Free email QR code generator

One scan opens a ready-to-send email

An email QR code generator converts your email address. Plus an optional subject and message. Into a single scannable code. Instead of asking someone to copy your address, open their mail app, and compose from scratch, you give them a code that opens a pre-filled draft. They scan, review, and send. QRHub's email tool is 100% free, requires no account, and is ready to print or share the moment you generate it.

It is perfect for any moment where you want a written response with a predictable format: collecting customer feedback, gathering event RSVPs, routing support requests, or making it effortless to reach you from a business card. Because it uses the universal mailto: standard, the draft opens in whatever email app the person already uses. On iPhone, Android, or desktop. With no extra downloads.

What is an email QR code and how does it work?

An email QR code encodes a mailto: link. The standard web format for opening a new email. The link carries the recipient address and can also include a URL-encoded subject and body. You never have to build that link yourself; QRHub assembles it correctly from the simple form above and turns it into a scannable code.

When someone scans the code with their phone camera, the device recognizes the mailto: link and opens their default email app to a new message with your address in the To field. If you added a subject and body, those appear pre-filled and ready to send. There is no form to design, no server to configure, and no chance of a mistyped address. This makes email QR codes a simple, reliable way to invite structured responses from printed and digital materials alike.

Pre-set the subject line so replies land organized and easy to sort or automate.

Where email QR codes shine

From feedback cards to job postings, a scan-to-email code fits anywhere you want a written, structured reply.

Feedback & reviews

Print it on receipts or table cards to collect structured feedback in one scan.

Event RSVPs

Add it to invitations so guests reply with a pre-filled subject and message.

Support requests

Business cards

Marketing & enquiries

Write a subject that gets replies

A clear, consistent subject line keeps your inbox organized and makes it easy to filter or automate responses.

  • Be specific: use subjects like “Feedback: Store Visit” or “RSVP: Launch Event.”
  • Stay short: a concise subject displays fully on mobile mail apps.
  • Add context in the body: A one-line prompt helps people know what to write.
  • Use a monitored inbox: Route the address to someone who replies promptly.

Best practices for scannable codes

A few details keep your code fast and reliable to scan.

  • Double-check the email address for typos before printing.
  • Add a clear call to action: “Scan to email us your feedback.”
  • Print at high contrast and at least 2×2 cm for close range.
  • Scan-test on iPhone and Android before mass printing.
  • Keep the pre-filled body short so it is easy to complete.
  • Avoid busy backgrounds or patterns behind the code.

Email QR code: frequently asked questions

Is the email QR code generator free?

Yes. QRHub's email QR code generator is completely free with no signup, no watermark, and no limit on how many codes you create. Generate a code, customize the colors, and download it in the format you need. All at no cost.

How does an email QR code work?

The code encodes a standard mailto: link containing your email address and, optionally, a pre-written subject and body. When someone scans it, their default email app opens a new message with those fields already filled in. They simply review and hit send.

Can I pre-fill the subject and body?

Yes. Add an optional subject line and message body when you generate the code. Both are encoded into the mailto: link, so the recipient sees a ready-to-send draft. This is ideal for feedback forms, support requests, RSVPs, and standardized enquiries.

Which email apps does it work with?

Email QR codes use the universal mailto: standard, which is supported by virtually every email client. Gmail, Apple Mail, Outlook, Yahoo, and more. On iOS, Android, and desktop. The message opens in whichever app the person has set as their default.

Do people need a special app to scan it?

No. Modern iPhones and most Android phones read QR codes directly from the built-in camera app. The user opens the camera, points it at the code, and taps the prompt that appears to open their email app.

Does a scan guarantee an email is sent?

No. Scanning opens a pre-filled draft, but the person still has to press send. Some may scan out of curiosity and close the app. Think of it as removing friction from the process rather than a guaranteed submission.

Can I customize the colors of the email QR code?

Yes. After generating, use the customization panel to change the foreground and background colors or set a transparent background so the code fits your branded materials. Always scan-test a customized code before printing to confirm it still reads reliably.

Where should I place an email QR code?

Anywhere you invite a written response: feedback cards, event invitations, product packaging, business cards, posters, receipts, and email signatures. It works especially well when you want a structured message with a consistent subject line.
