WhatsApp broadcast
A WhatsApp broadcast is the mass sending of the same message to many recipients, delivered to each one as an individual chat rather than a group. On the WhatsApp Business app it is limited to lists of recipients who have saved the number in their address book; through the Business API it is done with approved templates, without that constraint and at much higher volumes, within the business portfolio's messaging limits.
Via the API, a broadcast is a campaign: you select a segment of opted-in contacts, choose a template (usually marketing) and the platform performs the sends, personalizing the variables for each recipient. The message appears to the customer as a normal one-to-one chat, and replies open individual conversations that agents or automations can handle. Delivery is tracked with per-message statuses: sent, delivered, read.
The app's limits are well known: broadcast lists capped at 256 contacts and delivery only to people who have saved your number, which makes it unsuitable for real campaigns. On the API, the constraint is Meta's messaging limits, calculated per business portfolio: you start at 250 unique recipients in 24 hours and move up to 2,000, 10,000, 100,000 and then no fixed limit, with quality and volume. Cold lists and excessive frequency degrade the quality rating and, with it, sending capacity.
Broadcast campaigns are the heart of SendApp: tag-based segments, templates personalized with variables, scheduled sends and delivery reports, on SendApp Agent as on the other connected channels.
