The QR Code for a coupon in an email must be large enough to for a scanner to discern the pattern.
After creating a campaign and sending a test email (recommended), you can test with your QR code scanner or a smartphone with the Camera or QR Scanner app.
- The code should be at least 115 x 115 pixels(px), or 1 x 1 inches(in) wide.
- The QR code should be padded with at least 1 pixel on all sides to create a clear border from the edge of the code, to ensure scanability.
- After making a test campaign to send to yourself with a live code, test it with the QR scanner to ensure that it works with no errors and pulls the right discount.
