What is an Email QR Code?
An email QR code encodes mailto:[email protected]?subject=Inquiry&body=Hello. Scanning opens the mail app with recipient, subject and body pre-filled. On a B2B trade-show card it beats a printed address every time.
Encoding structure
- Format:
mailto:address?subject=…&body=…; - Special characters (spaces, Chinese, &) are URL-encoded automatically by CodeBox;
- Bodies can contain newlines; keep ≤ ~200 characters to avoid a large code.
How to generate an email QR code
- Fill in the recipient address, subject and body;
- Confirm the encoded link in the preview;
- For business cards, use error correction M;
- Download PNG/SVG.
Typical uses
- Trade-show cards: one scan to email a quote request;
- Equipment nameplates: pre-filled repair report;
- Recruiting posters: scan to apply (job title pre-filled).
