBT takes the name from the profile — first and last name together. So “Hello, {{name}}!” turns into “Hello, Anna Petrova!”. Options:

write without addressing by name: “Good afternoon!”;
collect the name with a Data collection block of the Name type — the card will hold what the person called themselves;
fix the Name field in the contact card manually.

Besides the name, a broadcast supports {{phone}} and {{email}} if they are in the card. More — in the article on broadcast personalization.

Sending and checking

Write to the community from your account, then in Contacts open your card and add the test tag.
Broadcasts → New broadcast: Name for yourself, Message text, in To — test. Create a broadcast.
Check the message in VK: text, name, links, the reply word.
Create the same broadcast with the consent tag in To.

Text example: “Good afternoon! Next week master Olga has free slots: Tuesday and Thursday after 3 p.m. To book, write BOOK. To unsubscribe, write “stop””. A broadcast has no images or buttons — text only.

Result: the broadcast card shows recipients, delivered, errors and, if any, no channel.

The New broadcast form: Name, Message text, To, Scheduled start — The broadcast form: there is no messenger choice in it, recipients are set only by the To field.

Why some messages are not delivered

Reason	What happens	What to do
The person forbade messages from the community	Error, no retry	Nothing — you cannot write to them
The profile is deleted or blocked	Error	Nothing
The same text to the same person in a row	VK flood control, an error without retry	Do not duplicate a broadcast with the same text
Too many requests per second	CHBT retries after a pause	Nothing
The community key was rejected	Error; the channel is in Error, the owner gets an email	Channels → “⋯” → Change key
The community is disconnected in Channels	The no channel counter	Connect the community again

If several communities are connected to the bot, a contact gets the broadcast once — from the one they last wrote to. CHBT recognizes a reconnected community by its number and sends through the new connection. All counters — in the article why a bot broadcast is not delivered.
