What is an Email QR Code Generator?
An email QR Code Generator turns a recipient address, subject, and message into a QR code that opens a phone's mail composer with those fields already filled in. Instead of dictating an address and asking someone to type it correctly, you print or display the code; they point a camera at it, tap the prompt, and a new email to you appears ready to send. It removes the transcription errors that turn a printed address into a bounced message.
The code encodes a mailto: link, the same URI scheme a mailto hyperlink uses, defined in RFC 6068. The recipient sits in the link path and the subject, body, CC, and BCC become percent-encoded query parameters, so a subject line with spaces or an ampersand survives intact. That string is then encoded as a QR matrix with Reed-Solomon error correction following ISO/IEC 18004, the specification every scanner app implements, which is why the result works with the built-in camera on any modern phone rather than needing a special reader.
Any QR code email generator can be checked against what it encodes. Enter [email protected] as the Recipient email and Order #1042 & returns as the Subject, and this QR code generator for email stores mailto:[email protected]?subject=Order%20%231042%20%26%20returns. The # and & are percent-encoded, so the subject arrives whole instead of being cut off at the ampersand, and the payload fits a version 5 code, 37 modules wide, at error correction M. Scanned, it opens a new message with both fields filled in.
Everything runs inside your browser. The address and message you enter are never uploaded, logged, or attached to a scan-tracking dashboard - the encoding happens in JavaScript on your device, and the tool keeps working with the network unplugged once the page has loaded. The QR code it produces is static, meaning the mailto link lives in the image itself with no short URL in the middle that could expire or be switched off. It is built for business cards, email signatures, flyers, product packaging, and event signage where you want to make getting in touch a single scan.
How to use the Email QR Code Generator?
Enter the recipient address
Type the email address the message should go to. This is the only required field; double-check it, because everyone who scans the code will email this address.
Add a subject and message (optional)
Fill in a subject line and body to pre-populate the email, and add CC or BCC addresses if you want copies routed automatically. Leave any of these blank to let the sender write their own.
Adjust error correction and colours
Raise error correction to Q or H if the code will be printed small or placed behind glass, and set foreground and background colours to match your design while keeping strong contrast.
Download and print
Export a vector SVG for print and signage, or a PNG from 128 to 2048 pixels for a screen or slide. Test the code with two or three phones before you produce a batch.
Key Features
Pre-filled email on scan
Produces a standard mailto: payload that iOS and Android open in the mail composer. The recipient, subject, and body are already there, so the sender only has to tap send.
Subject, body, CC and BCC
Fill any combination of fields. CC and BCC route copies automatically, and the body keeps its line breaks so multi-line messages arrive formatted as written.
Safe percent-encoding
Spaces, ampersands, and other reserved characters in your subject or body are percent-encoded per RFC 6068, so tricky text encodes without breaking the mailto link.
SVG and PNG export
SVG stays razor-sharp from a business card to a poster; PNG exports from 128 to 2048 pixels for screens and documents. Both download with no watermark and no account.
