Black Friday Email Strategy: What to Send Before, During, and After

Hayes Media, an email and SMS retention agency for eCommerce brands, plans Black Friday on one rule: most of the money is made before the sale starts. For Shopify and DTC founders, that means growing and cleaning the list in October, warming deliverability by sending to engaged subscribers first, opening VIP early access, and only then running a tight send rhythm through Cyber Monday.

Black Friday 2026 is Friday, November 27, and Cyber Monday is Monday, November 30. Below is the plan in calendar phases, with example emails, subject lines, and the discount math.

Two terms first. BFCM is the stretch from Black Friday through Cyber Monday. An engaged segment is the subscribers who have recently opened, clicked, or bought.

Why is the money in Black Friday email made before the sale?

Because the sale can only convert the list you already have, and only if your emails reach the inbox. Both of those, list size and inbox placement, are set in October and early November, not on the day.

List growth. Every subscriber you add before the sale gets the teaser, early access, launch, and last call. Someone who signs up on Black Friday gets one or two.

Early access capture. An early access signup turns a passive subscriber into someone who raised their hand for the sale. That's the group you can send the most to, because they asked for it.

Deliverability warm-up. Mailbox providers judge your sending partly on how recipients respond to it. If you jump from one email a week to the whole list twice a day, opens fall and complaints rise at the exact moment you need inbox placement most. So ramp up: send more often to your most engaged segment first, then widen the audience as engagement holds. A strong welcome series email matters here too, because it's the first impression every new pre-sale subscriber gets.

What should you send from now through early November?

Nothing that sells the sale yet. This phase is list growth, VIP early access signup, list cleaning, and fixing your flows.

Grow the list

Change your pop-up and landing pages to offer Black Friday early access as the reason to sign up. You don't need a deeper welcome discount to do it, because early access to the biggest sale of your year is already worth something. On its own site, Hayes Media's retention practice says, "We grow client lists 3.1x faster." That figure is published by Hayes on its own site, and Hayes has no third-party review profile.

Open VIP early access signup

Build one page where people opt in to early access by email, SMS, or both. Then email your engaged list and your best customers to invite them. SMS subscribers are the natural VIP group, since a text is the fastest way to tell someone the sale is open. Our guide to SMS marketing for eCommerce covers consent and list building.

Clean the list

Run a re-engagement campaign to subscribers who haven't opened or clicked in a long time. Anyone who still doesn't respond gets suppressed from BFCM campaigns. Remove hard bounces. Check that your domain authentication (SPF, DKIM, and DMARC) is set up.

Fix your flows

Check that your welcome, browse abandonment, cart abandonment, and post-purchase flows are live, accurate, and don't show a code that conflicts with the sale price. Our breakdown of Klaviyo email flows lists the core set, and these abandoned cart email examples show what the cart flow should say. Hayes works in Klaviyo for most accounts and has experience in most other email and SMS platforms, so the same checks apply wherever you send from.

What should you send the week before Black Friday?

Teasers to your engaged list, and early access for VIPs and SMS subscribers. This is the week of November 23.

The teaser gives the start date, what's included, and how to get in early. Send it to engaged segments, then a second teaser later in the week to people who opened but didn't join early access.

Early access then opens for VIPs and SMS subscribers before the public launch. In the plan below, that's Thanksgiving Day, Thursday, November 26. Keep the window short and real. If early access is open to everyone, it isn't early access.

How often should you email during the Black Friday sale?

Often enough that every subscriber who wants the sale hears about it, with frequency set by engagement. Your most engaged subscribers get the most sends. Your least engaged get the launch and the last call only.

Here is a rhythm you can follow, one line per day:

Thursday, November 26. Early access email and SMS to VIPs and SMS subscribers.

Friday, November 27. Launch email to engaged segments in the morning. A reminder later in the day to engaged subscribers who haven't clicked or bought.

Saturday, November 28, and Sunday, November 29. One email a day to engaged segments, each leading with a different product or collection. Leave out anyone who has stopped opening.

Monday, November 30. A Cyber Monday email in the morning, then a last call in the evening. Last call SMS to your SMS list.

Use SMS for the time-critical beats only. That means early access opening, launch, and last call. Not every email needs to become a text, and every extra text gives subscribers a reason to opt out.

Stop selling to people who just bought. Once someone orders, move them out of the sale campaigns and into your post-purchase flow.

What should you send after Black Friday and Cyber Monday?

An extension if you choose one, a thank-you, and then the post-purchase work that turns first-time sale buyers into second orders.

The extension. If you extend, do it once and say so plainly. If you call something the last chance and then extend it twice, you teach your list to wait for the next one.

The thank-you. A short email with no offer, thanking people for shopping with you.

