The maximum number of messages that a business can initiate and send to customers within a 24-hour period is 250 conversations per WhatsApp number.
For example, if you have a large customer base (such as 10,000 contacts) and want to send a message to all of them, you will only be able to send the message to 250 contacts on the first day. On the following day, you can send it to another 250 contacts, and so on.
However, relying on random sending in this way may result in some contacts receiving the same message more than once, while other contacts may not receive the message at all.
{info} For verified accounts, you can increase the messaging limit by following the steps outlined in the Messaging Limits Document.
For new, unverified accounts, this document will show you how to divide your contacts into groups of 250 unique contacts, then assign a separate number to each group. This approach allows you to send messages (templates) to all your contacts in an organized manner, without duplication or randomness.
You can find detailed steps for this method in the Contact Grouping document.
