WhatsApp broadcast & bulk messaging
Send the right message to the right list - every time.
Send bulk WhatsApp messages the official way. Pick an approved template, choose customers by tag or upload a list, schedule it, and watch sent, delivered, read and failed update live - with opt-outs handled for you.
Bulk WhatsApp campaigns, on the official API.
Target by tag
Send only to the contacts you tagged - '#vip', '#diwali-2025', '#trial' - or upload a CSV list of numbers.
Opt-in respected
Choose opted-in contacts only. Replies like STOP or UNSUBSCRIBE opt the customer out automatically.
Schedule ahead
Pick a date and time, and the campaign goes out on its own.
No duplicate sends
Numbers are de-duplicated before sending, so nobody gets the same message twice.
Rich templates
Image, video or document headers, variables, and URL, call or quick-reply buttons.
Clear failure reasons
Every failed recipient shows why - token expired, not on WhatsApp, template not approved - so you can fix it and send again.

A list you upload can hold up to 5,000 numbers per campaign. Your daily reach is also set by Meta's messaging limit for your number, which rises as you keep sending messages people want.
WhatsApp requires a template for any message you start, or send after the 24-hour customer-care window. Once Meta approves it, you can use it in broadcasts.
Broadcast lists in the WhatsApp Business app reach only people who saved your number, up to 256 per list. The API sends approved templates to opted-in customers at scale, with delivery reports.
Meta charges per delivered template, by category and by the recipient's country. See the live rates on the pricing page.
