Email QR code generator
Create a QR code that opens a pre-filled email with recipient, subject, and message. Free PNG and SVG downloads.
There's an API for this — free, no key
Everything this generator does is also one GET request away. Build any QR code above, press API, and you get a shareable URL that renders the exact same design — PNG or SVG, any size up to 2048px, all dot styles, marker shapes, and colors.

An email QR code opens the scanner's mail app with a message already drafted — your address in the To field, and optionally a subject and body filled in. They just press send. It is a frictionless way to collect support requests, feedback, RSVPs, or leads from posters, packaging, and business cards.
What an email QR code encodes
The code holds a standard mailto: link — the same one a website email button uses — with your recipient address and any subject and body you add. Nothing is stored on our servers; the whole draft is encoded in the pattern. Because it is a plain mail link, every phone and mail app understands it without a special reader.
Prefilling the subject and message does real work: it lowers the barrier so people actually send, and it keeps incoming mail consistent and easy to filter or route.
What happens when someone scans it
On iPhone and Android the camera recognises the mail link and offers to open a new message with your address, subject, and body already in place. Crucially, nothing sends automatically — the person sees the drafted email and taps send themselves. That confirmation step is why an email code is safe to put on public print: it starts a message, it never fires one off.
Keep it short and it scans better
A long prefilled body makes the pattern dense and slower to scan, so keep the message to a sentence or two and let people write the rest. Use a real, monitored inbox, keep strong contrast and a clear quiet zone, and download a PNG for screens or an SVG for print.
When a landing page beats a mail draft
An email code is perfect for one-tap contact, but if you would rather send people to a form, a help centre, or a campaign page — and measure it — point a short link QR code there instead, so you can see scans by source and device and change the destination later. Some teams print both: a mail code to reach a human, and a tracked link for the offer. For chat-first contact, a WhatsApp code often converts better, and there are comparisons on the blog.
Keep the replies clean and routed
An email code that works too well can flood a personal inbox, so aim it at an address you can manage. A dedicated, monitored mailbox — support@, hello@, rsvp@ — keeps campaign replies out of your day-to-day mail and lets a team share the load. Prefilling a specific subject line is quietly powerful here: a consistent subject makes incoming mail trivial to filter, label, or auto-route, so a poster campaign and a packaging insert land in separate, sortable piles.
Match the channel to the audience, too. An email code suits formal enquiries and anything with attachments; for a quick question, a WhatsApp code or an SMS code gets a faster reply. And if what you really want is a form submission you can measure, send people to a page via a trackable short link instead of a mail draft.
Other QR code types
Need a different kind of code? Try the SMS QR code and WhatsApp QR code. Any code here can become a dynamic QR code you edit after printing and track on every scan — and if you just need a short link, the URL shortener counts every click.
