Between 9 and 10 a.m. Eastern Time on Black Friday 2024, Klaviyo brands sent more than 420 million emails in a single hour. Across the whole season, email and SMS drove $3 billion+ in attributed revenue across 157,000+ brands — and 15,000+ of them had their best sales day ever. Email is not a supporting act during Cyber Week; it is the main stage. Last updated: October 2026.
For small stores the stakes are even clearer: Omnisend found that 20% of SMB ecommerce stores generate roughly a third of their annual orders during Cyber Week. One well-planned sequence, drafted in an evening with AI, is the highest-return writing project of your year.
This guide gives you the complete flow: a dated 7-email calendar for 2026, copy notes for each send, a subject-line bank, segmentation rules, send times, and the master prompt that drafts all seven emails in one pass. It sits between the other two pieces of the system — the Black Friday ad copy that fills the top of the funnel and the landing page every message links to.
What is a Black Friday email sequence?
A Black Friday email sequence is a planned series of sends — usually five to eight — that carries one offer from teaser to deadline across the Cyber Week window. Each email has a job: warm up, open early, remind, convert, rescue. Written well, it sells the same offer five times without boring the list.
The word that matters in that definition is planned. Random one-off blasts during the busiest inbox week of the year get buried. A sequence works because each send is positioned: what the reader heard yesterday determines what they need to hear today.
Seven is the sweet spot for a small store. Fewer sends waste the season's built-up intent; more send unsubscriptions up without adding revenue. Every number and date below is built for Black Friday 2026 on Friday, November 27.
The data case for email this season
| Number | What it measures | Why it matters for your sequence |
|---|---|---|
| $3B+ / 157,000+ brands | Klaviyo attributed revenue, BFCM 2024 | Email carries the season at every store size |
| 18B+ messages | Delivered across Klaviyo brands, BFCM 2024 | Inboxes are crowded — subject lines and send times decide survival |
| 420M+ emails, 9–10 a.m. ET | Single busiest send hour, Black Friday | Morning sends are the industry default; plan around them |
| +20% YoY revenue | Brands that added SMS to email (Klaviyo) | Pair the sequence with an SMS mirror on peak days |
| 68% | US shoppers whose top BFCM priority is discounts (Omnisend) | Lead with the number, not the brand story |
| 70.22% | Average cart abandonment (Baymard) | Recovery sends inside the sequence are not optional |
Two more numbers shape the writing itself. Klaviyo's AI analysis of BFCM 2025 found +68% more AI-powered messages year over year and +71% more revenue from messages with AI-driven recommendations — the tooling is now table stakes. And average order value rose from $164 to $215 between 2024 and 2025, which is why the sequence below sells thresholds and bundles, not just percentages.
The dated 2026 calendar: every send planned
No major publisher prints a dated grid, so here it is — every send for Black Friday 2026, with goal, segment, time and the metric that tells you it worked. Times are the recipient's local time unless marked ET.
| # | Send date | Goal | Segment | Send time | Success metric |
|---|---|---|---|---|---|
| 1 | Wed, Nov 18 | Tease the date | Whole list | 10 a.m. | Open rate |
| 2 | Sun, Nov 22 | VIP early access | Top 10% by spend | 9 a.m. | Revenue per recipient |
| 3 | Thu, Nov 26 | "Doors open tomorrow" | Whole list | 7 p.m. | Click rate |
| 4 | Fri, Nov 27 | Launch day | Whole list | 8–9 a.m. | Revenue per recipient |
| 5 | Fri, Nov 27 | Last call, evening | Non-openers + non-clickers | 7 p.m. | Revenue per recipient |
| 6 | Mon, Nov 30 | Cyber Monday final | Whole list | 8–9 a.m. | Revenue per recipient |
| 7 | Wed, Dec 2 | Extended close + thanks | Whole list | 10 a.m. | Revenue + unsubscribe rate |
Then block one hour on Thursday, December 3 for the post-mortem: which send earned the most per recipient, which subject line won, what the sequence earns next year. That review is where next season's advantage comes from.
