send messages in batches, not all at once. When you start using the bot, send no more than 6 -12 messages per minute, i.e.Before connecting to a completely new number, you can use WhatsApp personally for some time (chat with other numbers so that you have a variety of incoming and outgoing messages from different numbers).
To do this, add reply buttons (e.g., “Write 0 to unsubscribe”) You can receive messages from clients using a webhook.
