How to Prepare Your Team Before a WhatsApp Broadcast

Before you send a broadcast, settle five things with your team: who is on the list and why, who answers which kind of reply, what the replies will say, what the rules are, and what happens in the first hour. A broadcast is one message from you, but it turns into many separate conversations, so the preparation belongs to the whole team and not just whoever presses send.

Some of what follows comes straight from WhatsApp's documentation, and that's labelled with its source. Other points are suggestions for running a team, and those are marked as such.

Why the Team Needs Preparing

WhatsApp's help page on broadcast lists says that when someone replies to a broadcast, "their reply will also appear as a normal message and won't be sent to other contacts in the broadcast list." In other words, every recipient who answers starts a private conversation with your business. One broadcast to a few hundred people can become a few hundred chats at once.

The rules matter at team level too. WhatsApp's Business Platform documentation says it "might also limit or offboard your business from WhatsApp if your account receives excessive negative feedback from users." Its restrictions can be temporary, from 1 to 30 days on certain message types, or can escalate to account locks and, eventually, permanent disabling from the platform. A single team member who ignores a stop request or sends an off-brief message can affect the whole number.

Step 1: Confirm Who Is on the List, and Why

Start with the list, because it's the foundation for everything else.

WhatsApp's Business Messaging Policy states that "you may only contact people on WhatsApp if: (a) they have given you their mobile phone number; and (b) you have received opt-in permission." Its opt-in guidance adds that businesses "must clearly state that a person is opting in to receive communication from the business," must "clearly state the business's name," and "must comply with applicable law." The policy leaves the method of opt-in to the business, and the documented methods include SMS, a website, phone systems and in-person or paper forms.

For WhatsApp's own broadcast lists, there are two further facts. WhatsApp's help page says that "only people who've added you to their phone's contacts will receive your broadcast message," and that you can include "up to 256 contacts in each broadcast list."

Before the broadcast, the team should be able to answer two questions about any name on the list: how did this person opt in, and where is the record? If nobody can answer, that contact shouldn't be on the list yet.

Step 2: Assign Roles

This step is a suggestion for running a team, not a WhatsApp rule.

A broadcast produces different kinds of replies, and they need different people. A simple split is one person for buyers who are ready to order, one for questions before buying, one for problems with existing orders, and one person who owns every stop request, so none slips through. For a small business, one person can wear several hats, but each type of reply should still have a named owner.

Check also how your team will actually answer. WhatsApp's blog says one WhatsApp account can be used on up to five phones in total, one primary and four linked, and that for businesses, "additional employees are now able to respond to customers directly from their phones under the same WhatsApp Business account." That post doesn't have a date I could confirm, so check WhatsApp's current help pages for the exact limits that apply to your setup.

Step 3: Brief the Team on the Rules

Take ten minutes to go through the rules together, because the people sending replies are the ones who can break them.

The Business Messaging Policy says businesses "must respect all requests (either on or off WhatsApp) by a person to block, discontinue, or otherwise opt out," and that businesses should "provide clear instructions for how people can opt out of receiving specific categories of messages." It also sets out a broad principle: "Do not confuse, deceive, defraud, mislead, spam, or surprise people with your communications."

For the team, that translates into three plain rules. A stop request is honoured immediately, and the person is removed from every list. Nobody sends a follow-up pitch to someone who has said no. And nobody messages people who aren't on the approved list.

Step 4: Prepare the Replies

Prepared replies keep answers fast and consistent. WhatsApp's own description of the Business app lists features for this: "quick replies to easily answer the most common customer questions," "automated greeting and away messages," and "labels and lists to organize your chats and contacts for easy follow-up and management."

Write the quick replies before the broadcast goes out. The most useful ones usually cover price, delivery, payment, stock and the stop request. Then use labels to sort replies as they arrive, for example by whether someone is ready to buy, has a question or has a problem.

Away messages are worth setting too. WhatsApp's help page says you can choose to send them "at all times," on a "custom schedule" or "outside of business hours," and to choose who receives them, from everyone to only selected contacts. That way, if replies come in when nobody is free, the customer hears from you straight away instead of waiting in silence.

Personalise the prepared text before you send it. A reply that reads as though it was written for the person is more useful than one obviously pasted in.

Step 5: Know the 24-Hour Window and the Limits

This step matters if your team sends through the WhatsApp Business Platform, the API version, rather than the regular app. If you're not sure which you use, ask whoever set up your sending tool.

On that platform, Meta's documentation says that "when a WhatsApp user messages you or calls you, a 24-hour timer called a customer service window starts." Inside that window, you can send free-form service messages, and "when the window closes, you can only send pre-approved template messages." This is why replies to a broadcast need prompt attention. Once the window closes, the team can't simply type a normal message back.

There are also limits on how many people you can contact. Meta defines messaging limits as "the maximum number of unique WhatsApp user phone numbers your business can deliver messages to, outside of a customer service window, within a moving 24-hour period." Newly created business portfolios start at 250, and the limit can rise to 2,000, 10,000, 100,000 or unlimited. Meta lists high-quality messages as one of the criteria for automatic increases.

Tell the team what your current limit is, so nobody plans a send that can't go out.

Step 6: Test Before the Real Send

This step is a suggestion.

Send the broadcast to a small internal group first, such as a few team members' own numbers. Check that the message reads correctly on a phone, that links work, that the name and details are right, and that replies land with the person who's supposed to answer. Then walk through a stop request together, from the reply to the removal from the list, so everyone has done it once before it matters.

Step 7: Plan the First Hour

This step is a suggestion, and the time targets are internal goals, not WhatsApp requirements.

The first replies usually arrive soon after sending, so decide in advance who is online and for how long. A sensible order is to deal with stop requests first, because they're quick, then buyers who are ready to order, then problems with existing orders, then questions before buying, and general chat last. Agree internal targets for how fast each type gets an answer, write them down, and make sure the team can actually meet them. Don't send the broadcast at a time when nobody can answer.

After the Broadcast: Review Together

Once the first wave has been handled, take ten minutes as a team to look at what happened. How many replies came in, which questions came up most, which stop requests arrived and how quickly they were handled? WhatsApp's introduction to the Business app mentions messaging statistics, described as simple metrics "like the number of messages read." Your sending tool may show more or less than that. Use what's available and write down what you'd change before the next send.

FAQ

Who is allowed to receive my WhatsApp broadcast?

According to WhatsApp's Business Messaging Policy, you may only contact people who have given you their phone number and given you opt-in permission. WhatsApp's broadcast list help page adds that only people who have saved your number in their contacts will receive a list broadcast.

What happens to replies from a broadcast?

WhatsApp's help page says a reply appears as a normal message and isn't sent to the other contacts in the list, so each reply becomes its own conversation with your business.

What is the 24-hour customer service window?

On the WhatsApp Business Platform, it's a 24-hour timer that starts when a user messages or calls you. Within it you can send free-form service messages, and once it closes you can only send pre-approved template messages.

What happens if people block or report my broadcasts?

Meta's Business Platform documentation says it might limit or offboard a business that receives excessive negative feedback from users. Its enforcement includes restrictions of 1 to 30 days and account locks, and repeated violations can lead to permanent disabling from the platform.
