How Direct Mailing Helps E-Commerce Brands Stand Out—And Drive More Revenue
PostPilot works with dozens of agencies, but when they wanted to spotlight what direct mail can really do inside Klaviyo, they chose ECD for a full case study.
Their whole team promoted the post online, and once you see the results, you’ll understand why.
Our strategies have generated 5x, 10x, and even 15x returns for e-commerce brands.
This blog breaks down what makes direct mail work, the plays we use most, and how you can integrate it into a scalable retention system.
Why Direct Mail for E-commerce Works (When Emails Don’t)
During Black Friday and other peak sales windows, inboxes are chaos.
Direct mail doesn’t have to compete. Fewer e-commerce brands send it, so it shows up with less distraction.
And because each postcard is tied to a specific customer action, it doesn’t feel like a campaign blast. It feels personal. Intentional. Like a 1:1 nudge timed to exactly where they are in their journey.
We’ve seen it outperform email, not because the offer changes, but because the delivery feels different.
Where Marketing Postcards Fit in the Funnel
At ECD, we build postcards into the same lifecycle flows you’re already running in Klaviyo. It’s a winback that hits the inbox and the mailbox. A cart abandonment email backed up with a physical reminder. A seasonal campaign that shows up even if they missed the subject line.
5 Direct Mail Plays That Consistently Convert
At ECD, we build postcards into the same lifecycle flows you’re already running in Klaviyo. Think: a winback that hits the inbox and the mailbox. A cart abandonment email backed up with a physical reminder. A seasonal campaign that shows up even if they missed the subject line.
WINBACKS WITH A DEADLINE
Send to lapsed buyers with a tight offer window (e.g., “20% off this weekend only”). That combination of timing and format works: the message stands alone, the urgency is clear, and the physical reminder is hard to ignore.
AUTOMATED BIRTHDAY CARDS
Personalized + timely = powerful. A birthday postcard with a thank you or gift incentive performs well across categories and builds goodwill that makes customers want to come back.
POSTCARD FALLSBACK IN ABANDONMENT FLOWS
If your cart or browse flow hasn’t converted after 7–10 days, don’t just resend the same email. Drop a postcard. It gives the offer a second chance to land—and shows up in a different context.
HIGH-INTENT CROSS-SELLS
If someone bought once, mail them a complementary product 30–90 days later. Postcards are perfect for this: product-focused, non-intrusive, and often more engaging than a third “just checking in” email.
VIP NUDGES
Want to turn a 2-time customer into a 5-time one? Acknowledge them. Then incentivize them. Use direct mail to thank them, surprise them with a gift, or invite them into something exclusive. It doesn’t just drive repeat purchases—it builds loyalty in a way digital rarely does.
The best part? Most campaigns don’t require manual sends.
Some sends still require manual setup, but it’s minimal. Most are built inside your Klaviyo flows and triggered automatically. That means direct mail becomes part of your existing lifecycle system, just like email and SMS.
