The 10 Must-Know Rules for Direct Mail That Works

‐ June 12, 2025

If you’re looking to get more responses—and more sales—these 10 simple rules will help boost the performance of your direct mail and other marketing efforts.

Let’s start with the basics: Why Direct Mail?

The main goal of direct mail is lead generation. That’s where it works best. It gets your message into the hands of real people—something that’s getting harder with digital marketing.

But here’s the honest truth:

Most direct mail gets opened over the trash can. You have about 2 seconds to grab someone’s attention before your postcard is tossed. That’s not good or bad—it’s just how it is. So, your piece needs to pop immediately.

Here are 10 rules to follow when working with one of our designers or creating your next postcard:

1. Use a Bold, Clear Headline

Your headline is everything. It’s the first thing people see—and it has to hook them.

A great headline shares a clear benefit and takes up at least 15% of the front of the card. Keep it clean, uncluttered, and straight to the point.

2. Include a Graphic That Matches Your Message

Images should reinforce your message.

For example, selling real estate? A picture of a house with a big “SOLD” sign hits harder than just a plain house photo. Make the visual work with the headline.

3. Use Color That Pops

Make sure your headline and key text stand out from the background.

When you look at your card, ask:

“What catches my eye first?”

If it’s not the headline, rethink the color contrast.

4. Add Subheads That Guide the Reader

People skim. Subheads help guide their eyes and let them pick up the key benefits fast.

Avoid long blocks of text. Less is more. Your goal is to get them interested enough to call—not to tell the whole story.

5. Sell Benefits, Not Features

This is a big one. Don’t assume people understand how a “lower interest rate” helps them.

Instead, say something like:

“Lower your monthly mortgage payment by $250.”

That’s a benefit they can feel.

6. Make an Offer They Can’t Ignore

Give people a reason to act right now.

Examples:

  • “Limited spots available”
  • “Interest rates are climbing”
  • “Offer ends Friday”

Urgency + value = response.

7. Include Your Company Name & Logo—But Don’t Lead With It

Yes, your branding matters. But your logo shouldn’t be the star.

Put the offer and benefits front and center. People care most about what’s in it for them.

8. Have a Strong Call to Action

Tell them exactly what to do next.

Examples:

  • “Call now for a free quote”
  • “Visit us online today” Make it clear and easy.

9. Add Your Contact Info

Right after your call to action, include your name, phone number, and website.

Whatever action you want them to take, make sure the path is simple and obvious.

10. Don’t Forget the Return Address

A return address isn’t just for mail that comes back—it makes you look more legit.

It shows your business is real and grounded, which builds trust.

Staying Consistent Is What Wins

This list isn’t everything, but it’s a strong start. Good design, smart layout, and clear messaging all help too.

There’s no single marketing trick that works every time. But if you stay consistent, test what works, and keep your message focused on the customer, direct mail can be one of your most powerful tools. It’s stuck around this long for a reason—it gets results.
