What Are Plastic Postcards
& Why Do They Work?

Plastic postcard mailers and gift card mailers are a powerful way to grab attention in direct mail campaigns. These plastic postcards stand out in the mailbox with their durable, laminated design, giving your brand a premium look while delivering impressive ROI.

Add in the option of personalized variable messaging, where you can create custom, unique messaging for each recipient of your plastic postcard mailer, for a huge response rate.

They work because they:

  • Feel valuable in hand, like a real gift card

  • Stand out from other mail with glossy, heavy-duty stock

  • Drive in-store visits and quick redemption

  • Deliver higher direct mail response rates than standard formats

Paired with variable data personalization, these plastic postcard mailers can generate up to 900% ROI when deployed strategically.
