10 ways retail and beauty brands win Black Friday on WhatsApp in 2026

TL;DR: The brands that win Black Friday on WhatsApp build their list in September, test in October, open the weekend with their VIPs, let every buyer recruit the next subscriber, run a schedule, and watch the first three hours of every send. Discount will do some of the work, but on WhatsApp it should never be the only thing in the message. Here are the ten moves that separate double-digit ROAS from the unsubscribe button.

Black Friday 2025 was bigger online than any before it, and most of your emails went unopened. Shoppers in the UK spent £3.8bn online across the four days from Black Friday to Cyber Monday, up 4.6% on the year before, while US Cyber Week reached $44.2bn. Email is not keeping pace: on Black Friday 2024 a single provider, SendGrid, processed more than 1bn emails an hour, Salesforce reported opens down 4.9% across that Cyber Week, and typical Black Friday email opens sit at 20 to 25%. WhatsApp, with more than 3bn monthly active users and read rates above 90%, is where one major UK beauty brand generated 6% of its annual revenue from 1% of its customer base. This piece is for the CRM, digital and ecommerce leaders who own that outcome: ten specific things to do, in the order to do them, so that 27 November 2026 becomes the most profitable weekend on your calendar.

If you want the month-by-month detail behind each move, our Black Friday Guide covers September and October set-up (Part 1), November launch and conversion (Part 2) and the December review (Part 3).

1. Treat it as Black Month, and start building your list this week

The strongest lever you control ten weeks ahead is the size of the opted-in audience you have on the Thursday night before. A list built in the last week of November costs more and converts less, because nobody on it has had time to warm up. The beauty brand in the introduction added more than 5,000 WhatsApp opt-ins in a single month in the run-up to Black Friday with only three sources: a web layer on the site, which drove most of the traffic, reminders in email, and its social bios. Most brands have rather more sources available: checkout and order confirmation, a "track your order on WhatsApp" link in post-purchase emails, QR codes in your shops and on packaging, click-to-WhatsApp ads and referrals. Every source must capture an explicit WhatsApp marketing opt-in, with a record of it: a phone number collected at checkout or a request for delivery updates does not silently become a marketing subscription, and email or SMS consent does not carry across. Test the opt-out journey as carefully as the sign-up. If you are not live yet, the channel is not the bottleneck: the brand above was growing its base and running its welcome journey within a fortnight or three of onboarding with Merx. The incentive does not need to be a discount at all. Money off (10 to 25% on a first order), free delivery, or £5 to £10 off with a minimum spend are the three we see most often, but first access to a limited edition, a creator's tutorial before it goes public, or a personal shade or size consultation in chat cost less and attract the customer you want to keep. Whatever you choose, make the promise Black Friday flavoured ("be first to hear about our biggest sale of the year"). The list you build in September is the revenue you bank in November.

2. Let the welcome flow deliver the promise and do your segmentation

The welcome message is the first part of the campaign, so deliver on whatever the sign-up promised: if you promised early access, say when it opens, and explain what messages will follow and how to stop them. Then use the one moment when every new contact is paying full attention to ask the questions that decide which Black Friday campaign they receive: a category interest ("brows, complexion or skincare?"), whether they are shopping for themselves or for gifts, a date of birth, a location if you have shops, and an email address to link the contact to your CRM. Keep the questions short and optional, and present the incentive after them, because the discount code is the reason people answer. Then segment straight away, because new customers, VIPs, high spenders, low spenders and lapsed buyers behave completely differently on Black Friday and should never receive the same message. Message new subscribers promptly, because one analysis of previous Black Friday seasons found that subscribers who heard from the brand soon after joining spent around three times more than those left to wait.

3. Use October to test

The brands that look effortless on Black Friday have already made their mistakes in October, whilst nobody was watching. Customers rarely switch into buying mode until the day itself, yet they will quite happily engage with a new channel in the weeks before, and that engagement tells you which incentives, formats and send times to trust. Use the weeks between now and the end of October to run three or four smaller campaigns to the segments you built in the welcome flow, with the AI agent from move four answering the replies: a new product launch, a secret sale for subscribers only, a piece of useful content, a private WhatsApp event, or a booking prompt if you have shops or services. Halloween and Singles' Day on 11 November are convenient excuses to run a promotional message without discounting your hero products, and they double as a dress rehearsal for send time and creative. Test one variable at a time: text against an image, a percentage discount against free delivery, a 9am send against a 7pm send, one button label against another. Track replies, button clicks and revenue per recipient rather than opens, because on WhatsApp opens are close to universal. By the last week of October you should know the best incentive for each segment and the send time that earns the highest click-through, and your Black Friday plan should be written from that evidence.

