Create an Email QR Code

An email QR code opens a prepared draft in the mail app after scanning. You choose the recipient address and can add an optional subject and message. It saves typing on flyers, products, and service material while reducing misspelled addresses. The generator creates the code instantly in your browser, and no email details are sent to a server.

  • All data stays in your browser — nothing is sent to a server.
  • Blazing fast — generated instantly, no server in between.
  • Never expires — the code works forever, no redirect service in between.
  • No tracking, no cookies, no signup.

Complete the required fields to generate the QR code.

How to create an email QR code

Write the template so it remains clear to every scanner. A short message produces a less dense code and leaves room for the sender to add personal details.

  1. Enter the intended recipient address. Check the domain and spelling carefully because the address is stored directly in the QR code.
  2. Optionally add a recognizable subject and a short message, such as a reference number, support question, feedback prompt, or registration request.
  3. Scan the preview on iOS and Android. Confirm that the expected mail app opens and every completed field appears correctly in the draft.
  4. Download the PNG, place it with strong contrast and a clear margin, and test it again at the final print or screen size.

The mailto format and encoded content

An email QR code uses a mailto link. The address follows mailto: directly. Subject and message are added only when provided and are safely encoded as URL parameters. An example payload looks like this:

mailto:support@example.com?subject=Product%20question&body=Hello%20team

Spaces, non-ASCII characters, line breaks, and ampersands appear percent-encoded in the technical content. The mail app converts them back into readable text when opening the draft. The code contains no attachment or login details and cannot send anything itself. Without a subject and body, the payload contains only mailto: and the recipient address.

Practical uses for email QR codes

On packaging or instruction manuals, an email QR code can prepare a support request with the correct subject. Event organizers use one for registrations and questions, while sales teams place it on brochures for quote requests. Feedback cards, exhibitions, property listings, and product displays also benefit from a correctly transferred contact address.

A specific subject helps route incoming mail, for example “Question about Product A” or “Workshop registration.” Leave space in the message for personal information. Publicly displayed codes should use an address intended for external requests; private mailboxes and internal-only distribution addresses are poor choices for open material.

Compatibility and limitations

After scanning, the device normally opens its configured default mail app. If no app or account is configured, the operating system may show a chooser, an error, or no useful action. The draft can look slightly different in Apple Mail, Gmail, Outlook, and other applications.

The QR code is static. Its recipient, subject, and text cannot be changed after printing. Long templates create a denser pattern and leave less room for personalization. This generator deliberately supports one address, subject, and message; CC, BCC, and attachments are outside the generated format.

Privacy: The recipient, subject, and message are encoded entirely within your browser. OnlineToolkit.ch does not receive, store, or send those details.

Frequently asked questions about email QR codes

What happens when someone scans an email QR code?

The smartphone recognizes the mailto content and normally opens a new draft in the preferred mail app. It fills the recipient, subject, and message. The person can review and edit everything before choosing to send it.

Is the email sent automatically?

No. A QR code can only prepare the draft. The operating system requires a deliberate user action, and the mail application sends the message only after the person confirms it.

Are the subject and message required?

No. Only the recipient address is required. An empty subject or message is not appended as a parameter. You can therefore provide either a complete template or simply a reliable contact address.

Do special characters and line breaks work in an email QR code?

Yes. The generator encodes special characters and line breaks with standard URL encoding. Modern mail apps restore them as readable draft text. Unusually long or multilingual templates should still be tested on the intended devices.

Does an email QR code expire, and are the details private?

The static code does not expire or depend on an OnlineToolkit.ch service. It remains useful while the recipient address is valid. Creation is local, but anyone who can access the finished QR code can read its embedded content.
