@francoiss_cpt Under Section 69 of POPIA, direct marketing by electronic communication (which includes WhatsApp, SMS, and email) to a prospect who is NOT an existing customer is strictly opt-in: you may approach them ONCE to request their consent to receive marketing, provided they haven't previously withheld consent. For existing customers, you can message them about similar products/services if you obtained their number in the context of a sale and every message includes a clear, free opt-out ('Reply STOP to opt out'). Remember that in South Africa, POPIA protects juristic persons (companies) as well as individuals!
