What is a Gmail QR code and how does it work?
A Gmail QR code created with this editor opens a Gmail compose link containing a recipient and optional subject and body. The recipient can use a Gmail or another email address; the link chooses Gmail as the composing service. The reader needs access to Gmail and reviews the message before sending. Opening in an app or browser and retaining draft fields depend on the device and session, so test the complete flow.
For a support card, use a subject such as Product care question and a short prompt asking which product needs help. Add your logo and colours with custom QR designs. The reader checks the draft and sends it through Gmail, as explained in Google’s message-sending guide. Test with the Gmail accounts and devices your audience uses before printing.
