How to Send a Bulk WhatsApp Message to Many People in ChatSyncs

​

Before you start

• A WhatsApp Business Account connected to ChatSyncs, with an active phone number.
• A subscriber list already in ChatSyncs — import one first if you haven’t, via How Do I Import Subscribers Using a CSV File?, How Do I Import Subscribers from Google Sheets?, or How Do I Add a Subscriber Manually?.
• An approved Message Template, if you’re sending an Anytime broadcast (the type most people use). Meta has to approve a template before it can be used, and that can take anywhere from a few minutes to a full day. Example: you want to send a “Diwali Sale” message to 1,000 customers today, but your template still shows Pending — the broadcast can’t go out until Meta approves it, so it’s faster to get the template approved before you sit down to build the campaign, not while you’re building it.
• Read WhatsApp Rules: How to Never Get Banned first — a broadcast is exactly the kind of send that can hurt your quality rating if the audience didn’t opt in or isn’t engaged. See What WhatsApp API Pricing Really Means too, since every broadcast recipient outside their Customer Service Window is a paid template send.

​

Create a broadcast campaign

​

Configure the campaign

1

Campaign Name

An internal name to identify the campaign, e.g. Summer Promotion Campaign or season_sale.

2

Broadcast Type

24 Hours sends only to subscribers currently inside the WhatsApp 24-hour customer service window — regular messages, no template approval required. Anytime sends to all selected subscribers regardless of window, but because some of them are outside it, only an approved WhatsApp template can be used. See the 24-hour customer service window.

3

Select Template (Anytime only)

Pick an approved template from Select Template. This step only appears for Anytime — inside a 24 Hours broadcast you’re free to send any message type (text, service/session messages, etc.), so no template is required. Don’t have one yet? Click Create right next to the dropdown, or create a WhatsApp message template first — either way, you need an approved template before you can send an Anytime broadcast.

If the template you pick has variables — placeholder text, or a header image/video/document — ChatSyncs asks for those values right below the dropdown:

4

Include or exclude labels

Include Label IDs sends only to subscribers with that label (e.g. Customers, Leads, VIP Customers). Exclude Label IDs skips subscribers with that label (e.g. Unsubscribed, Do Not Disturb). Don’t have a label yet? Create a label in Subscriber Manager.

5

Country of the Subscriber (optional)

Only send to subscribers in a specific country, e.g. India.

6

Use Recently Added Subscribers (optional)

Enable this to target only recently added subscribers — useful for welcome campaigns, onboarding sequences, or new-lead engagement.

7

Assign Label After Broadcast (optional)

Auto-assign a label to every subscriber once the broadcast sends successfully — useful for segmenting an audience, filtering future broadcasts, triggering automations, and tracking campaign performance.Example: a Summer Sale broadcast with Assigned Label set to Summer_Sale tags every recipient — Rahul, Priya, Amit, and everyone else — with Summer_Sale the moment they receive it, so you can target exactly that audience again later (e.g. a follow-up discount reminder only to people who already saw the sale).

8

Sending time (optional)

By default the campaign sends as soon as you finish building and save it. Toggle Send later on to pick a future date and time instead — useful for holiday campaigns, product launches, or timing the send to your audience’s business hours.

​

Filter by Custom Field

• Custom Field is the category — like asking “which box am I checking?” e.g. Name, City, Plan Type.
• Custom Field Contains Value is the answer you’re looking for inside that box — e.g. if the field is Name, the value could be Rahul. If the field is City, the value could be Bangalore.

Monitor campaign statistics

​

Campaign actions

• View Report — detailed broadcast statistics and recipient information.
• Download Report — exports the report as a CSV for analysis and record keeping.
• Resend Failed Messages — retries delivery for messages that failed, e.g. after correcting invalid phone numbers.
• Delete Campaign — removes the campaign from the list.

​

Tips for successful broadcasts

• Start small on your first send. Target 100–200 subscribers first rather than your whole list, then check your quality rating a few hours later before scaling up to the rest.
• Don’t broadcast to cold lists. Contacts who never opted in or haven’t interacted with your business are far more likely to block or report you — that damages your quality rating and can shrink your daily messaging limit.
• Time it to your audience, not yours. Send during business hours in the recipient’s timezone — messages that land at odd hours get more blocks.
• Monitor results after every send. Check Processed / Delivered / Opened / Unreached on the campaign row. If blocks or Unreached are unusually high, pause and review your targeting before sending the next one.
• Know your daily limit before you send. Your WhatsApp Business Account’s daily conversation limit caps how many subscribers can actually be reached — see Understanding WhatsApp Quality Rating for how quality rating affects that limit over time.
