You can add custom inserts to your on-demand product orders to give every shipment a more personal and premium touch. Inserts are printed on-demand on premium matte card stock and can be used for a variety of purposes, such as thank-you notes, personal messages, or branded cards.
How does it work?
Once you have set up custom inserts, orders that contain at least one supported product will have the custom insert added in the packaging. This gives it a more premium and unique touch to those orders. For each insert, you will be charged $0.25 on orders where inserts are supported and you will see this in that order's cost breakdown.
Note: Only one custom insert is added per order.
Art file requirements
Your insert design should meet the following specifications:
- Size: 6 × 4 inches (15.24 × 10.16 cm)
- Resolution: 1,800 × 1,200 px at 300 DPI
- File type: PNG or JPEG
Setting up custom inserts
To start, go to Settings > Custom inserts
Turn on the “Add custom insert” toggle (the switch will turn blue when enabled) to activate custom inserts.
Next, upload the image you want to print in the custom insert by clicking "Upload image" and then "Confirm".
Once uploaded, you’ll see a preview of your insert and a toggle showing it’s active. (see image below). Click Save to finish.
Note: There is a small 3/8" white border around the edge of the card. You will see it in the design preview.

Creative Ways to Use Custom Inserts
Custom inserts aren’t just for thank-you notes, they’re a great way to connect with supporters, promote new content, or boost repeat orders. Here are some creative ways to use them:
Upsell Memberships - Include a “Members-Only” invite card with a QR code that links to perks, early access, or a free trial.
Podcaster Sponsorships - Turn your insert into a mini “ad read” featuring your current sponsor. Add a QR code linking to their offer or exclusive content.
Interactive Thank-You Cards - Add a handwritten or printed signature, or include a QR code that leads to a short thank-you video. You can also share the story of how each purchase supports you or your work.
Promo Codes & Auto Discounts - Use a QR code that automatically applies a discount at checkout for the next purchase. You can update codes over time to align with new campaigns.
Early Access or Secret Drops - Add a password or QR code that unlocks a hidden product page or exclusive collection. It creates a “Vault Access” or “Backstage Pass” feel for supporters.
Seasonal or Collectible Inserts - Create themed or numbered cards (e.g., “1 of 4 seasonal series”) to encourage fans to collect or trade them.
Other miscellaneous ideas:
• Include a product tutorial or styling guide via QR code.
• Add a “Tag us on social” prompt to encourage user-generated content.
