Black Friday & Cyber Monday email subject lines: 100+ examples (2026)

Black Friday and Cyber Monday email subject lines that get opened in 2026

The best Black Friday email subject lines put the offer or the deadline in the first 30–40 characters, name one concrete detail (a percentage, a product, a time) and match the stage of the campaign: a teaser in mid-November does not read like a last-chance email on 1 December. Black Friday 2026 falls on Friday 27 November and Cyber Monday on Monday 30 November, so most brands will send six to ten emails between 16 November and 2 December.

This page gives you 104 ready-to-adapt subject lines sorted by campaign stage, a 2026 send calendar, ten subject line and preheader pairs, and the words and habits that push Black Friday emails into spam. For the wider campaign strategy (offers, list preparation, design), read our guide on making the most of Black Friday with email marketing.

Key takeaways

• Lead with the offer or the deadline: "30% off everything, today only" beats "Our biggest event of the year".
• Write a different subject line for each stage: teaser, early access, launch, reminder, Cyber Monday, last chance, thank-you.
• Use the preheader to add the second detail (code, end time, free shipping threshold) instead of repeating the subject line.
• One emoji is plenty, and never in place of the offer.
• Keep every promise in the subject line true: a misleading subject line is a legal risk in the US and EU and a fast way to collect spam complaints.

When should each Black Friday email go out in 2026?

Send your Black Friday emails in stages, from a teaser two weeks out to a final reminder on 1 December, and write the subject line for the stage, not for the event in general. Here is a realistic calendar for 2026:

You don't need every email on this list. A small shop can do well with four: early access, launch, Cyber Monday and last chance. What matters is that each subject line tells the reader what changed since the last email.

What makes a Black Friday subject line work?

A Black Friday subject line works when it is specific, short enough to read on a phone and honest about the offer. In practice:

1. Offer first. Put the number or the benefit at the start: "40% off boots" before "for Black Friday".
2. Short enough for mobile. Mobile inboxes cut long subject lines, so keep the key information in the first 30–40 characters. Our guide to the best email subject line length explains the limits per inbox.
3. One concrete detail. A time ("ends at midnight"), a product ("the 2026 winter jacket") or a figure ("free shipping over $50") is more convincing than "huge savings".
4. Your brand in the sender name, not the subject line. The From name already tells readers who you are, so the subject line can spend its characters on the offer.
5. Stage-appropriate urgency. Save "last chance" for the last email. If every email says it, none of them mean it.

Teaser subject lines (before Black Friday)

Teaser subject lines create anticipation without revealing everything; the best ones still give a date or a hint so the email is useful on its own.

1. Black Friday starts 27 November. Here's a hint
2. Mark your calendar: our sale opens Friday at 8am
3. Something big drops on 27 November
4. Your Black Friday wish list starts here
5. Psst… our lowest prices of the year are 10 days away
6. Black Friday is coming. Want first pick?
7. Sneak peek: 3 products going on sale Friday
8. Don't buy that yet. Wait until Friday
9. Our Black Friday plans (you'll like these)
10. The countdown starts now: 7 days to Black Friday

Early access and VIP subject lines

Early access subject lines reward subscribers for being on your list, which is also the best reason you can give someone to stay subscribed.

11. You're in: early access starts now
12. VIP only: Black Friday prices 48 hours early
13. Subscribers shop first. Doors open today
14. Early access is live, before everyone else
15. Your private Black Friday link is inside
16. Skip the rush: shop our sale a day early
17. Members get 10% extra off from today
18. Early access ends at midnight tonight
19. Just for you: first pick of the Black Friday deals
20. Join the VIP list, get Black Friday on Wednesday
21. Your early-access code: VIP25
22. Thanksgiving treat: our sale is open already

Black Friday launch and doorbuster subject lines

Launch-day subject lines should state the headline discount immediately, because on 27 November your email competes with dozens of others in the same inbox.

