The quality-based rate limits do NOT limit the number of messages your business can send, just the number of customers you are trying to message. It also does NOT apply to messages sent in response toa user- initiated message within a 24-hour period.
Allows your business to send messages to 1K unique customers in a rolling 24-hour period. Tier 2: Allows your business to send messages to 10K unique customers in a rolling 24-hour period. Tier 3: Allows your business to send messages to 100K unique customers in a rolling 24-hour period. Note: A business starts in Tier 1 when it registers its phone number.
