Can I stop advertising to existing customers?
Yes, with a customer match exclusion — and for one-off products it is worth doing.
The short answer
Yes, with a customer match exclusion — and for one-off products it is worth doing.
Upload your customer list and exclude it from prospecting campaigns so budget goes to new demand.
For consumables and repeat-purchase categories, do the opposite: target them deliberately, because a returning buyer is usually your cheapest order.
