Messaging limit
Updated
Quick answer: The messaging limit is the maximum number of unique customers a business can send template messages to in a rolling 24-hour period on the WhatsApp Business API. New businesses start with a low limit, which Meta raises step by step as you complete Business Verification, send to more customers and keep a good quality rating. Replies to customers who message you first do not count towards it.
How many customers you can start conversations with in 24 hours.
If you send low-quality messages that get blocked or reported, Meta can stop raising your limit or lower it. Check your current limit in WhatsApp Manager.
