Every year around this time, brands and marketers are told that Black Friday is starting earlier. The season is creeping into October, demand is pulling forward, you need to plan accordingly.
Wunderkind went looking for proof in six years of conversion data, fully expecting to find it. It isn’t there.
Demand is not being pulled forward. Planning around an earlier buying season means planning for a shift the data simply doesn’t show.
But something does move forward. And failing to recognize it is where brands leave revenue on the table.
Addressability Is What Shifts, and It Shifts Late
Email and phone opt-ins more than double heading into Cyber Week. People are getting into position to buy, and they already know what they want. They’ll hand you a phone number in late November that they would never have given you in July.
That sounds like good news. It’s a trap. The surge lands in the final ten days of the month, roughly November 21–30. By the time people volunteer their details, there’s no runway left to nurture them, segment them, or test creative against them.
At that point, instead of building an audience, you’re processing one.
The deadline that actually governs your holiday strategy comes before the surge. The audiences you want to nurture need to be addressable before it arrives.
More Than Half Your Black Friday Buyers Are Dormant, Not Lapsed
Here’s the number that reframes the season: 53% of returning BFCM shoppers have not converted at all that year.
Not churned. Not lost. Dormant. They browsed earlier in the year, went quiet, then came back in late November knowing what they wanted, and knowing it would likely be the best price of the year.
You already paid to acquire these people. They’re already in your CRM. But the catch? Your ESP may not recognize them when they return. They could be far outside an active cookie window, not logged in, or browsing on a new device or browser.
The revenue opportunity is already there. The question is whether you can recognize your own customers when they return to your site.
Usually, You Can't
Picture a shopper who visits in March, adds to cart, but doesn’t buy. Silence through October. Every cookie set during that first session expired months ago. She comes back on November 24. New anonymous session. Your ESP has her email on file, but no way to connect it to this visit.
This matters even more on mobile, which accounts for roughly 60% of BFCM revenue. In Safari, script-set cookies live for seven days at most, with some capped at just 24 hours. The traffic you pay the most for, during the week it costs the most, is also the traffic you have the shortest window to recognize.
The good news? This is also where the opportunity concentrates.
Across the Wunderkind network during Cyber Week 2025—650+ brands, 4 billion pageviews, 51 billion events, and $3 billion in tracked purchases—we saw 94 million unique phones and emails, six million of them brand new. Identification was 28% higher during Cyber Week than in October, as more qualified traffic arrived and more shoppers returned through owned sends.
And the stakes are significant: Wunderkind clients generate about 5.4% of their annual revenue in just 1.4% of the year.
Stop Buying Identity On ID Rate
If you’re evaluating an identity vendor this season, and you should hold us to the same standard don’t accept identification rate as the headline number. Every vendor defines it differently, and on its own, it tells you nothing about whether those customers were reachable or worth reaching.
Instead, ask for three numbers you can audit using your own data:
| Metric | What It Tests | |
| Reach | Part 1 sends per session | How many conversations you could start, resolution, a valid opted-in address, and behavioral triggering, all at once. |
| Quality | Conversion per Part 1 send | Whether those conversations were worth starting. Stops loose suppression from inflating the first number. |
| Truth | Revenue per session | Where both land, the only one of the three that can't be gamed in either direction. |
Part 1 sends appear in the numerator of one calculation and the denominator of the next, so they cancel out. That’s precisely why the final number holds up: a vendor can’t improve it simply by sending more messages to unqualified or unconsented leads.
Just make sure you use the same denominator throughout. Sessions, unique visitors, and pageviews will produce three different answers.
Three questions worth taking into every vendor call:
- Durability. What happens to identification after the cookie expires? Which of your identity sources still work at that point?
- Orchestration. Can you deterministically suppress someone already on my list after their cookie expires? How do you prioritize cost efficiency across channels—or will you simply encourage me to send more texts and emails?
- Support. What do you handle, and what’s left to my team? Who builds the emails? Who runs the tests?
Access Beats a Discount
Discounts stopped being the differentiator in 2025. About 27% of products were marked down during BFCM, while roughly 7% of the average product feed was already discounted in October. Campaigns naming a specific discount fell sharply last year, and the 20–30% discount tier shrank while sub-20% offers grew.
When everyone marks down, a discount gives shoppers little reason to give you their details early. Offering 20% off in a signup unit six weeks before BFCM asks someone to trade a phone number for something they expect to get anyway.
You don’t have to withhold the deal. You have to withhold the clock.
What that looks like in September and October:
- A VIP list with a specific access time, not “coming soon”
- Waitlists for the SKUs you already know will sell out
- Progressive capture—email first, then phone at the moment of intent
Build your addressable audience in the quiet months. October is the lowest capture month of the year, sitting directly in front of the ten most valuable days of the year.
