What this tool does
Email QR Code Generator encodes a mailto: link with a recipient address and an optional pre-filled subject and body as a QR code. Scanning it opens the device’s default email app with a new draft already addressed and filled in, ready for the sender to review and send.
Sharing an email address on a poster, business card or sign still usually means someone manually typing it, with the real risk of a typo sending the message nowhere, plus no way to pre-suggest a useful subject line or starting message.
This generator encodes a standard mailto: link, with the recipient address and an optional pre-filled subject and body, as a QR code. Scanning it opens the device’s default email app with a new draft already addressed and filled in, which the sender can review, edit and send, no manual typing of the address required.
How to use Email QR Code Generator
- Enter the To email address.
- Optionally enter a Subject that will pre-fill the new draft.
- Optionally enter a Body with starting message text.
- Download or display the generated QR code.
Tips for better results
- A pre-filled subject line is especially useful for routing, such as "Support Request" or "Event Inquiry", helping the recipient triage incoming emails faster.
- The pre-filled body is just a starting point; the sender can freely edit it before sending, so use it to suggest useful context rather than a rigid required format.
- This QR code opens whichever email app is set as default on the scanning device, which may differ from person to person; it works the same way a regular mailto: link does when clicked on a webpage.
- Keep the subject and body reasonably short; extremely long pre-filled text can behave inconsistently across different email apps and devices.
Common use cases
- Adding a "Scan to email us" QR code to a business card, poster or storefront sign.
- Routing inquiries to the right subject line automatically via a pre-filled subject.
- Including a quick-contact QR code in an event program or information booth.
- Sharing an email address reliably without risk of a manual typing error.
Common mistakes to avoid
- Entering an email address without the @ symbol or with a typo, which the generator flags before building the QR code, since it would otherwise produce a non-functional mailto: link.
- Writing an overly long or formal pre-filled body that feels more like a locked template than a helpful starting point.
- Assuming every scanning device has the same default email app configured; the experience depends on whatever app is set as default on the scanner’s own device.
Frequently asked questions
Can the recipient edit the pre-filled subject and body?
Yes, the subject and body simply pre-fill the new email draft; the sender can freely edit, add to, or clear either field before actually sending the email.
Which email app opens when this is scanned?
Whichever email app is set as the default on the scanning device, the same behaviour as clicking a regular mailto: link on a webpage.
Is the email address validated?
The generator checks for a basic valid format (containing an @ symbol) before building the QR code, though it doesn’t verify the address actually exists or can receive mail.
Can I leave the subject and body blank?
Yes, both are optional; leaving them blank produces a QR code that simply opens a new blank email addressed to the recipient.
