An email QR code saves people from typing your address by hand. They point a camera at it, and a new message to you opens with the subject and first line already written. Here is how to make one and where it works best.
TL;DR Open the email QR code generator, enter your address, add an optional subject and message, then download a PNG or SVG to print or post. Scanning opens a ready-to-send draft.
What to put in the code
You need the email address. Everything else is optional but useful. A subject line tells you at a glance why someone is writing, which helps you sort replies. A short starter message can prompt the detail you actually need, such as a name, an order number or a preferred time.
Keep the pre-filled message short. People will add to it, and a wall of text in a draft feels like a form rather than an email.
Where to use it
Email QR codes work well on printed material where someone cannot click a link: a flyer, a poster, packaging, a market stall sign, or a slide at the end of a talk. They also help on a business card when you want one tap to a message rather than a saved contact.
Put a line of text next to the code so people know what it does, for example “Scan to email us about bulk orders.” A bare code makes people hesitate.
Make it look right
The code does not have to be plain black. You can match your colors and drop a small logo in the center, as long as the foreground stays clearly darker than the background. Test the styled version with a couple of phones before a print run so you know it scans on the first try.
Make one now
The email QR code generator builds the code in your browser, so your address and message are never uploaded. Fill in the fields, style it if you like, and download a sharp PNG or a print-ready SVG.
