Black Friday, 8 a.m. Open your email inbox and you know exactly how your customers feel: dozens of discount subject lines stacked on top of each other, each one shouting louder than the last, most of them swiped away unread. On no other day of the year is the fight for attention harder.
That is precisely why Black Friday is the day your choice of channel decides everything. Rely on email alone and you are whispering in a packed stadium. Reach your customers on WhatsApp and you land where everyone is looking that morning anyway: the lock screen.
This guide takes you through the whole campaign, from four weeks out to the day after. Use it for Black Friday itself, or stretch it across a full Black Week.
Why WhatsApp is unbeatable on this one day
Three things make the difference. Visibility comes first: with a 98% open rate your message is not just delivered but actually seen, and on the biggest selling day of the year that is money in the till. Then speed: seconds pass between your message and a tap on your offer, not hours. And finally exclusivity: to a customer, a WhatsApp list feels like an inner circle rather than a mailing list.
On Black Friday it is not the best offer that wins. It is the offer that gets seen.
Four weeks out: build your VIP list
The campaign starts with the recipients, not with the discount. From the end of October you collect sign-ups deliberately, with a promise that fits the occasion: “WhatsApp contacts get our Black Friday offers first.”
In practice that means a QR code at the till, a note on your website, a line in your email signature. Every contact confirms by double opt-in, which keeps the whole thing GDPR-compliant. Starting early matters more than anything else: wait until Black Week to begin collecting and you will have nobody to write to on the big day.
One week out: build tension, do not spoil it
Now you start warming people up. You are not giving everything away, but you make it clear that staying tuned pays off:
“Next Friday is the day. All we will say for now: our best offer of the year is on exactly the products you ask about most. You will hear it here first.”
Two days out you follow up, ideally with a concrete preview of one single product. Countdown promotions let you build momentum that points the whole list at Friday without wearing anyone out beforehand.
The day itself: two messages, no more
The biggest temptation on Black Friday is to send too often. Resist it. Two messages are enough if they land.
Morning, at the start (8 to 9 a.m.):
“Here we go: 30% off the entire autumn collection, today only. As a WhatsApp contact you get in a full hour before everyone else - here is your link.”
Evening, last chance (6 to 7 p.m.):
“Quick update: the most popular sizes are running low. The promotion ends at midnight, and after that normal prices are back.”
Both messages follow the same pattern. A concrete offer, a clear deadline, one single thing to do. Not five links, not a flood of products. If you want to show more, link to a single overview page.
After the day: turning bargain hunters into regulars
The most common mistake comes after Black Friday: radio silence until Christmas. And yet you have just gained a stack of new contacts and fresh buyers, and there is no more valuable moment for building loyalty.
In the week that follows, send buyers a message with nothing to sell. A thank you, a care tip for what they bought, a note about how exchanges work. The new sign-ups who did not buy go into your regular WhatsApp newsletter, where you give them something genuinely useful in the weeks up to Christmas. That is how a discount frenzy turns into a channel that carries you all year.
A word on opt-outs. Yes, a few pure bargain hunters will leave you after Black Friday. That is nothing to worry about; it is a natural clear-out. What remains are the contacts who are genuinely interested in your business, and those are exactly the people who carry your Christmas trade.
Your checklist at a glance
- From four weeks out: collect sign-ups with an exclusive promise
- One week out: send the teaser, two days out the countdown
- On the day: the starting gun in the morning, last chance in the evening - and nothing more
- Afterwards: a thank you to buyers, a welcome series for new contacts
