How do you keep Black Friday customers after November?
By capturing a way to reach them and using it before the discount habit sets. Somebody who bought at 40% off returns at full price only if there is a reason that is not price.
In more detail
The window is the following six weeks. A useful follow-up — how to use the thing, what goes with it, a restock alert — reaches them while the purchase is still recent and before they file you under ‘wait for the sale’.
What to do about it
The preparation that matters happens in October. A store deciding its Black Friday plan in November is already reacting.
Discounting into a crowd where everybody is discounting wins volume and loses margin. The stores that do well have a reason to be chosen that is not the price.
Traffic spikes break the things that were nearly broken already — usually image weight and a checkout step nobody tested under load.
The mobile app angle
This is the one week where owning a notification channel pays for the year — reaching last year’s buyers costs nothing per message.
