Broadcast Messages on WhatsApp Business
Using the WhatsApp Business API, businesses can send broadcast messages to all contacts who have previously opted in. This is the crucial difference to the standard WhatsApp app: The API allows scalable sending to thousands of recipients simultaneously, including personalized content from the CRM. Use cases for broadcast messages: Product news and offers: Announcements directly to the target group. Campaigns and promotions: Seasonal promotions with high conversion rates. Transactional messages: Order confirmations, shipping information, appointment reminders. Re-engagement: Reactivate inactive customers with relevant content. Segmentation for targeted broadcasts: With hellomateo, contact lists can be segmented according to various criteria – e.g., purchasing behavior, location, or last interaction. This way, each segment receives a tailored broadcast message, significantly increasing relevance and conversion. GDPR-compliant broadcast sending. In Germany and the EU, broadcast messages may only be sent to recipients with explicit opt-in. hellomateo helps companies collect and manage consent in a legally compliant manner – for GDPR-compliant WhatsApp marketing without legal risks.
