A funnel, not a megaphone
The quickest way to waste WhatsApp is to treat it like SMS: buy a list, blast an offer, count the blocks. It works better as a funnel people enter themselves. They tap an ad or a link, ask a question, get a useful answer, and hear from you again when you have something relevant.
In Kuwait a lot of buying already starts in a chat. Someone sees a product on Instagram, sends 'price?', and expects an answer before they scroll on. A WhatsApp marketing setup exists to catch that moment, find out what the person wants, stay in touch without being a nuisance, and make paying easy.