4. Give your AI agent a job description before the rush

Black Friday is the weekend your customers ask the most questions and your team has the least time to answer them. An AI agent trained on your catalogue, promotion terms and brand guidelines can carry that load, but only if you have decided what it should do before the first campaign goes out. Start by listing the questions you know will come: which shade or size, whether the code stacks with the sale, where an order is, what the returns window is, and what to buy for someone else. Give the agent the product feed, the terms and the tone of voice, then let it run on the October campaigns and review the questions it could not answer. Test the difficult scenarios too: ambiguous requests, unavailable products and situations that need a person, checking that the agent asks for clarification when it should and hands over clearly, which is why simulation, not deployment, is the critical step. An agent that answers rather than announces is one of the three mechanics behind the results our clients report, alongside contactability above 85% against roughly 30% for email and first-party data captured in chat from 99% of subscribers. Make the human handoff obvious, so that a frustrated customer reaches a person in one tap. And check your Meta quality rating and template approvals in the week before, because a template rejected on the Thursday night is a campaign that never leaves. A campaign is only ready when the team can support the conversation it starts.

5. Open the weekend with your VIPs

Your most loyal customers should never find out about your sale at the same time as a stranger. The best-performing Black Friday campaigns we see start a few days early with a message to the top segment only: early access, a private link, and a reason to feel chosen. Something as simple as "Hi Sarah, you're one of our VIPs, so here's 24 hours of early access to our Black Friday sale before anyone else" does three things at once. It rewards loyalty at almost no cost, it creates a first wave of revenue before the noise starts, and it gives you a clean read on your offer with your warmest audience before you send it to everyone. Make the opening and closing times explicit and test the early-access link before you announce it, because a link that lands on a locked page burns the goodwill it was meant to build. Industry analysis of previous seasons points the same way: early access beats last-day reminders, so start telling your whole list what is coming a fortnight or three ahead, even if the VIP window itself is 24 hours. Early access is the simplest form of exclusivity, but not the only one: a limited edition or colourway reserved for subscribers, a gift-wrapping or engraving service that is free for VIPs, an extended returns window through January, or a live styling session with your team all reward loyalty without a deeper discount, and on WhatsApp they feel personal rather than manufactured.

6. Make the offer interactive

A discount code in a message is an email with a green icon. The campaigns we see earn the most engagement on WhatsApp ask the customer to do something before they reveal the reward. A mystery discount, unlocked when the customer taps to reveal it, turns a promotion into a small game. A "choose your perk" message, offering free delivery, a gift, gift-wrapping or an extra 10%, gives customers control and tells you what each segment values. The reward does not have to be money off. Exclusive content works, such as a get-ready-with-me video from a creator your customers already follow, a founder's guide to building a winter routine, or a behind-the-scenes look at next season, unlocked in the chat before anyone else sees it. So does customisation: a monogrammed or engraved version of a bestseller, or a shade-matched or size-matched pick the agent finds for them, which can lift order value and the sense of being looked after at the same time. A personal shopping conversation, where the agent builds a bundle around what the customer already owns, lifts order value without lifting the discount, as long as a single-product option stays open for anyone the bundle does not suit. A gift finder is the flow that turns a browsing question into an order, because it solves the problem most shoppers have in late November: open with "Who are you buying for, and what would you like to spend?", then suggest three picks with a reason for each. Interaction turns a promotion into first-party data.

7. Layer a referral incentive on top of the offer

Every Black Friday buyer knows someone who would like the same thing, and on WhatsApp the introduction is a forward. Add a referral mechanic to your best offer: the buyer gets a small reward when a friend joins the channel or places a first order, and the friend gets the same welcome incentive everyone else does. Keep it to one tap, with a personal link or code the customer can share straight into a family group chat, because the moment of pride is right after the purchase and it fades by the evening. The reward for the referrer does not have to be money off either; early access to the next drop, a gift-wrapping upgrade or a place on a limited-edition waiting list all work, and they are cheaper than a discount stacked on a discount. Two guardrails apply. Give a referred friend the reward only once they have opted in, so the list you grow is a list you can message, and cap the reward per referrer so a single enthusiast does not become a discount channel. Run it properly and the weekend leaves you with a larger opted-in list in December than you had in November, built from the people your best customers already trust; we have written about how to grow referrals without cannibalising sales.

