Once the sales rush is over—think Black Friday, Christmas, or end-of-season—your customers are left with full inboxes and less patience. You’ve been promoting price cuts for weeks, and now you’re transitioning back to regular pricing. So how do you keep engagement high when inbox fatigue kicks in?

Email fatigue is real. It shows up as lower open rates, more unsubscribes, and fewer clicks. But don’t worry—what you do next can make a big difference in retaining interest, trust, and loyalty.

Here’s how to beat the post-sale slump.

Know your numbers

When it comes to improving email engagement, your own data is your best guide. By now, you should have a solid grasp of how your audience behaves—when they open emails, which product recommendations drive clicks, and whether a social media nudge boosts conversions. Use those insights to shape your next move, especially when engagement starts to drop after busy sales periods.

Start by reviewing last year’s performance. Are there patterns in timing, subject lines, or content types that consistently perform well? Dig into metrics like open rates, click-throughs, and unsubscribes to understand where interest is rising—or fading. And consider adding an NPS survey to your mix. It’s a great way to get direct feedback on how customers feel about your brand—and a potential early warning sign if satisfaction is slipping.

Don’t forget the basics: tools like the Voyado Index can help you spot the best times to send, based on wider industry data. And here’s a simple, underrated trick—look at your own inbox. What grabs your attention? What do you ignore or delete? While your audience may not behave exactly like you, this exercise can give you fresh perspective on what stands out (and what doesn’t) in a crowded inbox.

📊 Quick tip: When fatigue sets in, stick to what works. Prioritize tested formats, proven send times, and content your audience already responds well to—then fine-tune from there.

Avoid routines

After a big sales push, it’s tempting to keep the momentum going with more of the same content, but your customers may not feel the same way. Repetitive messaging, especially in emails, can quickly lead to disengagement or even unsubscribe. If every message looks and sounds the same, your brand starts to fade into the background noise.

Instead, keep your communication fresh and dynamic. Swap out repetitive product pushes for value-driven content that surprises and delights. If you’ve been relying heavily on email, consider testing a well-timed SMS. If your visuals are always image-heavy, try something cleaner with a bold call to action. A little variety can go a long way.

After a busy sales period, your customers want to know they still matter to you—beyond the transaction. Tailor content to what they’ve just purchased. For example, if they bought a TV, follow up with a helpful setup guide or tips on making the most of smart features. It shows you care about their experience, not just the sale. Bonus: it’s also a great opportunity to promote relevant accessories.

Even for customers who didn’t make a purchase, there’s still room to engage. If you sell apparel or home goods, inspire your customers with content like “How to Organize Your Closet for the New Season,” subtly weaving in product recommendations.

A few ways to keep things interesting:

• Switch up channels—try SMS marketing, push notifications, or in-app messages
• Focus on post-purchase care to build long-term value
• Create helpful, seasonal content tied to your product categories

The more unexpected (yet useful) your content feels, the more likely your audience is to keep tuning in.

Segment, segment, segment

If you want to keep customers engaged, speak directly to them, not everyone at once. Highly segmented lists generate over 3x more revenue per recipient and reduce unsubscribes by 50%. That’s the power of relevance.

Segmentation lets you tailor your message based on who the customer is, what they care about, and where they are in their journey. It turns a generic message into something that feels personal, like it was made just for them.

Here are some smart ways to segment your audience:

• Purchase behavior – What they’ve bought (and how often)
• Engagement level – What emails or products they’ve clicked on
• Channel preference – In-store visitors vs. online shoppers
• Demographics – Age, life stage, and member level
• Location – Customize based on regional weather or trends
• Lifecycle stage – Are they brand new, active, or at risk of churning?

The goal? Show up with the right message at the right time—so your customers keep opening, clicking, and coming back for more.

Work on loyalty as opposed to sales

After a busy sales season, your customers are likely fatigued by discount-driven emails. Now’s the time to pivot—show them there’s more to your brand than just products. According to Retail Radar, 73% of total revenue comes from customers engaged in marketing, so make it relevant.

Focus on building connection, not conversion. Invite your audience into the process by asking for feedback on new products or letting them vote on upcoming designs. It’s a simple way to spark excitement and deepen loyalty.

Hosting an event? Tease it with countdowns, exclusive offers, and post-event content like recap videos or behind-the-scenes blog posts to keep the buzz alive. You can also highlight your loyalty program—many customers don’t realize what perks they’re already eligible for or how close they are to unlocking new ones.

Try this instead of another sales email:

• Ask customers what they’d love to see next (and let them vote!)
• Share a sneak peek or customer-designed product
• Send a “Did you know?” email about your loyalty program

Your brand is more than what you sell—make sure your customers feel that too.

Launch a win-back campaign

With the amount of marketing sent out each day, it’s no wonder that some of your contacts will lose interest in your emails. This is inevitable, but it doesn’t mean you have to let them go without making one final attempt to get them back. A re-engagement campaign involves segmenting your contacts who haven’t opened your emails in a while and sending them a special message.

Create a dedicated campaign for inactive contacts:

• Subject line: “We miss you!”
  • Acknowledge that you are sorry to see them go, but give them the option in these re-engagement emails to opt out of all communications.
• Offer frequency controls (e.g. “Get fewer emails”)
  • Offer them the option to receive only one email per week or month instead. That way, it doesn’t have to be goodbye forever. It is better to have a smaller, active contact list that opens your emails than a large one with customers who don’t really want to hear from you.
• Ask for feedback: Why did they sign up? What’s missing?
  • Ask for feedback in these emails; why did they sign up in the first place and what are they missing from your communication? Even if you have lost these customers, the insights will help with future engagement level drops.