The morning slots are deliberate. Klaviyo's send data shows 9–10 a.m. ET is the peak volume hour, while orders actually crest at 12–1 p.m. ET — your morning email lands while shoppers are planning, right before lunchtime buying.
The seven emails, one by one
Email 1 — Teaser (November 18)
Job: borrow attention without spending the offer. One screen: "Something big lands Friday, November 27." Tease the tier if you dare ("our biggest discount this year"), invite a calendar mark. Klaviyo's example set includes Little Beast's pre-Black Friday "get ready" send doing exactly this — and the forecast data says browsing already climbs about ten days out, so the teaser rides real intent.
Email 2 — VIP early access (November 22)
Job: make your best customers feel early. Open the sale 24 hours ahead for the top 10% by lifetime spend, with a code or a members-only link. Omnisend's swipe file documents a VIP early-access email with a 65% open rate — exclusivity cuts through when nothing else does. This is also the send that rewards the 43% of consumers who subscribe specifically for exclusive discounts.
Email 3 — Launch eve (November 26)
Job: prime tomorrow. "Doors open at midnight" or your real launch hour, the tier, the deadline, and one hero product shot. Short — under 80 words. The reader should finish it knowing exactly what happens tomorrow and when.
Email 4 — Launch day (November 27)
Job: land the offer in full. The discount in line one, the stack (threshold, bundle) in bullets, real deadline, one button. Klaviyo's examples show Shinola running tiered launch offers ("spend more, save more") to lift order value rather than racing to the deepest cut — the same logic behind the $215 average basket.
Email 5 — Last call (November 27, evening)
Job: honest urgency to non-buyers. Subject: hours remaining. Body: the offer, the cutoff, the practical answers (shipping cutoffs, returns). Nēmah's last-chance send in Klaviyo's library is the model — calm, specific, and final. No invented sell-out claims.
Email 6 — Cyber Monday final (November 30)
Job: second bite for holdouts. Same offer or a Cyber Monday twist, framed as the final window. Expect the busiest inboxes and the most expensive ads of the season — this send converts the people your paid media couldn't afford twice.
Email 7 — Extended close and thank-you (December 2)
Job: catch stragglers and end the season on brand. Either "extended 48 hours, genuinely the last time" or a clean thank-you with a post-season nudge. Klaviyo's case studies report BFCM email programs delivering +74% and even +274% revenue lifts — the final sends are where hesitant buyers finally move.
Subject lines that survive the busiest inbox of the year
Subject lines under about 45 characters, numbers and dates over adjectives, and a preview text that adds information instead of repeating the subject. Here is the bank, mapped to the calendar:
| Send | Subject line | Why it works |
|---|---|---|
| 1 | Something is coming November 27 | Curiosity plus a date |
| 1 | Mark the date: 11.27 | Five words, zero effort to process |
| 2 | Early access starts Sunday | Exclusivity, no discount leak |
| 2 | Your early access code is inside | Utility — opening earns something |
| 3 | Doors open tomorrow at midnight | Concrete time, no vague hype |
| 3 | Tomorrow: our biggest discount of the year | Stakes plus a deadline |
| 4 | It's live: 20% off everything | Announcement, number, first word is the news |
| 4 | Black Friday starts now | Works because the list was warmed by 1–3 |
| 5 | 6 hours left on 20% off | Countdown + number |
| 5 | Last call: ends 11:59 p.m. | Specific, checkable deadline |
| 6 | Cyber Monday: final 24 hours | Named day + window |
| 7 | Extended by 48 hours (last time) | Permission to buy late, honest cap |
Test two variants per key send on a 20% split, roll the winner to the rest. On peak days, brands following the "three emails plus two SMS" cadence roughly doubled revenue, per the benchmark from merchant Ezra Firestone that Klaviyo cites — subject variants are how you make each of those sends pull weight.