8. Show the range

Industry analysis of previous Black Friday seasons found that images showing several products earned more engagement than a single product shot, and the reason is simple: most people opening a Black Friday message do not yet know what they want. A single hero image asks them to say yes or no to one thing; a picture of the edit, six products on a plain background with the prices visible, invites them to browse, and browsing is the state a customer is in when they add a second item. On WhatsApp the format helps: a carousel lets a customer swipe through a curated selection without leaving the chat, with a button under each card that lands on that product rather than the homepage. Build the edit for the segment, so the gift shopper sees a gift edit and the skincare customer sees skincare, and keep the copy short, because on this channel the picture does the selling and the text tells them how to buy. Use the hero shot for the launch and the limited edition, where one product is the point; for the sale itself, show the range.

9. Run the weekend as a schedule

Black Friday on WhatsApp is won with a handful of well-timed messages. The rhythm we see work best starts on the Wednesday or Thursday with the VIP early-access message. On Friday morning the main campaign goes out, one version per segment, each with its best-tested incentive. On Saturday a short check-in goes only to people who clicked but did not buy, with a different angle. On Cyber Monday, 30 November, a genuinely different offer goes to everyone with a real closing time, because the customer who ignored a percentage discount may respond to a bundle or a gift. Set a contact cap across campaigns and automations, two messages at the least and six or seven at the most across the whole week, coordinate it with email and SMS so nobody hears from you through three channels in the same hour, and drop anyone who has bought from the reminder audiences for that purchase. Two automations should run underneath for the whole period. The first is abandoned-basket recovery, which on WhatsApp can ask what is blocking the purchase ("would help with sizing or delivery make choosing easier?") before it adds another discount; stop when they buy, opt out or say they do not need help. A UK wellness brand we work with converted 17% of abandoned baskets through conversation, against 5% for email. The second is back-in-stock alerts, welcome as long as they link to the exact size or shade requested, never imply stock is reserved unless it is, and pause the moment the product sells out again. Do not send "last chance" reminders every few hours: nearly every message is already read, and in our experience, as in published analysis of previous seasons, final-call messages add very few sales while increasing blocks and opt-outs.

10. Watch the first three hours, then measure what changed

The first three hours after a send tell you more than the end-of-day report. Set up a simple live monitoring desk for each campaign and watch five numbers as they come in: delivery rate, because a failure rate above 10% usually means a template, segment or send-cap problem, or a list that needs cleaning. Then replies and reactions, a soft conversion signal; button clicks by position and wording; drop-off points in any multi-step flow; and unsubscribes, because a spike means the tone, frequency or relevance is wrong. Give one person the authority to pause a campaign when customers are running into trouble. Part 2 of our guide has the full monitoring checklist. The benchmarks we see from brands running this well are engagement of 80 to 90%, click-through of 60 to 75%, click-to-sale conversion of 5 to 10%, and a channel return of 10 to 20 times the cost of the campaign; anything below those ranges is a signal to change the audience, the creative or the timing before the next send. Attribution should be in place before the weekend: UTM parameters on every link, a unique code per channel, a defined attribution window, and profile matching so a WhatsApp number and an email address resolve to one customer and one order is counted once across channels. Read revenue net of discounts, returns and message costs, because clicks diagnose a campaign but do not prove it made money. Where you can, hold out a random slice of the eligible audience that receives nothing, so you measure the sales WhatsApp added. The same test, run on the final reminder alone, settles whether it earns its place.

The short version

Black Friday on WhatsApp is a conversation, not a broadcast with a better open rate. Pick the moves that fit your customers, then give each campaign an audience, an owner, a success measure and a clear reason to stop. The beauty brand in this piece ran the core of this playbook ahead of Black Friday, early access for its loyal customers and offers personalised by segment, and 1% of its base on WhatsApp produced 6% of its annual revenue. There are fewer than 11 weeks to go.
