How to send bulk WhatsApp messages without losing your number

If your customers live on WhatsApp, sooner or later you will want to send the same message to a lot of them at once: a festive offer, a price change, a batch of appointment reminders. There are four realistic ways to send bulk messages on WhatsApp, and each one trades reach, cost and risk differently. Choosing the wrong one is how businesses lose the number their customers know them by.

Here is each method honestly — what it can do, what it costs, where the limits are — and the habits that keep a number healthy whichever route you pick.

1. Broadcast lists in the WhatsApp Business app

The simplest bulk WhatsApp message is the one built into the app on your phone. A broadcast list is a saved list of contacts; you type one message and each person receives it as an ordinary one-to-one chat from you. Replies come back to you individually, not to the whole list.

WhatsApp’s Help Center sets out the rules:

• You can include up to 256 contacts in each broadcast list, and create as many lists as you like.
• Only people who have saved your number in their phone’s address book receive the broadcast. Everyone else on the list simply never gets it, and you are not told.
• Broadcast lists are not supported on WhatsApp Web, Windows or Mac — you send them from the phone.
• People in some countries may see a monthly broadcast limit, which WhatsApp says is rolling out gradually.

The saved-number rule is the real ceiling. A broadcast list works well for a small, loyal audience — regulars, a dealer network, a class of students — who already have you in their contacts. It does not work for a list of new enquiries or for a spreadsheet of past customers who never saved your number. For those, WhatsApp’s own help article points businesses towards marketing messages rather than broadcast lists.

2. The official WhatsApp Business Platform (Cloud API)

If you want WhatsApp Business API for bulk messaging, this is the route Meta built for it. You register a number on the WhatsApp Business Platform and send from software rather than a phone. Recipients do not need to have saved your number. In exchange, Meta sets conditions.

Opt-in comes first

Meta’s opt-in rules say a business may message someone on WhatsApp only if that person has given you their mobile number and has agreed to receive messages from your business. The opt-in must clearly say they are opting in and must name your business. It does not have to be collected on WhatsApp — a website form, an SMS, a phone call or a signed paper form are all listed as acceptable methods, as long as it complies with the law where you operate.

Bulk messages must use approved templates

Template messages are the only kind you can send to someone who has not messaged you recently — that is, outside the customer service window. Templates are reviewed by Meta when you create or edit them, and only a template with the status APPROVED can be sent. Our guide to WhatsApp marketing message templates covers how to write ones that pass review.

Meta bills per delivered message

Meta charges per delivered template message. The rate depends on the template’s category (marketing, utility or authentication) and on the recipient’s country calling code, and Meta revises its rates from time to time, so check Meta’s official pricing page rather than a figure quoted in a blog post. Ordinary replies you send inside an open customer service window are free today, but Meta has announced that from 1 October 2026 it will charge for these service messages too, with a free allowance of 1,000 a month per business phone number (what changes on 1 October).

Messaging limits grow with quality

Meta caps how many unique people you can reach with business-initiated messages in a moving 24-hour window. According to Meta’s messaging limits documentation:

• The limit is set for the whole business portfolio and shared by every number in it.
• A newly created portfolio starts at 250 unique recipients per 24 hours.
• It rises to 2,000 once you complete a scaling path — verifying your business, or delivering 2,000 messages to unique users within 30 days using templates with a high quality rating.
• After that it steps up automatically to 10,000, 100,000 and then unlimited, provided your messages stay high quality and you have used at least half of your current limit in the last seven days.

This is the most dependable way to send bulk WhatsApp messages at volume. Pingly lets you connect your own WhatsApp Cloud API account, so Meta bills you directly for messages while campaigns, templates and replies run in one shared inbox.

3. Your existing number, connected by QR

The third option is the one most people mean by a WhatsApp bulk message sender: software that links your existing WhatsApp or WhatsApp Business number the way WhatsApp Web does, by scanning a QR code, and then sends messages from it one by one. There is no template approval and no per-message fee from Meta. That is why it is popular — and why you need to understand the risk.

WhatsApp’s Terms of Service do not allow it for marketing. They prohibit using the service to send “bulk messaging, auto-messaging, auto-dialing, and the like”, and any non-personal use WhatsApp has not authorised. Sending bulk marketing from an account on the regular app is against those terms, and WhatsApp can restrict or ban a number that does it. Any tool that connects this way — Pingly included — can reduce how likely that is. None can remove it.

What Pingly does is pace sending so a number behaves like a busy person, not a machine. A number that connects today and sends hundreds of messages is the pattern most likely to be flagged, so Pingly enforces a warm-up counted from the day a number first connects. These are the daily caps at the default Balanced pacing level:

A Safe level lowers these caps to 60% and a Fast level raises them to 140%. Pacing can be switched off entirely; we would not recommend it. Alongside the caps, Pingly:

• Waits a random gap between messages — 10 to 35 seconds at the Balanced level — with an occasional longer break, so sends never arrive with machine regularity.
• Shows the “typing…” indicator for a few seconds before each message, as a person would.
• Varies the wording with spintax: write {Hi|Hello|Good morning} and each recipient gets one of the options, so a campaign is not hundreds of identical messages.
• Pauses the number automatically. A send error that looks like a restriction pauses bulk sending for two hours; if most recent messages stop being delivered, the campaign is halted and the number rests for twelve hours.
• Skips every contact marked as opted out.

