How it works
Encode a mailto link so scanning opens the phone's mail app with your address, a subject line, and even a message body prepared. Handy for support notices, feedback requests, and equipment labels where you want context attached to whatever people send.
- 1Enter the address that should receive the mail.
- 2Add a subject line — a specific one makes triage much easier later.
- 3Optionally prefill the body with the details you always end up asking for.
- 4Generate, download, and print.
Frequently asked questions
- What is a mailto QR code?
- A QR code containing a mailto link. Scanning it opens a new draft in the phone's mail app with the address, subject, and body you specified.
- Can I prefill the message body?
- Yes. It is genuinely useful for support: prefill prompts like 'Order number:' and 'What went wrong:' and the replies arrive far more complete.
- Does it work with Gmail and Outlook apps?
- Yes, it opens whatever the device has set as its default mail app.
- Will this expose my address to spam bots?
- Less than publishing it as text, since crawlers do not typically decode printed QR images. But the address is recoverable by anyone who scans the code.