23. Black Friday is ON: 30% off everything
24. It's here: up to 50% off sitewide
25. Doorbuster: the bestselling kettle, now $39
26. Black Friday deals are live. Start here
27. Today only: buy one, get one 50% off
28. 40% off boots, today only
29. Our biggest discount of 2026 starts now
30. Doorbusters until 10am: first come, first served
31. Black Friday: 25% off + free shipping
32. The deals you waited for are here
33. Black Friday prices on your favourites
34. Hourly deals all day. Here's the first one
35. Selling fast: our top 5 Black Friday deals
36. Only 200 left at this price
37. Back in stock for Black Friday, and 30% off

Free shipping, gift and weekend reminder subject lines

Weekend subject lines on 28–29 November work best when they add something new (free shipping, a gift, a new category) rather than repeating Friday's email.

38. Free shipping on everything this weekend
39. A free gift with every order over $75
40. Still deciding? Our deals run all weekend
41. New deals added for Saturday
42. Weekend bonus: an extra 10% off sale items
43. Gift-ready: our best deals under $30
44. Free returns until 31 January on Black Friday orders
45. Your cart is waiting, and so is 30% off

The subject line that gets opened is usually the one that fits the reader. Send your VIP subject lines to past buyers and your teaser lines to newer subscribers with Mailpro™ email segmentation.

Last chance subject lines

Last chance subject lines should give an exact end time, because "ends soon" is vague and "ends tonight at 11:59pm" is a decision. Pair them with a countdown timer in the email to make the deadline visible.

46. Last chance: 30% off ends at midnight
47. Final hours of Black Friday
48. Ends tonight: your Black Friday code expires
49. 3 hours left to save 40%
50. Going, going… Black Friday ends today
51. Last call for doorbuster prices
52. This is it: our sale closes at 11:59pm
53. Your discount code expires in 6 hours
54. One last look before prices go back up
55. Final reminder: free shipping ends tonight
56. Don't miss it: last day of the sale
57. We're closing the sale. Last chance to save

Cyber Monday subject lines

Cyber Monday subject lines need a new reason to open (an online-only offer, a new code, a different category), because the reader has already seen your Black Friday discount.

58. Cyber Monday: 35% off, online only
59. Missed Black Friday? Cyber Monday is your second chance
60. New code for Cyber Monday: CYBER30
61. Cyber Monday deals are live
62. Today only: Cyber Monday prices on tech
63. Cyber Monday: free express shipping
64. We saved the best for Cyber Monday
65. 24 hours of Cyber Monday deals start now
66. Cyber Monday: our lowest prices are back
67. Cyber Monday flash sale: 2pm to 6pm
68. Logging off soon: Cyber Monday ends at midnight
69. Cyber Week extended: 2 more days to save
70. Extended! Our sale now ends Tuesday 1 December
71. Cyber Week: a new deal every day until Friday

Black Friday subject lines with emojis

An emoji can help a subject line stand out in a crowded inbox, but it should support the words, not replace them, and one per subject line is enough. Test how each emoji renders in Gmail, Outlook and Apple Mail before sending.

72. 🖤 Black Friday: 30% off everything
73. ⏰ 3 hours left to save 40%
74. 🛍️ Your Black Friday picks are on sale
75. 🎁 Free gift with every order this weekend
76. 🚚 Free shipping, today only
77. ⚡ Flash sale: 2 hours, 50% off
78. 💻 Cyber Monday: tech deals live now
79. 🔒 VIP early access is open
80. 📦 Order by Sunday for delivery before 4 December
81. 🔥 Our bestsellers at Black Friday prices

B2B and SaaS Black Friday subject lines

B2B and SaaS subject lines should speak to budgets and annual plans rather than shopping excitement, because the reader is often deciding for a team and needs a business reason to act before the end of the year.

82. Black Friday: 40% off annual plans
83. Lock in 2027 pricing at Black Friday rates
84. Use your remaining 2026 budget: 30% off until Monday
85. Extra seats at half price until 30 November
86. Black Friday for teams: upgrade and save 25%
87. Our only discount of the year (it ends Monday)
88. Black Friday: double credits on every top-up
89. Annual plan, 3 months free. Ends Cyber Monday
90. Your renewal, 20% cheaper if you renew this week
91. Cyber Monday deal for agencies: 5 client accounts
92. No coupons, no gimmicks: 30% off Pro, this week
93. Black Friday webinar + offer: 1 December, 4pm

Thank-you and post-sale subject lines

Post-sale subject lines thank buyers and keep the relationship going without another discount, which protects your list from fatigue after a heavy week of sending.

