Custom Thank You Cards: The $0.08 Insert That Drives Repeat Sales

A custom thank you card costs $0.08 and increases repeat purchase rates by 20-25%%. At that ROI, every order you ship without one is leaving money on the table.

This guide covers design best practices, printing options, and conversion tactics from Cubit's custom thank you card program.

The Three-Element Formula

The most effective thank you cards combine three elements: (1) a genuine thank you message that makes the customer feel valued, (2) a clear call-to-action (leave a review, follow on social, use a discount code), and (3) a QR code that takes them directly to the action page.

Cards with QR codes see 3x more engagement than text-only cards. The QR code eliminates friction — customers scan instead of typing a URL.

What to Print on Each Side

Front: Your brand name, a genuine thank you message, and a visual that matches your brand aesthetic. Keep it beautiful enough that customers photograph it.

Back: QR code linking to your review page, a discount code for next purchase (THANKYOU15 works well), your social media handles, and optionally product care instructions or a brand story snippet.

Advanced Tactics

Scratch-Off Panels: Silver scratch-off coating hiding a discount code or surprise. Gamifies the unboxing and increases engagement by 2-3x over standard printed codes.

Variable Data: Digital printing supports unique discount codes per card for tracking redemption rates by cohort.

Pair with custom tissue paper and custom stickers for a complete branded unboxing kit.
