Black Friday is around the corner. Most brands are heads-down on discounts, creative, and campaign calendars… but here’s the truth: the biggest driver of success isn’t your offer. It’s the size and quality of your email list.

At Aimerce, we’ve seen this pattern across 1,000+ Shopify and Klaviyo installs: the brands that WIN Black Friday don’t start in November. They start months earlier, when subscriber costs are cheaper and inboxes are quieter.

Black Friday = Make-or-Break

In 2024, Black Friday alone hit $10.8B in U.S. sales; Cyber Week drove $41.1B. For many brands, nearly 20% of yearly revenue rides on this one week. But competition gets brutal: Meta CPCs spike to $0.90, Google clicks to $4.66, and CPMs up 66%. At the same time, 365M+ emails flood inboxes.

Why Your Email List is the Edge

Email is owned media. You’re not renting attention from Meta or Google, and you’re talking directly to your customers. We’ve seen acquisition costs at $1–3 per subscriber vs. $30–50 on ads. ROI? $36 to 42 per $1 spent, and even higher with flows like abandoned cart and post-purchase.

8 Ways to Accelerate Growth Before November

• ✅ Refresh popups & checkout capture (15–25% more emails)
• ✅ Turn social followers into subscribers with lead ads & bio links
• ✅ Cross-pollinate channels: email <> social
• ✅ Run giveaways with partners, attract the RIGHT customers
• ✅ Create lead magnets (gift guides, seasonal content, exclusive drops)
• ✅ Collaborate with complementary brands
• ✅ Optimize every touchpoint (post-purchase, packaging inserts, support teams)
• ✅ Build referral & loyalty loops to compound growth

The Bottom Line

While competitors scramble (and overspend) in late November, you could be emailing an audience you’ve nurtured all fall, but at a fraction of the cost. Your Black Friday success story starts with the list-building work you do today.

So… the real question is: can you afford NOT to grow your list now?
