Limitations

Messaging Limits:

Messaging limits determine the maximum number of business-initiated conversations you can initiate using each of your phone numbers in a rolling 24-hour period. A business-initiated conversation begins when the first template message is delivered to a customer and ends 24 hours later.

Business phone numbers with a connected status and approved display name can initiate conversations with the following number of unique customers in a rolling 24-hour period;

• 1K unique customers

• 10K unique customers

• 100K unique customers

• An unlimited number of unique customers

This amount starts at 1K unique customers and scales automatically based on phone number status, phone number quality rating, and how often you initiate conversations with unique customers.

If you meet these requirements but your business phone number has a low quality rating, you may continue to be limited to 250 business-limited conversations until its quality rating improves.

Checking Limit

You can check your current messaging limits in the ‘WhatsApp Manager -> Overview Dashboard -> Insights tab’.

The panel depicted below will only show your current limit if your messaging limit has increased from the default limit of 250.

Increasing your limit

Each time you initiate a new conversation with a unique customer we will determine if your limit should be increased. This determination is based on the following criteria;

• Your phone number status is connected

• Your phone number quality rating is Medium or High

• In the last 7 days you have initiated X or more conversations with unique customers, where X is your current messaging limit divided by 2

If you meet all conditions, Meta will increase your messaging limit by one level in 24 hours.

Examples

Messaging limit increased from 1K to 10K in 2 days;

	Day 1	Day 2	Day 3	Day 4	Day 5
Business-initiated conversations (new)	500	500
Business-initiated conversations in last 7 days	500*	1,000
Messaging limit	1K	10K

If the 500th conversation is initiated at 3:00 PM for example, the messaging limit is increased at 3:00 PM the following day (i.e 24 hours later)

Messaging limit increased from 1K to 10K in 4 days;

	Day 1	Day 2	Day 3	Day 4	Day 5
Business-initiated conversations (new)	100	200	200	300
Business-initiated conversations in last 7 days	100	300	500*	800
Messaging limit	1K	1K	1K	10K

If the 500th conversation is initiated at 7:00 PM (for example), the messaging limit is increased at 7:00 PM the following day (i.e. 24 hours later)

Decreasing your limit

Each time you initiate a new conversation with a unique customer Meta will check your phone number quality rating. If the rating has been found to be marked spam/blocked for the last 7 days, Meta will immediately decrease your messaging limit by one level.

Quality Rating

Your quality rating is based on how messages have been received by recipients over the past seven days and is weighted by recency. It is determined by a combination of quality signals from conversations between businesses and users. Examples include user feedback signals like blocks, reports and the reasons users provide when they block a business.

Your business phone number's status, quality rating, and messaging limits are displayed in the WhatsApp Manager -> Account tools -> Phone numbers tab in WhatsApp Manager

it is normal for numbers with high traffic to experience quality changes within short intervals (even within minutes).

Maintaining High Quality

• Make sure messages follow the WhatsApp Business Policy and Commerce Policy

• Only send messages to users who have opted into receiving messages from your business

• Make the messages highly personalised and useful to users. Avoid sending open-ended welcome or introductory messages

• Be mindful of messaging frequency; avoid sending customers too many messages a day. Be thoughtful of informational messages, optimising for content and length
