Broadcast in Business App vs Business API
The Business App has broadcast lists: you can send the same message to a maximum of 256 contacts per list. Critical limit: the recipient receives the message only if they have saved you in their contacts.
The Business API has no limit on the number of broadcast recipients. You can send approved templates to thousands of contacts simultaneously.
How to send a broadcast with Chat API
To send a broadcast with Chat API, use the bulk endpoint that allows specifying the recipient list, template to use, and personalized parameters for each recipient.
Broadcast personalization is fundamental for effectiveness.
Segmentation for effective broadcasts
Segmentation is the key to high-ROI broadcasts: send summer offers only to customers in warm geographic areas, send B2B product updates only to decision makers.
Measuring broadcast effectiveness
KPIs to monitor for WhatsApp broadcasts: delivery rate, read rate, response rate, and conversion rate.
Compare WhatsApp broadcast results with email marketing: WhatsApp reading rates are typically 3-5x higher than email.
