Email QR Code Generator

How to create an email QR code

1. Enter the address that should receive the messages.
2. Add a subject. A clear subject helps you sort incoming mail, for example "Feedback – spring catalog".
3. Optionally write a short message or a prompt that the sender can edit, such as "Tell us what we could do better:".
4. Scan the preview: your mail app should open with all fields filled in.
5. Download the PNG or SVG and add it to your flyer, packaging, sign or slide.

How it works

The code contains a mailto link, the standard way to describe an email in a URL, defined in RFC 6068. For the recipient hello@example.com, the subject Feedback and a one-line message, QR Hut builds:

mailto:hello@example.com?subject=Feedback&body=Hi%2C%20I%20would%20like%20to%20share%20some%20feedback%3A

The subject and message are percent-encoded with UTF-8, so spaces, accents and punctuation survive the trip. Line breaks in the message are converted to CR+LF (%0D%0A), as RFC 6068 specifies, and any spaces in the address are removed. You can see the finished link under Show encoded text.

When the code is scanned, the phone recognizes the mailto: prefix and offers to open the default mail app with a new draft. Nothing is sent automatically. This example is 105 characters long and becomes a version 7 code (45 × 45 modules) at error correction level M; longer messages make the code denser. As with every QR Hut tool, the link is created in your browser and never sent to our servers.

Tips

• Use the subject to track where emails come from. Make one code per poster, product or location with a different subject line, and you will know which one people scanned without any tracking service.
• Keep the message short. A one-line prompt works better than a pre-written letter and keeps the code easy to scan.
• Prefer a role address. Anyone who scans the code can read the address, so a dedicated mailbox such as feedback@ or support@ is better than a personal one.
• Explain the code. A label like "Scan to email us" sets the right expectation; most people assume a QR code opens a website.
• Offer an alternative. Print the email address next to the code for people who prefer to type it.

Common uses

• Customer feedback on receipts, table cards and hotel room cards.
• Support requests on product packaging and in printed manuals, with the product name in the subject.
• Maintenance reports in shared buildings: "Report a problem – Laundry room 2".
• Lost-and-found labels on luggage, laptops and keys.
• Event RSVPs and simple sign-up requests.
• Assignment submissions or questions in classrooms and workshops.

Limitations

• The scanning phone needs a mail app configured for email links; people who only use webmail may see a prompt or nothing at all.
• There are no CC or BCC fields, and attachments are not possible in a mailto link.
• A few mail apps ignore the pre-filled message or shorten very long ones. Keep important information in the subject.
• You only receive something if the person actually sends the draft. For structured answers, a link QR code to an online form may suit you better.
• The code is static: to change the address or subject, make a new code.
