7 Examples of Personalized Direct Mail (That Actually Drive Sales!)

Most generic postcards get trashed before they’re ever read.

But when a brand takes the time to make a mailer feel relevant and personal, it earns attention.

And more importantly, action. Y’know. Purchases.

Yet direct mail remains a wildly underutilized channel, despite its ability to scale revenue well into 8 figures.

The brands doing it right are seeing major returns, and doing it right starts with personalization.

Here are seven real-world examples of ecomm brands using personalized direct mail to re-engage customers, drive conversions, and generate serious revenue (at high ROIs!).

1. The Beard Struggle: Automating Winbacks and VIP Loyalty

What they did:
The Beard Struggle (TBS) implemented a direct mail program and automated postcards to address digital saturation and improve customer retention.

How they did it:
They sent programmatically triggered postcards based on buying behavior, including 90-, 270-, and 520-day winback intervals. Additionally, they targeted VIP customers with exclusive offers to join their Brand Vikings™ loyalty program.

Why it worked:
By reaching customers at key moments in their lifecycle with personalized messages, TBS effectively re-engaged lapsed customers and strengthened loyalty among their top spenders.

Results:
TBS achieved a MINIMUM of 6x ROAS across all campaigns.

2. Wine by Lamborghini: High-Touch Retention for Luxury Buyers

What they did:
Faced with rising acquisition costs and limited email reach, Wine by Lamborghini turned to direct mail to enhance customer retention.

How they did it:
They used PostPilot's MailMatch to identify physical addresses from email lists, sending personalized direct mail with a 25% discount to two segments: email subscribers who hadn't purchased within 30 days and those who had unsubscribed.

Why it worked:
Luxury consumers appreciate tangible, high-quality communications. The postcards stood out in the mailbox, offering a tactile reminder of the brand's exclusivity.

Results:
The campaign achieved a a 10x ROAS. Who could resist a postcard (and product) that looks like THAT?

3. Plum Deluxe: Scaling Handwritten Birthday Wishes

What they did:
Plum Deluxe sought to maintain their tradition of sending birthday cards to Tea Club members and Facebook community participants.

How they did it:
Partnering with PostPilot, they automated the sending of personalized, handwritten-style birthday cards, even identifying birthdays for customers without previously collected data using PostPilot's massive proprietary data set.

Why it worked:
The personal touch of a birthday card fostered a deeper emotional connection, enhancing customer loyalty and engagement. And it looks like real writing! But it's done by handwriting robots! Ahhhhh!

Results:
The birthday campaign yielded an average ROAS of 9.6x and an extraordinary (but accurate) conversion rate of 28.5%.

4. Mini Katana: Re-Engaging Lapsed Customers

What they did:
Mini Katana aimed to re-engage customers who had made three purchases but hadn't bought anything in the past three to six months.

How they did it:
Using PostPilot, they sent winback postcards to these customers. Additionally, they employed MailMatch^TM to identify and send postcards to email subscribers who hadn't converted.

Why it worked:
The physical postcards served as a tangible reminder, SLICING through digital noise and prompting re-engagement.

Results:
The winback campaign achieved a 9x ROAS, while the MailMatch campaign yielded a 5x ROAS.

5. Caddis: Dynamic Retargeting and Retention

What they did:
Caddis sought to drive new and repeat revenue through a wide array of direct mail tactics.

How they did it:
They dynamically retargeted and converted anonymous site visitors and cart abandoners, and re-engaged one-time customers and those with specific buying behaviors using PostPilot's SiteMatch^TM and MailMatch features.

Why it worked:
By addressing different customer segments with tailored messages, Caddis effectively moved customers through the purchase funnel.

Results:
Their automated abandoned cart retargeting campaign achieved an unbelievable (but again, accurate) 15.3x INCREMENTAL ROAS.

6. Grande Cosmetics: Re-Engaging VIP Customers

What they did:
Grande Cosmetics aimed to re-engage valuable shoppers at exactly the right time, entice first-time purchasers, and cross-sell slower-moving SKUs.

“We're hitting them just at that point where they're probably due for a refill of their product,” Christie Porter, (Grande Cosmetics’ director of ecommerce) told us.

How they did it:
Integrating PostPilot with Shopify and Klaviyo, they sent postcards to customers who hadn't made a purchase in at least three months, offering a limited-time 20% discount.

Why it worked:
The timely, tangible, intensely vibrant reminder stood out amid digital clutter, prompting customers to restock their favorite products.

Results:
Across three initial winback campaigns, they generated $96,000 in sales from the coupon codes alone.

7. HexClad: Converting Email Subscribers with Direct Mail

What they did:
HexClad targeted email subscribers who hadn't yet made a purchase, especially during the BFCM period.

To boost LTV, the team sent postcards to dormant VIPs, including those unengaged with email/SMS. Although those unsubscribed VIPs weren’t reachable via owned channels, HexClad connected with them at home using first-party purchase data.

How they did it:
Using PostPilot's MailMatch, they identified physical addresses from email lists and sent sleek, eye-catching postcards featuring product benefits and compelling offers.

Why it worked:
The physical postcards served as a memorable touchpoint, nudging subscribers to convert during a high-intent shopping period.
