WhatsApp broadcasts and bulk messaging: what is allowed and what gets you limited

WhatsApp allows messages to people who gave you their number and opted in to hear from you, and prohibits spamming or surprising people. Its Terms of Service name bulk messaging and auto-messaging among impermissible communications for consumer use, and its policy says systems may limit how many messages a business can send. Broadcast lists and the official API are the sanctioned routes for sending to many people, each with conditions.

"Can I send a WhatsApp message to my whole list?" gets three different answers depending on who is asking and which product they use. This post sets out what WhatsApp's own documents say, how broadcast lists and the official API differ, and a safer way to reach many people. The quotes below come from WhatsApp and Meta pages read on 25 October 2026. Rules change, so read the originals.

What do WhatsApp's documents actually say?

Two documents decide most of this.

The Business Messaging Policy (last updated 23 September 2026). Key lines:

• You may contact people on WhatsApp only if they have given you their mobile phone number or username, and have given opt-in permission to receive the messages.
• "Users should expect the messages and calls they receive."
• Do not "confuse, deceive, defraud, mislead, spam, or surprise people" with your communications.
• Businesses must provide clear instructions for how people can opt out of specific categories of messages, and must respect requests to block or discontinue.
• "Our systems may limit the amount of messages a business can send or calls a business can initiate."
• WhatsApp may limit or remove access to WhatsApp for Business, or limit your ability to send messages.

The Terms of Service (effective 4 January 2021). Under acceptable use they list "bulk messaging, auto-messaging, auto-dialing, and the like" among impermissible communications.

The policy does not use the word "broadcast". The practical reading is that the test is not how many people you message but whether each person expects it and wants it.

Broadcast lists, the official API and group chats

The saved number condition is worth noticing. It is WhatsApp's way of limiting broadcast lists to people who already know you. If you rely on it, you reach fewer people but the ones you reach have some relationship with you.

On the API, Meta's pricing page says it charges per delivered message, by category (marketing, utility, authentication) and recipient country, and that users must have opted in to receive messages. Our WhatsApp Business API cost post explains the cost side.

What counts as opt-in?

The policy says people must give you their number and permission. A defensible opt-in has four parts:

1. Specific. The person agreed to WhatsApp messages, not just "updates".
2. Recorded. You can show when and how they agreed, such as a form field with the date.
3. Honest about content. If you say "order updates", do not send offers.
4. Easy to leave. The first message says how to stop, and you honour it everywhere.

A business card or a LinkedIn connection is not the same as consent to marketing on WhatsApp. Under data protection law, a mobile number linked to a person is personal data. Under the GDPR an individual can object to direct marketing at any time (Article 21). Our double opt in glossary entry explains the stricter form. This is not legal advice.

What gets a sender limited?

WhatsApp does not publish its scoring, so none of this is a rule. From the policy and the way people use the app, the common causes are:

• Messages to people who did not expect them, who then block or report.
• Many new chats from an account with little history.
• The same text to many people.
• Messages after a stop request.

The policy gives WhatsApp room to act on any of these. It says it may limit your ability to send messages, remove access, or bar an organisation from future use. A limit is not a one time penalty you can wait out with certainty. Build on the assumption that quality decides your volume.

A safer way to send to a list

If you must reach many people, this sequence reduces risk. The example is made up.

Step 1. Clean the list. Keep only people who opted in or who wrote to you first. Remove everyone else, however good the offer.

Step 2. Segment. A message about a specific product to people who asked about it performs differently from a general offer to all.

Step 3. Send a small batch first. Ten or twenty people, read the answers yourself.

Step 4. Write each message as a conversation opener. For example, made up:

"Hi Dana, you asked us to let you know when the spring tour dates were set. They are now up. Want me to send the dates for the 12th?"

Step 5. Watch the first replies. If several people answer with annoyance, stop and fix the list.

Step 6. Space the rest. Send in waves over days, not in one burst, and stop messaging anyone who says stop.

Where does Sellinger fit?

Sellinger is not a broadcast tool. You connect your own WhatsApp account, and the agent answers people who write first and sends first messages and follow ups through that account. WhatsApp itself limits outbound messaging, so first messages run at a small daily volume. Before every WhatsApp send the platform checks the team's suppression list. When a contact replies with STOP or a similar opt out, the contact goes on that list and the agent stops. The daily limits and pacing guide explains the per account limits.

Sellinger's route is different from the official API, and that is a trade you should make knowingly. WhatsApp's rules apply to the account you connect. No tool can guarantee that WhatsApp will never limit a number.

Questions to ask before sending

• Did every person on this list give me their number and agree to WhatsApp messages?
• Can I show when and how?
• What does the first message say about who I am and how to stop?
• What will I do if five people complain in the first hour?
• Is WhatsApp the right channel, or is email or LinkedIn a better fit for this audience?

For cold audiences, the answer to the last question is usually that WhatsApp is the wrong first channel. Our post on WhatsApp cold outreach explains why, and the broader strategy post covers the permitted uses.
