How to create an email QR code
Enter the recipient email address in the To field. Optionally add a subject line and a pre-filled message body. Click Generate Email QR Code. Download the result as PNG for digital use or SVG for print. Anyone who scans the code will have a new email ready to send in their mail app.
What is a mailto QR code?
An email QR code encodes a mailto: URI - the same standard used in email links on websites. When a phone camera reads the code, the operating system recognises the URI scheme and opens the default mail app with the address, subject, and body fields populated. The sender reviews the pre-filled content and taps Send.
When should I use an email QR code?
Email QR codes are well suited for physical print materials where you want to invite contact: business cards, product registration cards, brochures, conference booth displays, and product packaging. A pre-filled subject like "Product warranty enquiry" or "Request a quote" helps direct messages to the right inbox or team if you use email routing rules.
Email QR code versus URL QR code: which should I use?
Use a URL QR code when you want to direct someone to a web page - a contact form, portfolio, or booking system. Use an email QR code when you want the person to send you a direct message without navigating to a website. Email QR codes work offline and do not depend on a landing page remaining live.
How large does an email QR code need to be?
The payload size depends on how much text is in the subject and body. A QR code with just an email address will be small and scan easily at 1.5 cm × 1.5 cm on a business card. A QR code with a long pre-filled body will have more modules and may need to be printed larger. Keep the body text short - a sentence or two is enough - and the code will remain compact and reliable.
Frequently asked questions
What does an email QR code do?
When someone scans an email QR code, their device opens the default mail app with a new message pre-addressed to your email address. If you set a subject or body, those fields are also pre-filled. The sender just needs to tap Send.
Is the recipient address required?
Yes, the To address is the only required field. Subject and body are optional. You can create a minimal QR code that just opens a blank email to your address, or a fully pre-filled one with subject and message body.
Will it work on iPhone and Android?
Yes. The mailto: URI scheme is supported on all modern mobile operating systems and mail clients. Scanning the QR code opens the device's default mail app - whether that is Apple Mail, Gmail, Outlook, or another client.
Is my email address safe?
Your email address is encoded directly into the QR code image. Anyone who scans it or reads the raw QR data will see the address. Only use this with an email address you are comfortable making public. The address is never transmitted to any server by this tool.
What should I write in the pre-filled body?
A short prompt works well. For example: "I scanned your QR code and would like to enquire about [topic]." This gives the sender context and reduces blank-slate hesitation. Keep it brief - the scanner can always edit or replace the text before sending.
Can I use this on a business card or product label?
Yes. Download the SVG for print applications - it will be sharp at any size. A minimum print size of 1.5 cm × 1.5 cm is recommended for a business card. For larger print items like posters or signage, increase the size proportionally.
Is this tool free?
Yes. There are no charges, no account required, and no usage limits. All processing happens in your browser - nothing is sent to any server.
