What Does an Email QR Code Do?
When someone scans your email QR code, their phone's default email app opens with the recipient address, subject line and message body already filled in. They just review and tap Send.
It's a small thing, but removing the friction of typing an email address reduces the chance of errors and increases the chance someone actually follows through. We see this used most often on:
- Business cards — scan to send an inquiry or introduction email instantly
- Product packaging — scan to contact support or register your product
- Event materials — scan to send your contact request to the exhibitor
- Flyers and print ads — scan to request more information
- Restaurant feedback cards — scan to send feedback directly to the manager
💡 The email is never sent automatically. Scanning opens the email app with fields pre-filled — the user still reviews and taps Send. This is by design. The standard mailto: protocol doesn't allow auto-sending.
Tips for Writing the Pre-filled Message
The pre-filled message is optional, but when used well it can significantly increase response rates. A few things that work:
- Keep it short — one or two sentences max. The sender will want to personalize it anyway.
- Identify the context — something like "I scanned your QR code at [event name]" helps you remember where the contact came from.
- Make the subject descriptive — "Product inquiry from [source]" is much more useful in your inbox than "Hi".
✅ Test before printing. Scan your QR code and confirm the email app opens with the correct address, subject and message. A typo in the email address means all responses go nowhere.
