There are different messaging limits tiers that are enforced by WhatsApp to ensure that businesses don’t send too many spam and promotional messages and make sure that WhatsApp users always have a good user experience.  Therefore, the limits on messages are imposed based on your quality rating which is calculated based on how users received your messages in the past seven days. If you make sure to comply with WhatsApp commerce policy and maintain a high-quality rating you move up the messaging tiers and send more messages per day. Here are the messaging tiers as specified by WhatsApp and Meta: • Level 1: 1,000 business-initiated conversations (with 1,000 unique customers) in a rolling 24-hour period. • Level 2: 10,000 business-initiated conversations (with 10,000 unique customers) in a rolling 24-hour period. • Level 3: 100,000 business-initiated conversations (with 100,000 unique customers) in a rolling 24-hour period. • Level 4: unlimited business-initiated conversations in a rolling 24-hour period.
