Black Friday is over. Now what?

For most brands, December is a quiet victory lap, a “we’ve done enough” month. But that’s the biggest mistake you can make.

Because right after BFCM, when many brands go silent, your customers are still expectant.

They just bought from you. They’re checking their emails. They’re scrolling. They’re ready. But if you disappear for two weeks, they forget you by January. So, stop treating December like your cooldown period; it’s your retention window.

This is the month that decides whether your new customers become one-time buyers or lifetime ambassadors.

Here’s what you should do in December:

• Run a “Thank You” Campaign: Show gratitude. Send a simple “we appreciate you” message, and consider including a small gift or offering early access to your January drop. It’s a form of emotional ROI.

• Turn BFCM Data into Strategy: Analyze who bought what. Segment your new customers into buckets: repeat buyers, first-timers, and high AOV. Then, create personalized post-purchase journeys before the end of the year.

• Send Post-Purchase Content, Not Discounts: Your December emails should focus on building trust. Send emails like: “How to get the most out of your product,” “What’s coming next”, “Real stories from people just like you.”

• Reinvest in Experience: Fix every friction point your BFCM rush exposed, slow pages, broken checkouts, and delayed shipping. Operational wins now pay off big in Q1.
