What happens when someone scans an email QR code?

Their phone opens its mail app with the address, subject, and message already filled in. Nothing is sent automatically — the scanner reviews it and taps send themselves.

Can I prefill the subject and message?

Yes, both are optional fields. Prefilling them is great for feedback requests or support tickets — the scanner just adds their details and sends. You can also CC a second address.

Can the code send to more than one address?

Yes — separate several addresses with commas in the To field, and the same in CC. All of them appear in the scanner's mail app.

Is my email address stored anywhere?

Not by us. The code is generated in your browser, free with no signup. The address is encoded in the QR squares themselves, so anyone who scans it can read it — only use addresses you are happy to share.