Turning sale buyers into second orders. This is the step that decides whether the sale built anything lasting. Loyalty starts before the first order, in the whole buying experience: the site, the delivery, the packaging, and every email they got along the way. The second order is where that loyalty shows. So give first-time sale buyers a proper post-purchase sequence: shipping updates, how to use the product, then a reason to come back. These post-purchase email flow examples show the structure. For products people use up, a subscribe-and-save offer or a loyalty program invite gives them a reason to order again without waiting for the next sale. Our guide to eCommerce retention marketing covers the full system.

What do the four core Black Friday emails actually say?

Each has one job: the teaser sets the date, early access delivers on it, the launch states the offer, and the last call states the deadline. The 20% offer is a placeholder; use your own numbers.

1. Teaser

Subject: Black Friday starts the 27th. Want in early?

Our Black Friday sale starts Friday, November 27. VIPs get in a day early, on Thanksgiving. Join the VIP list and we'll send you the link the moment it opens. [Get early access]

2. Early access

Subject: You're in. The sale is open for you now.

As promised, you get first pick. Everything in the sale is live for you today, a day before everyone else. If there's something you've been waiting on, grab it before we open to everyone tomorrow. [Shop early access]

3. Launch

Subject: Black Friday: 20% off everything, through Monday

Our Black Friday sale is live. Take 20% off everything until midnight on Monday, November 30. No code needed. Start with our bestsellers or browse the full range. [Shop the sale]

4. Last call

Subject: Last call: the sale ends at midnight

This is the last email about our sale. It ends tonight at midnight, and then prices go back to normal. If you've had something in your cart, now's the time. [Shop before midnight]

What are good Black Friday email subject lines?

Plain ones that say the offer, the date, or the deadline. Here are examples for each beat:

Teaser. "Black Friday starts Friday. VIPs get in Thursday."

Early access. "Your early access link is inside"

Launch. "Black Friday is live: 20% off everything"

Cyber Monday. "Cyber Monday: the sale ends tonight"

Last call. "Last call, ends at midnight"

Thank-you. "Thank you for shopping with us this weekend"

Skip fake reply prefixes, all caps, and countdowns that aren't true.

How much should you discount for Black Friday?

Only as much as your gross profit math supports. Measure the sale in gross profit, not revenue, and only count orders the sale actually created.

Here's a worked example with made-up numbers. A product sells for $80 and costs $32 to make and ship, so each full-price order earns $48 in gross profit. At 25% off, the price is $60 and each order earns $28. To match the gross profit of 100 full-price orders ($4,800), you need about 172 sale orders.

Now say 40 of your sale buyers would have bought at full price in December anyway. On each of those, the sale gave away $20 of gross profit, or $800 in total. A sale that mostly pulls forward full-price orders just moves the same customers to a lower price. Our article on eCommerce unit economics walks through the full math.

Ways to protect margin while still running a real offer: give VIPs early access instead of a deeper discount, use a gift with purchase, build bundles, set spend thresholds, and leave your lowest-margin products out of the sale.

How do you protect deliverability during Black Friday?

Send the most to people who engage, keep complaints low, and make unsubscribing easy. Complaints come from people who didn't want the email, so peak frequency to unengaged contacts invites them.

Google is clear about the line. Its email sender guidelines say: "Keep spam rates reported in Postmaster Tools below 0.10% and avoid ever reaching a spam rate of 0.30% or higher." For senders of more than 5,000 messages a day, the same page says marketing messages "must support one-click unsubscribe, and include a clearly visible unsubscribe link in the message body."

In practice: set up Google Postmaster Tools before November, watch your spam rate daily through the sale, and if it climbs, cut back to your most engaged segment straight away.

What should you measure after BFCM?

Gross profit from the sale first, then the numbers that tell you whether it built the business.

Gross profit, not revenue. Revenue minus discounts, product cost, and fulfillment.

New versus returning buyers. How many sale customers were new to you, and what you paid to acquire them.

Second orders from sale buyers. Track how many first-time sale buyers come back and buy again over the following months, and compare them with full-price first-time buyers.

List growth. How many subscribers and SMS subscribers you added before and during the sale.

Unsubscribes and spam complaints by segment. This tells you which segments you pushed too hard.

What are the most common Black Friday email mistakes?

Starting in November. By then the list is the size it's going to be.

Sending the whole list from day one. Unengaged contacts at peak frequency bring complaints, and complaints hurt your inbox placement for everyone.

Texting every email. SMS is for the beats where timing matters.

Fake urgency. A last chance that keeps getting extended teaches people to wait.

Judging the sale on revenue. Revenue can rise while gross profit falls.

Forgetting the buyers after Monday. First-time sale buyers who never hear from you again have no reason to order a second time.

When does this Black Friday plan not apply?

If your brand doesn't discount, don't start because everyone else does. Brands built on full-price positioning, made-to-order products, or limited runs risk teaching full-price customers to wait for the next sale.

You can still use the week. Send a gift guide, launch a new product at full price, offer a gift with purchase, or keep your normal schedule and let your flows do their job. The pre-sale work still helps: a cleaner list and working flows pay off all year.

If your list is small or mostly cold, put the effort into list growth and flows, and run a simpler sale with fewer sends.
