What happens when someone scans an email QR code
The mail app on the phone opens with the address, subject and message already filled in. The person still has to tap send. Nothing is sent automatically, so a scan opens the message and the person decides whether to send it.
The built-in camera on current iPhones and Android phones reads the code, so the person needs no extra app.
How to make an email QR code
- Choose email as the code type, then enter the address the message should go to.
- Add a subject and a message if you want them. Both are optional.
- Check the scan result. Every design is test-scanned in the browser before download. If a design will not scan, the page says so and suggests a fix.
- Download the code as a PNG (512, 1024, 2048 or 4096 pixels) or as an SVG for print.
Good uses for an email QR code
- Customer support: put a code on a product box, manual or receipt so a customer can reach your support inbox in one scan.
- Feedback: add a code to a table card, sign or follow-up card that opens a feedback message.
- RSVPs: print a code on an invitation so guests can reply to you with one scan.
- Warranty registration: put a code in the box or on a card that opens a registration message.
- Email me this brochure: place a code on a booth sign or flyer so visitors can ask for your brochure in one scan.
Tips for a better email code
- Keep the message short. More text makes a denser code, and a denser code has to be printed larger. A sentence or two is usually enough.
- Write a specific subject. A subject such as RSVP plus the event name lets you filter replies or sort them into a folder.
- Point the code at an inbox that gets checked. For support or feedback, a shared inbox means replies do not depend on one person.
- Test before you print. Always test-scan a code with a phone before you print a large run.
Your address stays in your browser
The code is generated in your browser. The address, subject and message are never sent to or stored on our servers. We do not track scans, and a static code cannot be tracked by anyone.
Email codes are static
An email code is a static code. The address, subject and message are stored in the pattern itself, so they cannot be edited after printing. If the address changes, make a new code and replace the printed one. Static codes never expire and keep working even if 77-3.com disappears.
77-3.com cannot change where a printed code points or count scans. If you need either one, a dynamic code from another provider can do it, but every scan then goes through that provider, and some services document that their dynamic codes stop working when a free trial or subscription ends. Read static vs dynamic QR codes to choose between them.
Design and print size
Use dark modules on a light background. That combination scans most reliably, and light-on-dark codes do not scan on some older scanner apps. You can change colors and shapes on the custom QR code page.
Keep the quiet zone, the blank margin around the code, at 4 modules wide, as the standard specifies. Many codes still scan with a smaller margin, but do not go below 2. Print the code at least 2 cm (about 0.8 inch) wide, and use the SVG download for print. Scanning distance can be about 10 times the code's width, and a longer message needs a larger print.