The reasoning is on our WhatsApp broadcast page. The honest summary: a QR-connected number suits small, warm lists and testing whether campaigns work for you at all. Once volume matters, or the number is one you cannot afford to lose, move marketing to the official API.

4. How to send bulk messages on WhatsApp from Excel

Most businesses already have their customers in a spreadsheet — an export from billing software, a CRM or a form. A spreadsheet is not a sending channel; it feeds one of the methods above. In Pingly the steps are:

1. Prepare the sheet. Only a phone column is required. Name, email and tags are optional; put several tags in one cell, separated by commas. Any other column — say product_name or due_date — is saved against the contact so it can fill a variable later. The import screen has a sample CSV to start from.
2. Import it. Go to Contacts and choose Import CSV. Upload a .csv or .xlsx file, pick a country code if your numbers are written without one, and optionally put everyone into a new or existing group.
3. Check the result. Invalid numbers are skipped, repeated numbers are merged, and existing contacts are updated rather than duplicated. A summary shows the counts.
4. Build the campaign. Under Campaigns, choose New Campaign and work through the five steps — Name, Template, Recipients, Variables, Schedule. Pick recipients by group or tag, map {{name}} and your other variables to the columns you imported, then send now or schedule it.

For a one-off send you can also upload the file straight into the Recipients step (.xlsx, .xls or .csv, up to 10,000 rows) and pick the phone and name columns there. Either way, the rules of the channel you chose still apply: a list of people who never agreed to hear from you is still that, whatever format it arrives in.

Bulk WhatsApp methods compared

How to avoid getting your number restricted

Whether your WhatsApp bulk messages go through the API or a QR-connected number, WhatsApp judges you mainly by how recipients react. Its Business Messaging Policy says people can block or report businesses, and that WhatsApp limits how many messages a business can send when its quality stays low. These habits are what keep quality up — and they are the practical answer to how to send bulk messages on WhatsApp without getting banned:

• Get opt-in and keep a record of it. Note where and when each person agreed — a checkout box, a form, a signed register. It is Meta’s rule for the API and your best defence anywhere.
• Send only what people signed up for. Someone who asked for delivery updates did not ask for your festive sale. Relevance is what stops the block button.
• Put an opt-out line in every marketing message, such as “Reply STOP to stop these messages”, and honour it — WhatsApp’s policy requires you to respect opt-out requests. Pingly skips opted-out contacts in every campaign. On API numbers a STOP reply marks the contact automatically; on a QR-connected number, mark them opted out yourself.
• Start small. Send the first campaign to your most engaged customers, watch replies and blocks for a day, then widen it.
• Never buy lists or scrape numbers from groups. Strangers are the people most likely to report you.
• Personalise and vary. Use the customer’s name, keep messages short, and avoid sending a bare link with no context.
• Send at sensible hours and reply to replies. Two-way conversation is what a healthy business number looks like.

Frequently asked questions

Can I send bulk WhatsApp messages without adding the contact?

Not with a broadcast list — WhatsApp only delivers broadcasts to people who have saved your number. The official Business Platform does not need recipients to save your number, provided they have opted in. A QR-connected tool can technically message unsaved numbers, but messages from an unknown number to people who do not recognise you are the ones most likely to be reported.

How many WhatsApp messages can I send per day?

A broadcast list holds up to 256 contacts. On the official platform a new portfolio can reach 250 unique people in 24 hours, rising with quality. WhatsApp publishes no figure for regular accounts; Pingly’s caps for a QR-connected number rise from zero to 1,000 a day over 60 days.

Is sending bulk WhatsApp messages allowed?

On the WhatsApp Business Platform, with opt-in and approved templates, yes — that is what it is for. From a regular WhatsApp or WhatsApp Business app account, WhatsApp’s terms prohibit bulk and automated messaging. Separately, Meta expects businesses to follow the marketing and privacy laws that apply to them, so check your local rules if you are unsure.

Is there a free way to send bulk WhatsApp messages?

Broadcast lists in the Business app are free, within the limits above. On the API, Meta charges per delivered template message; replies inside an open customer service window are free until Meta’s announced change on 1 October 2026, after which only the first 1,000 a month per number are. Pingly has a 14-day free trial with no credit card; after that, Starter is ₹999/month + GST for 5,000 messages a month, 2 QR-connected numbers and 10 campaigns. Pro is ₹2,999/month + GST (50,000 messages, 6 numbers, 50 campaigns) and Business is ₹7,999/month + GST (5,00,000 messages, 10 numbers, unlimited campaigns). See pricing for the details.

Can I send bulk messages from WhatsApp Web?

Not with broadcast lists — WhatsApp says they are not supported on Web, Windows or Mac. From a computer, it means the official platform or a tool connected to your number.

What should I look for in a WhatsApp bulk message sender?

Support for the official API as well as QR sending, so you can move up as volume grows; opt-out handling that actually stops sends; pacing that is written down; and delivery and read reports per contact. Be wary of any tool promising unlimited sending from a new number. If you want to try the approach described here, start a free trial with one number and a small, opted-in list.