Precision Beat Volume Twice Last Season
Two independent findings, same lesson.
First: only 3% of BFCM text sends were behavioral—triggered by something the shopper actually did. The other 97% were on-demand broadcasts. Yet that 3% drove roughly half of all text click revenue.
Second: at two collectibles brands, a single segment-only send to loyalty subscribers outperformed every full-list broadcast either brand sent that month.
That second finding is worth unpacking because the mechanic transfers. Both brands opened Black Friday early over SMS to loyalty subscribers only, then rebranded the onsite experience to match. The early-access story was visible to everyone, not just the people who received the text.
Two things happened: the loyalty sends became the highest-driving single sends of the month for both brands, and the onsite experience drove a wave of new loyalty signups before BFCM by giving non-members a reason to join.
Two details made it work. The CTA went to sign-in, not a product page, so the experience resolved identity before trying to sell. And the exclusivity wasn’t the discount. It was the timing.
The transferable lesson isn’t “run a loyalty program.” It’s this: take a segment with a reason to be treated differently, give it early access, and make that access visible to everyone else. Rank your audience using what you already know—repeat purchasers, high-AOV customers, recent browsers, broader SMS subscribers, and open Black Friday in waves, each with a specific start time.
One scheduling note: if you haven’t stood up text yet, this is the window. New programs need carrier registration and warm-up before you can send at volume, which can take weeks. You don’t want your first message landing in the busiest inbox of the year. If you already send, add access-based capture by November 1 and tag it separately so you can measure the difference in December.
Your Best Traffic of the Year Engages and Leaves
During BFCM, low-quality, bouncing traffic falls away. What’s left is a higher concentration of high-intent abandoners: people who view, add to cart, and leave. The interaction rate, the share of sessions that take an action but don’t buy—runs around 75%.
That’s why every behavioral module lifts during peak, not just the obvious ones. Click conversion rate versus October:
- On-demand text: +178.8%
- Welcome email: +90.8%
- Catalog email: +67.4%
- Abandonment email: +56.6%
- Abandonment text: +32.0%
The lift isn’t isolated to one part of the program. The whole portfolio rises together. Pausing everything except cart abandonment during peak means leaving revenue on the table.
And the welcome number carries a second implication: a capture point that goes live in November is worth roughly twice what it was in October.
The Most Underplanned Day of the Year Is the Sunday Before Cyber Monday
It isn’t quiet. About 12.0% of Cyber Week conversions land on Sunday—the third-highest day of the week, ahead of Saturday. It is, however, the single heaviest email send day of the year across our network. Heavier than Black Friday itself. Peak demand meets peak competition for the inbox.
So don’t go quiet. Go precise. Map what each person receives on Sunday across every channel. Suppress duplicates. Lead with your highest-converting channel and strongest creative, then let behavioral triggers respond to what shoppers actually do. Cut redundancy, not volume.
Almost nobody plans for Sunday specifically. That’s the opening.
Where to Hand AI the Wheel, and Where Not To
Peak week generates more decisions than any team can make by hand. Some should be automated. Some shouldn’t.
Let AI make the thousand small calls: which product to surface for each person, which price drop warrants a message, which of six modules fires first, and the ranking, sequencing, and recovery timing underneath it all. That’s a volume of decisions no team can match—and no individual decision warrants a human’s time.
Keep your hands on the decisions that are strategy: the offer and how deep it goes, when it opens and for whom, suppression rules, and which segments get early access. AI can optimize the decisions within those guardrails. The guardrails themselves are yours to set.
Our BFCM 2025 results point in the same direction: AI Catalog delivered 23% incremental reach and a 43% lift over classic Catalog, while 70% of clients testing AI Abandonment outperformed the classic setup. The opportunity is incremental: extending reach and adding revenue without cannibalizing existing email.
And one number for perspective: roughly 0.1% of ecommerce traffic currently arrives from ChatGPT. AI-driven shopping traffic is growing, and it will matter. But it isn’t what will decide your Black Friday in 2026.
Three Things to Do This Week
- Recognize: Pull your identification rate against conversions: Part 1 sends per session, then conversion per Part 1 send. If you don’t have both, you can’t evaluate an identity vendor—including us.
- Build: Stand up one access-based capture experience. Already sending text? Get it live by November 1. New to text? Start now—carrier registration takes weeks. Either way, tag it separately so you can measure the difference in December.
- Personalize: Audit your suppression strategy against Sunday, not Black Friday. It’s peak demand meeting peak noise, and almost nobody plans for it specifically.
Demand doesn’t move forward. Addressability does. Build it now, or inherit whatever November gives you.
