Why unofficial bulk senders lose numbers
Search for bulk WhatsApp messages in Arabic and many results offer to send «without a ban». They are usually browser extensions, WhatsApp Web scripts or sender apps that push messages through an ordinary WhatsApp or Business app account. That breaks WhatsApp's terms, and numbers used that way are the ones that get banned.
No tool can make that safe, whatever the advert says. The route WhatsApp supports is the Business API: messages sent from your own business, using templates Meta has approved, to people who agreed to hear from you, within Meta's limits.
Even on the API, nobody can promise a number will never be restricted. Quality depends on how people react, and blocks and reports count against you. What the official route gives you is a published rulebook, a quality rating you can watch, and a documented way to reach more people as you earn it.
