B2B Postcard Design: Front, Back, Size and CTA
A postcard has about three seconds to earn a second look. The front must make one point about the recipient. The back must give one reason and one action. Size, paper and the QR code support those jobs.
What makes a good B2B postcard?
A good B2B postcard makes one point about the recipient on the front, explains why it matters on the back, and gives one clear action with a reason to take it now. It looks professional but not like an ad, and it carries a unique QR code to a personal page.

What goes on the front and the back?
| Front | Back |
|---|---|
| A headline about their situation | A short note: why you are writing, in two or three sentences |
| An image that fits their industry or company | One call to action with a reason: ‘Scan for your route plan’ |
| Your logo, small | The QR code, large enough to scan easily |
| No dense text | Address block and postage, per postal rules |

Which postcard size should you use?
Larger cards stand out and hold more message, but cost more to print and mail. For cold B2B outreach, a 6 × 9 inch card is a common balance. Smaller cards suit warm, high-volume touches; larger ones suit high-value accounts. Postal rules set what counts as a postcard and how it is priced, so check before designing. Yotru’s guide to postcard sizes compares its four formats.
How should the call to action work?
One action, one reason, one place to go. ‘Scan for your 15-minute route plan’ beats ‘Visit our website, call us or follow us’. The QR code should go to a page made for that person, which repeats the card’s promise and offers a simple next step, such as booking a time. The page should load fast on a phone. Landing-page detail is in the SaaS conversion funnel, and tracking in how to track direct mail.
One card, one point, one action.
Every extra message on a postcard competes with the one that matters.
Design checklist
- Headline about them, readable from arm’s length.
- One image that fits their world.
- A note of two or three sentences on the back.
- One call to action with a reason to act now.
- A unique QR code with a short URL as a backup.
- Address and postage areas that meet postal rules.
- A proof checked on paper, not just on screen.
What to vary per card is in personalized direct mail; what to expect from it in direct mail response rates.