Who gets what: segmentation that protects the list
Seven sends to one undifferentiated list works — barely. Four segments make the same seven emails earn more:
- VIPs (top 10% by spend): early access on November 22, site-only exclusives. Beekman 1802's VIP example in Klaviyo's library ran the offer site-wide but framed it as insiders-first.
- At-risk (no purchase in 90 days): one deeper-tier variant on Cyber Monday — your last excuse to re-reach them before the annual list cleanup.
- New subscribers (captured pre-season): education first. They joined for the discount; email 1 doubles as their introduction to what you sell.
- Cart and browse abandoners: automated triggers, not calendar sends. Little Sleepies cut trigger delays from one hour to 30 minutes and moved abandonment sends from every 14 days to daily during the season — speed matters more than polish here.
The abandoner track is where the sequence pays its rent: Baymard puts average cart abandonment at 70.22%, and the top reason (beyond window-shopping) is 40% citing extra costs too high — so your recovery send should lead with the shipping threshold, not a bare reminder.
The master prompt for the whole sequence
Paste this into your AI tool with your details in the curly-brace slots. It drafts all seven emails, aligned to the calendar above, in one pass:
You are an ecommerce email copywriter. Draft my 7-email Black Friday 2026
sequence for {store, category, audience}. For EACH email output: send date
and goal, segment, subject line (max 45 characters) plus preview text, hero
copy (max 60 words), three bullet benefit lines, button text, and one PS line.
Sequence:
1. Nov 18 teaser — something is coming
2. Nov 22 VIP early access — exclusive first look + deadline
3. Nov 26 launch eve — doors open tomorrow
4. Nov 27 launch day — offer stack + real deadline
5. Nov 27 evening last call — honest countdown
6. Nov 30 Cyber Monday — final offer
7. Dec 2 extended close + thank-you
Offer: {discount, threshold or bundle}. Rules: western numerals only,
no fake scarcity, only real deadlines and stock, no personal-attribute
callouts, mobile-first preview text. Output as a table.
Then run the humanize pass yourself: read every send aloud, delete anything that sounds like a robot celebrating, and verify every claim, price and cutoff against the store. If you want a tool that keeps the whole sequence — drafts, variants, calendar — in one workspace, ArWriter's auto-writer is built for exactly this, from $4.99/month. Draft your sequence here.
How a Rotterdam skincare brand wrote 7 emails in one evening
Eline Verhoeven runs a two-person natural skincare brand from Rotterdam. Two years ago her entire Black Friday plan was two emails, written in a panic on the morning of the sale. Revenue that weekend: unremarkable, and she spent it apologizing to support.
This season she tried the calendar above. One evening drafting with the master prompt, one morning of edits, seven emails scheduled and the abandoner triggers tightened to 30 minutes. Her list is 8,400 subscribers — modest, engaged. The VIP send opened at 58%, the sequence averaged 44% opens across the seven sends, and attributed revenue came to $21,300, with unsubscribes under 0.4%.
Her takeaway matches the data: the calendar did the work. "I stopped writing what felt inspiring and started writing what the reader needed to know on that date," she says. AI handled the volume; the sequence handled the timing.
Two weeks out: deliverability and list prep
Nothing in this guide survives a blocked sender. Two weeks before the first send:
- Clean the list. Remove hard bounces and sunset subscribers inactive for 12+ months. Volume spikes punish dirty lists at the exact wrong moment.
- Ramp your sending. If you usually send weekly, move to twice weekly now, then to near-daily by November 24 — a 2× to 4× ramp over two weeks signals a legitimate seasonal pattern instead of a sudden blast.
- Authenticate and warm. Confirm SPF, DKIM and DMARC, and keep the ramp going through the month. Klaviyo's deliverability guide for Black Friday covers the technical setup in depth.
- Grow before the flood. Browsing surges roughly ten days before the sale — put the opt-in in front of it. The offer is easy: 43% of consumers subscribe specifically for exclusive discounts, so that is the promise to make.
- Stage the SMS mirror. Brands that added SMS saw +20% year-over-year revenue in BFCM. Collect consent now, not on November 26.
