What Is an Email QR Code?

An email QR code uses the mailto URI scheme to create a scannable code that, when tapped, opens the device's default email app with the To address, Subject, and Body already filled in. The recipient just reviews and hits Send — no typing required. According to Statista, 4.48 billion people use email globally as of 2024, making the mailto: URI one of the most universally supported communication protocols on any device.

The mailto URI Format

The QR code encodes a string like:
mailto:hello@example.com?subject=Your%20Subject&body=Your%20message%20here

Special characters in the subject and body are URL-encoded (spaces become %20, line breaks become %0A, etc.). This generator handles encoding automatically — just type naturally in the fields above. The mailto: URI scheme is defined by RFC 6068 and supported by all major email clients including Gmail, Outlook, and Apple Mail.

Use Cases

Contact forms replacement: Instead of a web form, place an email QR code on your website's printed materials. Visitors scan to reach you directly without filling out a form. Feedback collection: Place a QR code on restaurant tables, hotel rooms, or product packaging with a pre-filled "Share your feedback" subject. HubSpot research shows that adding a pre-filled subject line increases email open rates by 26%, so a well-crafted subject is worth including. Support desks: Print at service counters so customers can email support without hunting for an address. Conference booths: Let visitors email you their details by scanning a code with a pre-written "I'd like your brochure" message.

Email QR vs. Contact Form

Web contact forms require an internet connection, a browser, and often a CAPTCHA. An email QR code works with whatever email app the user already has — Gmail, Outlook, Apple Mail — and the message goes directly to your inbox with no intermediate system. It's simpler for the user and simpler for you to manage.

Tips for Better Results

Keep the pre-filled message short and context-relevant. A long body makes the QR code denser, which can be harder to scan in poor lighting or at small print sizes. If your message is long, put just a subject line and let the user write the body. Always test your QR code by scanning it yourself before printing.

Frequently Asked Questions

What is an email QR code?

An email QR code encodes a mailto URI that opens the device's default email app with the To address, Subject, and Body pre-filled when scanned. The user reviews the draft and taps Send — no typing required. It is used on business cards, signage, and printed marketing materials.

What is the mailto URI format?

The format is mailto:address@example.com?subject=Subject&body=Message. The To address follows "mailto:" and Subject and Body are URL-encoded query parameters. This generator handles all encoding automatically — just type naturally in the fields above.

Will it open Gmail or the phone's default email app?

It opens whatever email app the user has set as default. On iPhones that is typically Apple Mail; on Android it depends on the user's settings. If Gmail or Outlook is set as default, those apps open instead. The mailto: URI scheme is supported universally.

Can I pre-fill the email subject and body?

Yes. Fill in the Subject and Message Body fields above and both are automatically encoded into the mailto URI. HubSpot research shows that a pre-filled subject line increases email open rates by 26%, so including a clear, relevant subject is worth doing.

Does the email send automatically when scanned?

No. Scanning opens the email app with a pre-addressed draft. The user must tap Send manually. No email is ever dispatched without the user's explicit action — this is a built-in security behavior of the mailto: scheme.

Which email apps support mailto links?

All major email clients support mailto: links — Gmail (iOS and Android), Apple Mail, Microsoft Outlook, Yahoo Mail, Spark, and Thunderbird. The mailto: URI scheme is defined by RFC 6068 and has been universally supported for over two decades.
