Black Friday and Cyber Monday (BFCM) account for a huge chunk of annual revenue for most online stores. Some stores do 20-30% of their yearly sales in this single weekend. Email is the #1 channel for driving that revenue, beating paid ads and social media consistently.

But here's the thing: every other store is also blasting emails during BFCM. Your customers' inboxes are flooded. If you want your campaigns to stand out, you need to plan ahead and be strategic about what you send.

This guide covers the full timeline, from planning months out to following up after the sale ends.

The BFCM Email Timeline

2-3 Months Before: Foundation

Clean your email list. This is critical. Remove or suppress subscribers who haven't opened an email in 6+ months. Sending to a clean list during BFCM means better deliverability when it matters most.

Warm up your sending volume. If you normally send 2 emails per week, don't suddenly send 5 per day during BFCM. Gradually increase your sending frequency over the weeks leading up to it. Email providers notice sudden spikes and may throttle or spam-filter your campaigns.

Plan your offers. Decide what you're actually going to discount and by how much. Don't figure this out the week before. Consider:

Site-wide percentage off (simple, easy to communicate)
Category-specific deals
Bundle deals
Free shipping thresholds
Gift with purchase
Early access for VIPs

Build your segments. At minimum, you should have:

VIP customers (top 10-20% by spend)
Active customers (purchased in last 90 days)
Lapsed customers (haven't purchased in 90+ days)
Subscribers who've never purchased
Email-engaged vs. disengaged

3-4 Weeks Before: Tease and Build Anticipation

Send a "BFCM is coming" email. Let people know you'll have deals. Don't reveal specifics yet. Create anticipation.

Collect preferences. Send a quick survey or preference center update. "What categories interest you most?" This helps you send more relevant offers during the actual sale.

VIP early access announcement. Tell your best customers they'll get first dibs. This makes them feel special and gives you a reason to email them before the main event.

Grow your list. Run a "sign up for early access to our Black Friday deals" campaign. People who specifically sign up for BFCM are highly motivated buyers.

1 Week Before: Build Urgency

Preview email. Give a sneak peek of what's coming. "Here's what you can expect this Black Friday." Include a few highlights without revealing everything.

Calendar reminder. "Save the date: our biggest sale starts [day] at [time]." Make it easy for people to plan.

VIP early access starts. If you're doing early access, launch it 24-48 hours before the main event. This also stress-tests your systems before peak traffic.

Black Friday Weekend: Execute

This is where most of the revenue happens. Here's a typical send schedule:

Thursday evening (Thanksgiving in the US):

Preview/teaser for midnight launch
Only send to your most engaged segment

Friday morning (Black Friday launch):

Main announcement to full list
Clear offer, clear deadline, clear CTA
Keep the email simple. People are scanning, not reading.

Friday evening:

"In case you missed it" to non-openers
Highlight best-selling items or items selling fast

Saturday:

Mid-sale content. Customer favorites, gift guides, or staff picks.
Social proof: "1,000 orders shipped today" or similar

Sunday:

"Last day before Cyber Monday" or transition messaging
Highlight different deals if you're changing offers

Monday (Cyber Monday):

Morning launch for Cyber Monday specific deals
Afternoon: urgency push. "Deals end at midnight."
Evening: final hours reminder to engaged segments only

Tuesday (Extended sale, if running one):

"We extended our sale for 24 more hours" (use this sparingly, not every year)

After BFCM: Follow Up

Thank you email (within 24 hours of sale ending):

Genuine gratitude. "We just had our biggest sale ever. Thank you."
Don't sell anything in this email.

Shipping update (as orders ship):

Keep customers informed, especially during high-volume periods when shipping may be slower

Post-purchase sequence:

Your regular post-purchase flow should kick in for all BFCM orders
Adjust timing if shipping is delayed

Win-back the non-buyers (1 week after):

"Missed our Black Friday sale? Here's a small thank-you for being on our list."
A much smaller offer, or just great content

Tips That Actually Make a Difference

Subject lines matter more during BFCM. Everyone is competing for attention. Test your subject lines ahead of time. Specificity beats generic: "40% off all jackets" beats "Our biggest sale ever!" Include the discount number or specific benefit.

Send time optimization helps. If your email platform supports it, let it pick the best time for each subscriber based on when they usually open emails. Sequenzy's send time optimization does this automatically.

Don't be afraid to send more emails. During BFCM specifically, people expect more emails. 2-3 per day is normal and acceptable for this weekend. But only if you've warmed up your sending volume in the weeks before.

Mobile first, always. Over 60% of BFCM emails are opened on mobile. Big buttons, clear CTAs, product images that look good on small screens.

Resend to non-openers. Your Friday morning email will have non-openers. Resend it Friday evening with a different subject line. You'll pick up another 10-20% of opens.

Have a Plan B for your website. If your site crashes from traffic, have an email ready that offers an alternative (extend the sale, offer a rain check, direct to specific product pages instead of the homepage).

Segmented BFCM Strategy

Don't send the same email to everyone. Here's how to differentiate:

VIPs: Early access + better offers. They've earned it. "As one of our top customers, you get first access and an extra 10% on top of our sale."

Active customers: Standard offers with personalized product recommendations based on past purchases.

Lapsed customers: Frame it as a reason to come back. "It's been a while. Our biggest sale of the year is the perfect time to check back in."

Never-purchased subscribers: Remove friction. Free shipping, easy returns, money-back guarantee. They need trust signals more than discounts.

Engaged vs. disengaged: Send the full sequence to engaged subscribers. For disengaged ones, send just the main announcement. If they don't engage with BFCM emails, they probably won't engage with anything.

BFCM Mistakes to Avoid

Starting too late. If you're planning your BFCM email strategy in November, you're already behind. Start in September or October at the latest.

Not warming up sending volume. Going from 2 emails/week to 3/day will trigger spam filters. Ramp up gradually.

Discounting everything. Not everything needs to be on sale. Strategic discounting on key products often works better than a blanket "everything is X% off."

Ignoring post-BFCM. Many stores acquire a ton of new customers during BFCM who never come back. Your post-purchase sequence determines whether they become repeat buyers or one-time bargain hunters.

Sending to your entire list without segmenting. Your VIPs should get a different experience than someone who just signed up yesterday.

Forgetting about deliverability. Clean your list before BFCM. A dirty list during the highest-volume sending period of the year is a recipe for landing in spam.

Getting Started

If BFCM is still months away, here's what to do now:

Clean your email list
Start building your segments (VIP, active, lapsed, never-purchased)
Plan your offer structure
Create a rough email calendar for the BFCM week
Set up your post-purchase sequence if you don't have one (read our post-purchase guide)

If BFCM is right around the corner and you're reading this in a panic, focus on three things: clean your list, plan your offer, and write your Friday morning email. Those three things will cover 80% of the impact.
