Can I use the Chat API to send WhatsApp bulk messages?
The Chat API allows you to process an unlimited number of messages. At the same time, you should not send more than 6000 messages per day, this is about 5-10 messages per minute, unless, you are not interested in blocking your number with WhatsApp anti-spam algorithms.
Facebook's policy does not approve of any automation of working with the messenger. This should be taken into account and build your work with WhatsApp according to the following principles:
1-Involve the client in the dialogue. If the client writes to you first or is interested in your messages, then this is an indicator of "Good" communication and WhatsApp will not have any complaints about you. Use interesting content, widgets, construct links to the dialog and make them publicly available so that customers write to you first.
2-It is important to maintain an approximate equal ratio of the number of incoming and outgoing messages. If only outgoing messages prevail, this may arouse suspicion among the WhatsApp algorithms.
3-Fill out your WhatsApp profile or install the WhatsApp business App to form a greater understanding and interest in the client about you and your business.
4-Add the contacts to whom you send messages to your contact list in WhatsApp.This can significantly reduce the likelihood of a ban.
5-It is important to understand that at the beginning of communication with a new number, the user has the opportunity to mark your message as spam. It is enough from 5 to 10 such clicks and your number will be blocked. Therefore, it is worth paying special attention to the welcome message.
6-Send different messages each time, if possible, use fewer links, as they arouse suspicion in the Anti-spam system WhatsApp. It's a good idea to use link shorteners.
