📖 Complete Guide: Email QR Codes for Business & Marketing
Email is still the most universally supported communication channel — more than social media, more than messaging apps. Email QR codes leverage this by encoding a mailto: link that opens any email app on any device, with your recipient address, subject and body pre-filled. Instead of asking someone to search for your email address or type it manually, they scan once and their email app opens with everything ready to send.
Understanding the mailto: URI Scheme
The mailto: URI is a standard web protocol supported by every email client and every operating system. The basic format is: mailto:address@example.com?subject=Your%20Subject&body=Your%20Body. This generator handles all the URL encoding automatically — you just type your email address and text in plain language.
Advanced mailto: URIs can include CC (carbon copy) and BCC (blind carbon copy) recipients using the format: mailto:to@example.com?cc=cc@example.com&bcc=bcc@example.com&subject=Subject&body=Body. Use the Advanced tab above to set CC and BCC fields.
Keep Email Body Short for Better QR Codes
Every character in the email body increases the QR code's data density, making the code more complex and slightly harder to scan from a distance. For the most reliable scan at all sizes, keep the pre-filled body under 200 characters. Use the subject line to convey the most important context — it's shorter and less likely to cause scanning issues on very small prints.
Pro Tips for Email QR Code Campaigns
- Use source-specific subjects: Use different subjects for each placement — "Card Enquiry" for business cards, "Flyer Enquiry" for flyers — so you know exactly where each email came from.
- Add your company logo as the QR centre: Familiar branding at the QR centre builds trust. People are more likely to scan a QR with a recognisable company logo than a generic code.
- Add a call to action: Print "Scan to email us" or "Scan to request a quote" near the QR. Explicit instructions increase scan rates by 25–40%.
- Test before printing: Scan your QR on both an iPhone and an Android to confirm the email app opens correctly and all fields are populated as expected.
- Use Level Q error correction for logos: If adding your logo to the QR centre, use Q or H error correction to ensure the code remains scannable even with the logo covering part of the pattern.
