An opt-in is the difference between a broadcast people read and a number people block. Here is where to collect consent, what to write down, and what to do the moment somebody replies STOP.
Consent on WhatsApp is simpler than it sounds. The customer has to know who is asking, what they will get, and how to stop it.
The best opt-in is taken at a moment when the customer already wants to hear from you.
One question, asked once, at the end of a conversation that already went well.
If a customer asks why you are messaging them, you should be able to answer in one line, with a date.
Consent is not a one time event. People stay opted in when the messages are worth reading.
On a call with the Abuja team we wire the tick boxes, the QR code and the consent record into your account, free during setup.