When the cart is still abandoned
Calendar emails sell the offer; triggers rescue the hesitation. On Black Friday itself, set the abandonment trigger to 30 minutes, then two hours, then a final morning-after send that leads with the shipping threshold and the deadline.
During a sale this hot, things sell out — which is a conversion moment, not a dead end. A back-in-stock flow with AI-written restock lines captures demand your competitors write off, and the back-in-stock email guide covers the full setup.
Email content itself can borrow proof: real customer photos and quotes inside the launch sends lift clicks, and a UGC system for ecommerce keeps the library full without new photoshoots.
FAQ
When should you send Black Friday emails?
Send the heavy sends between 8 and 10 a.m. in each recipient's local time, and evening last-chance emails between 7 and 9 p.m. Klaviyo's data shows 9–10 a.m. ET is the single busiest send hour — more than 420 million emails in one hour on Black Friday 2024 — while orders peak at 12–1 p.m. ET.
How many Black Friday emails should I send?
For a small store, seven sends across the season is the sweet spot this guide builds on. On peak days, brands that sent three emails plus two SMS messages roughly doubled revenue, per the benchmark from merchant Ezra Firestone that Klaviyo cites. Under-sending is the bigger risk: shoppers expect more mail during Cyber Week.
What are the best Black Friday email subject lines?
Short, specific and dated: lead with the number and the deadline, under about 45 characters. "20% off ends tonight" beats "Our biggest sale of the year" because it tells the reader exactly what happens. Omnisend's swipe file shows VIP early-access subject lines hitting 65% open rates when exclusivity is explicit.
What do you write in a Black Friday email?
One offer, one deadline, one button. State the discount in the first line, show the products or categories it covers, answer the practical questions — shipping cutoffs, returns, codes — and close with a clear deadline. A short PS line restating the deadline is the most-read line in most ecommerce emails.
Should you send a Black Friday teaser email?
Yes — send it about a week before launch. Klaviyo's forecast shows browsing surges roughly ten days before Black Friday, so a "something is coming November 27" email rides existing intent instead of creating it. Keep it short, tease the discount tier, and invite subscribers to set a reminder or join early access.
What is a good open rate for Black Friday emails?
Context matters more than a single figure. Inboxes are flooded, so a typical campaign might earn less than your yearly average — but exclusivity still cuts through: Omnisend documents a VIP early-access email with a 65% open rate. Track your own trend line across the seven sends instead of chasing a universal benchmark.
When do Black Friday email campaigns start?
Planning starts in October; audience-facing sends start mid-November. Klaviyo's data puts roughly half of seasonal revenue inside a 16-day window, with browsing climbing about ten days before the sale. This calendar begins Wednesday, November 18 and closes Wednesday, December 2; everything before that is preparation.
What is a last-chance email?
The final send before your offer expires — usually late on Black Friday or Cyber Monday evening. It restates the exact deadline, the discount and the practical details in as few words as possible. Klaviyo's example library singles out last-chance sends as top revenue earners; the best ones are calm, specific and honest about the cutoff.
Should Black Friday emails go to your whole list?
Yes for the launch sends — this is the one week a year when even dormant subscribers expect mail. But segment the edges: VIPs get early access, 90-day inactive subscribers get one re-permission chance, and hard bounces are removed before the first send. Volume spikes punish dirty lists at exactly the wrong moment.
Your next step
Open a calendar, copy the seven-row grid above, and schedule the dates tonight. Then run the master prompt, edit for one morning, and lock the sends. The sequence is the cheapest revenue asset you will build this season — it works the list you already paid for.
After December 2, close the loop: a quick satisfaction survey tells you what to fix before the next sale, and a plan for responding to negative reviews with AI protects the reputation a busy week can scratch. Then point next season's ads at a fresh Black Friday landing page — the sequence works best when every email lands on a page built to close.
ArWriter drafts the whole flow — emails, subject variants, landing copy — from $4.99/month. Write your sequence tonight.
