WhatsApp Rate Limiting
Sending unique message recipients per day according to tiers.
WhatsApp has imposed rate-limiting when ramping up your Official WhatsApp messaging application.
There are three WhatsApp's rate limit tiers:
Your Official WhatsApp phone number will be automatically moved to the next tier by WhatsApp if it meets the following requirements:
- Total number of unique recipients across the past 7 days
- Message quality rating
Suppose within the past 7 days, the Official WhatsApp phone number has communicated with 2x the unique recipients of the Tier's per-day limit and maintains a good "quality rating" from WhatsApp. The Official phone number will move to the next tier on the next day automatically.
Since WhatsApp encrypts messages, it relies on user feedback to measure the quality of messages. WhatsApp uses it to track "quality rating" for senders, which can affect how users are able to move between rate limiting tiers.
To maintain high quality, it recommends the following:
- Highly personalised and useful messages to users.
- Avoid sending customers too many messages a day.
A low-quality rating can result in an Official WhatsApp phone number preventing from moving to a higher rate tier or, in some cases, to a lower rate limit tier.
