How do I send bulk WhatsApp messages to customers?

Put the number on the WhatsApp Business API, get a marketing or utility template approved, build an audience of people who opted in, and send within the messaging limit — stopping the sequence for anyone who replies.

Put the number on the WhatsApp Business API, get a marketing or utility template approved, build an audience of people who opted in, and send within the number's messaging limit. A campaign tool schedules the send, holds the rest when the limit is reached, and stops the sequence for anyone who replies.
