Sending Handwritten Thank-You Notes to Customers (At Scale!)

Mar 21, 2025

If you’re here and looking for a solution that can help you send handwritten thank-you notes for customers at scale, you don’t actually have to read this article. Check out our handwritten cards page for quick info and a link to chat with us. We have high-tech handwritten robots (see later in this piece)!

But if you want to read more about why we (super cool direct mail company called PostPilot) love handwritten cards, keep on scrolling.

Basically, handwritten thank-you notes for customers represent the best of direct mail.

Direct mail is already a fundamentally more personal channel (in that you’re literally getting messages into your customers’ hands), but when you send handwritten notes, it’s a next-next level way of connecting with your customers.

Oh, and driving crazy ROI.

Handwritten Cards Slice Through the Noise

Emails, texts, ads, notifications—they're literally everywhere.

And your customers tune out 95% of them. But handwritten thank-you notes? They're practically guaranteed to get noticed. No spam filters, no "promotions" tab in mailboxes, either—just your heartfelt thanks, right in your customer's hands.

Think about it: direct mail in general stands out, but a handwritten card from a brand?

That's unusual.

In the best possible way.

In fact, people actually look forward to checking their mailboxes. An unexpected handwritten note doesn't get ignored—it gets pinned to the fridge.

Unless it’s like, from State Farm, and the “handwritten” cards are handwritten by printers at a factory in Omaha.

(We don’t actually know if the factory is in Omaha, but they are done by printers.)

Customers Feel the Love

A handwritten note tells your customers one thing loud and clear: you genuinely care.

No automated email template or chatbot can match that personal, human connection. And ecommerce brands thrive when customers feel valued.

Case in point: the apparel brand &Collar used PostPilot to send handwritten thank-you notes to thousands of their top customers.

No discount codes, no upsell—just a simple, sincere "thank you."

The response? Over $200,000 in extra revenue and a 15x+ ROI, purely from customers who appreciated being appreciated.

Also, the fact that &Collar’s CEO, Ben Perkins, used his actual email address in there is a baller move.

Big-Time Loyalty at a Low Cost

A line you’ve heard a hundred billion times: it costs way more to acquire new customers than keep existing ones.

But most brands still neglect retention. Handwritten notes are a genuinely high-impact tactic for driving repurchases...for half the price of a latte ($1.99).

Brands like nbt use PostPilot to send not just thank-you notes, but welcomes to their loyalty programs (plus a generous discount to drive more sales from these super valuable customers).

And it works.

When customers feel genuinely valued, they stick around.

They choose you again because you've treated them differently (and better) than the dozens of other brands competing for their dollars.

Emails are, of course, fundamental and obligatory for any marketing program. But you can’t hold an email and smudge the (real) handwritten ink.

Automating the Human Touch (Really!)

The biggest objection we hear from ecommerce owners is, "Sure, sounds great—but I can't write hundreds of cards myself." You don't have to. PostPilot uses real pens, real ink, and real stamps to automate handwritten thank-you notes at scale. Yes, robots write them—but your customers won't know the difference.

Ben from &Collar admitted he was skeptical at first. But after seeing PostPilot’s cards, he said, "They look incredibly real."

Real enough to pass the fridge test and real enough to generate substantial sales. Win-win. And probably an extra win or two.

Ditch Generic, Go Personal. Send Handwritten Thank-You Notes to Your Customers.

If you want loyalty, higher retention, and happy customers singing your praises, handwritten thank-you notes are a smart, scalable, and affordable way to get there.
