WhatsApp broadcasts convert far better than email on average — but only when they're sent well. The gap between a campaign that performs and one that gets ignored usually comes down to a handful of avoidable mistakes.
The biggest one is sending to everyone. A broadcast to your entire list, regardless of purchase history or engagement, reads as spam even when the offer is relevant to some of them.
The second is skipping personalization. A message that opens with a first name and references a real order performs meaningfully better than a generic blast.
The rest come down to timing, frequency, and clarity of the call to action.