94. Thank you for an amazing Black Friday
95. Your order is on its way: here's how to track it
96. How to get the most out of your new purchase
97. Missed the sale? Here's what's coming in December
98. Gift-wrapping and delivery dates for the holidays
99. We read every review. How did we do?

Mobile-short subject lines (under 25 characters)

Very short subject lines are fully visible on every phone and stand out among long, crowded ones; use them for reminders when the reader already knows the offer.

100. 30% off. Today only.
101. Ends at midnight
102. It's live
103. Last call
104. Back for 24 hours

How do you pair a subject line with a preheader?

Pair them by giving each a different job: the subject line carries the offer, the preheader carries the second detail (code, deadline, condition or proof). If the preheader repeats the subject line, you waste the second line of text the reader sees. Our article on the email preheader covers lengths and how to set it up.

Which words and habits send Black Friday emails to spam?

Spam filters react less to single words than to patterns: shouting, deception, sudden volume spikes and complaints. Black Friday multiplies all four, so check these points before 27 November:

• Shouting. ALL CAPS subject lines, "!!!", "$$$" and stacks of emojis look like spam to filters and to people.
• Classic spam phrases. "100% free", "Act now", "Risk-free", "Guaranteed", "No catch", "Click here", "You're a winner". Our list of spam words to stay away from explains why they hurt.
• Fake replies and forwards. "Re:" or "Fwd:" on a promotional email is deceptive, and readers who feel tricked report it as spam.
• Bait-and-switch offers. "70% off everything" when only a few items are 70% off. In the US, the CAN-SPAM Act prohibits misleading subject lines. In the EU, a reduced price must be compared with the lowest price of the previous 30 days (Omnibus Directive), and that applies to the price you quote in an email too.
• Complaint rate. Since 2024, Gmail and Yahoo require bulk senders to keep their spam complaint rate below 0.3% and to offer one-click unsubscribe. Here is what the 0.3% spam complaint threshold means for your sends.
• Volume spikes to cold contacts. Mailing everyone who has not opened in a year on 27 November is the fastest way to raise complaints. Send to engaged subscribers first and leave inactive contacts out.

How should you test Black Friday subject lines before 27 November?

Test subject lines on your regular emails in early November, so you know what your audience responds to before the big week. A simple A/B test compares two versions on a sample of your list and sends the winner to the rest. Useful tests for Black Friday:

• Percentage ("30% off") against amount ("$30 off").
• Emoji against no emoji.
• Deadline in the subject line against deadline in the preheader.
• "Black Friday" at the start against the offer at the start.

Need more variants to test? Here is how to use AI to write better subject lines while keeping your own voice. And if you're also planning seasonal campaigns earlier in the autumn, our Halloween subject lines follow the same stage-by-stage logic.

Frequently asked questions

When is Black Friday 2026?

Black Friday 2026 is on Friday 27 November, the day after Thanksgiving in the United States. Cyber Monday 2026 is on Monday 30 November, and many brands run a "Cyber Week" until Friday 4 December.

How long should a Black Friday subject line be?

Keep the key information within the first 30–40 characters, because that is what most phones display. The full subject line can be longer, as long as the offer or deadline comes first.

Should I put "Black Friday" in the subject line?

Yes for the launch and last chance emails, where the event itself is the reason to open. For reminders and weekend emails, the offer ("free shipping this weekend") usually says more in the same space.

How many emails should I send for Black Friday and Cyber Monday?

Most brands send between four and ten emails from mid-November to 1 December. Send more only to engaged subscribers, and give each email a new reason to open so the subject lines don't repeat.

Are emojis in Black Friday subject lines a good idea?

One relevant emoji can help a subject line stand out, especially on mobile. Use it to support the message (⏰ for a deadline, 🚚 for free shipping), never as a replacement for the offer, and test how it renders before sending.
