The Offline Channel That Drives Your Biggest Online Sales

Here's what most marketers believe: Direct mail is for driving foot traffic. Email is for driving online purchases.

That belief costs them money.

Because the data tell a different story, direct mail isn't just driving online sales. It's one of your most effective channels for getting people to click, shop, and convert online too.

Direct Mail Influences Shopping

During peak shopping season, when most purchases move online, nearly 20% of people say a direct mail piece influenced their decision to buy online (Wunderkind, 2025). That's a significant channel that companies convinced that print is dead are overlooking.

Why is direct mail so effective? Because there's something about receiving a physical piece (holding it, reading it at your own pace, without the noise of digital notifications) that creates a different kind of motivation. It gets attention in a way a crowded email inbox doesn't.

Who's Actually Responding

The surprising part isn't that direct mail works. It’s who's responding to it the most.

Gen Z, the same generation that lives on their phones, tops the list at 23% influenced by direct mail to make online purchases. Boomers come in at 18%, Millennials at 16%, and Gen X at 10%.

This contradicts the narrative that younger people don't engage with mail. Gen Z checks their mailbox daily at higher rates than Millennials (43% vs. 36%). More striking: 51% of Gen Z made an online purchase in the last six months as a direct result of having received direct mail.

Gender matters too. Men are nearly twice as likely as women to buy online after receiving a mailer (21% vs. 12%). If you're trying to reach male customers, direct mail followed by online conversion is worth serious investment.

What Gets Them to Click

Yes, discounts work. But the offers that drive online action don’t always involve price. Studies find that people often respond more strongly to the following:

• Free shipping (61%)

• Loyalty points (14%)

• Bonus gifts (13%)

• Free returns/exchanges (8%)

Sure, everyone wants a deal. But a deal doesn’t always have to be money off. In fact, these “deals” are often what your customers prefer.

The Execution Matters

A direct mail piece driving online action needs to be clear about what you want recipients to do. Don't assume they'll figure it out. Make the offer visible. Make the landing page or discount code obvious. Make it easy to act.

The piece also needs to feel valuable enough to keep. A postcard someone throws away isn't driving anyone online. A postcard with useful information, a compelling offer, and clear instructions? That stays on the counter.

Why This Matters

Most companies are splitting their budgets between offline and online channels as if they were competitors. They're not. Direct mail isn't trying to replace digital. It's actually one of your best tools for converting browsers into online buyers.

If you're not testing direct mail as part of your online conversion strategy, you're leaving money on the table, especially with younger audiences who still respond powerfully to physical mail.
