How does an email QR code work?
The code encodes a standard mailto: link containing your email address and, optionally, a pre-written subject and body. When someone scans it, their default email app opens a new message with those fields already filled in. They simply review and hit send.
Can I pre-fill the subject and body?
Yes. Add an optional subject line and message body when you generate the code. Both are encoded into the mailto: link, so the recipient sees a ready-to-send draft. This is ideal for feedback forms, support requests, RSVPs, and standardized enquiries.
Which email apps does it work with?
Email QR codes use the universal mailto: standard, which is supported by virtually every email client. Gmail, Apple Mail, Outlook, Yahoo, and more. On iOS, Android, and desktop. The message opens in whichever app the person has set as their default.
Do people need a special app to scan it?
No. Modern iPhones and most Android phones read QR codes directly from the built-in camera app. The user opens the camera, points it at the code, and taps the prompt that appears to open their email app.
Does a scan guarantee an email is sent?
No. Scanning opens a pre-filled draft, but the person still has to press send. Some may scan out of curiosity and close the app. Think of it as removing friction from the process rather than a guaranteed submission.
Can I customize the colors of the email QR code?
Yes. After generating, use the customization panel to change the foreground and background colors or set a transparent background so the code fits your branded materials. Always scan-test a customized code before printing to confirm it still reads reliably.
Where should I place an email QR code?
Anywhere you invite a written response: feedback cards, event invitations, product packaging, business cards, posters, receipts, and email signatures. It works especially well when you want a structured message with a consistent subject line.
