Broadcast lists are one of the most useful free tools a political organization or social movement has on WhatsApp. They are one of the 6 best WhatsApp strategies for political campaigns we have looked at.
A broadcast list sends one message to many people, but each person gets it as a normal private chat. This guide covers how to get the most out of them for a campaign.
What broadcast lists are
A broadcast list lets you send one message to many contacts at once, and each person receives it as a normal one-to-one chat rather than a group message. For a campaign, that means you can reach a lot of people while the message still reads as personal.
Why they work for campaigns
- They feel personal: a one-to-one message tends to get read, where a busy group chat gets muted.
- The message lands directly: it arrives in a private chat instead of getting lost in a group.
- You can segment: separate lists by interest or area let you send the right message to the right people.
Training activists
Show your activists how to build good lists. A simple start is to sort their contacts into at least two:
- Committed supporters: people you know will read and back you.
- Maybe interested: people who might care but do not always follow your topics.
Run a session on how to adjust the message for each group, so it reads as personal and not as spam.
Share content through an internal group
Set up an internal WhatsApp group where activists get the content to forward to their own lists. It also gives them a place to compare notes on what to change for each audience.
Tip: ask activists to reword the text for their own audience. A message that speaks to someone’s concerns lands better than a forwarded copy.
Writing the message
- Keep it clear: short and to the point. Use bold or italics for the parts that matter.
- Ask for something: point people to a specific action, like coming to an event, signing a petition, or inviting a friend.
- Let activists make it theirs: a message in their own voice fits their contacts better than a script.
Build relationships, not blasts
The point of a broadcast list is a real connection with each person, not an impersonal blast. A few things help:
- Send from someone they trust: people read and act on messages from a person they know.
- Stay in touch: regular, relevant updates build familiarity over time.
- Listen back: invite replies and use what people tell you to make the next message more relevant.
Making sure messages get delivered
Broadcast lists have one rule that trips people up: a message only reaches someone who has your number saved in their phone. If they have not saved you, they get nothing. This is the single biggest thing to get right.
Why saved contacts matter
If someone has not saved your number, your broadcasts will not reach them. You can check in your private chat with them: a single tick means the message was sent but not delivered, which usually means they have not saved you.
Getting people to save your number
- Just ask them to save it: tell people directly to add your number. A click-to-chat link with a ready-made message is an easy way to start the chat, then ask them to save you.
- Give them a reason: when activists first write, they can ask people to save the number to keep getting updates, and say what those updates are, alerts, early news.
Limits and timing
Each broadcast list holds up to 256 contacts. Split them into focused lists by interest or area so each message fits its audience.
- Wait a minute between broadcasts: if you are sending to several lists, leave at least a minute between them to avoid delivery failures.
- Keep the pace steady: about one list per minute is a safe rate.
What changed in 2025 (and what didn’t)
In 2025 WhatsApp trimmed broadcasting on the free WhatsApp Business app: the app’s dedicated marketing broadcast feature was pulled, and Meta began steering large-scale, promotional outreach toward the paid official Business API, Channels and Communities. It’s worth knowing what this did and didn’t touch before you build a campaign on top of it.
- The classic broadcast list still works. You can still create a list of up to 256 saved contacts and send them a message that lands as a private, one-to-one chat, exactly the personal-feeling tool this article is about. That capability was not removed.
- Treat it as personal outreach, not bulk marketing. The direction of travel is clear: Meta wants promotional blasting to happen through opted-in, paid channels. Keep your broadcasts genuinely personal and relevant, and you stay on the right side of that line.
- Plan an upgrade path. When you outgrow 256 contacts per list, the compliant next steps are a Community announcement group (up to ~5,000 members, notifications on by default, numbers hidden) or the official Business API, not a bulk-sender app bolted onto a personal number.
Sending bulk broadcasts through the WhatsApp Business API
When broadcast lists aren’t enough, say you need to reach people who haven’t saved your number, or message a very large opted-in list, the next step up is the official WhatsApp Business API, offered by providers such as Wati.
Using an official API provider
A provider like Wati connects through the official WhatsApp Business API, which lifts most of the limits on a personal number:
- Approved templates: pre-cleared templates for utility, authentication, service and marketing messages.
- CRM and automation: connect a CRM and automate replies with chatbots.
- Shared team inbox: several people can reply from one verified number, which suits campaign and support teams.
If you can’t access the official API
The official API isn’t open to everyone, political and electoral use is frequently restricted, and providers may decline those applications. If that’s your situation, you can still automate around compliant methods with a workflow tool like n8n (which you can even self-host) alongside other non-official API options. The golden rule: don’t bulk-blast from a personal number with a “sender” app, that’s the fastest way to get blocked. See our automation guide for what’s available if the API isn’t an option.
Common pitfalls
Two things go wrong most often: lists go stale, and people tune out from too many messages. To handle them:
- Keep lists current: update and re-sort them as people’s interest changes.
- Don’t overdo it: too many messages and people switch off. Space out announcements and keep them worth reading.
Used well, broadcast lists are one of the strongest free tools a campaign has. When you need announcement-style reach beyond 256 saved contacts (with notifications on by default and phone numbers hidden) pair them with the empty-community “channel” hack, and see where they fit among the 6 best WhatsApp strategies for political campaigns.
Frequently asked questions
How do I create a Broadcast List in WhatsApp?
Open WhatsApp and tap the three dots in the top right corner. Select “New Broadcast,” then choose up to 256 contacts from your list. This lets you message many contacts simultaneously without sacrificing a personal touch.
Will a contact be notified when they are added to a Broadcast List?
No, contacts do not receive any notification when they are added to a Broadcast List. This ensures privacy and avoids unnecessary notifications for your contacts.
Do contacts need to have my number saved to receive my messages?
Yes. For a contact to receive messages sent via a Broadcast List, they must have your phone number saved in their contact list. This is the single most important factor for successful delivery.
How can I reach contacts who haven’t saved my number?
Standard broadcast lists can’t do this, but the official WhatsApp Business API can. A provider like Wati lets you message opted-in contacts using approved templates, broadening your reach well beyond people who already have you saved.
Did WhatsApp remove broadcast lists in 2025?
No. In 2025 WhatsApp removed the dedicated marketing-broadcast feature from the free Business app and pushed promotional sending toward the paid Business API, Channels and Communities. The classic broadcast list, up to 256 saved contacts, delivered as individual private chats, still works for personal, non-marketing outreach, which is exactly how a campaign should use it.
