  • Sales enquiries on brochures and product sheets.
  • Event registration and contact points.

FAQ

What happens when someone scans the code?

Their mail app opens a draft with your address, subject and message already filled in. Nothing is sent until the person reviews the draft and taps send themselves.

Can I prefill the subject and the message?

Yes, both fields are optional. Keep them short: they are stored inside the code, and a long body makes the pattern noticeably denser.

Which mail apps does it work with?

Any app registered for mailto links — Gmail, Outlook, Apple Mail and the rest. If the phone has no mail app configured, the system asks the user to pick one.

Email QR code behaviour, prefilled drafts and limits

Capacity and limits

The address, subject and body all travel inside the code, and the subject and body are percent-encoded, which makes spaces and punctuation cost more than their plain length suggests. A one-line subject is cheap; a full paragraph in the body noticeably densifies the pattern.

Device compatibility

Anything that handles mailto links opens the draft: Gmail, Outlook, Apple Mail and the rest. If no mail app is configured, the phone asks the person to pick one, and on desktop the browser may prompt for a default handler. Nothing is ever sent automatically.

Common mistakes

  • Writing the whole message into the body — people edit prefilled drafts anyway, and the density cost is paid on every print run.
  • Using an address that forwards to a shared inbox without checking that replies come back from the same address.
  • Assuming the subject line survives every client identically; treat it as a helpful default, not a guarantee.

Printing and placement

Email codes usually sit on brochures, stands and receipts that are read from arm's length, so 25 to 30 mm is normally enough. Keep the code away from the fold on a folded leaflet, where scanners struggle with the curve.
