A mailto QR code (also searched as “QR code mailto” or “QR code that opens email”) opens your email app with a new draft. Start with the Mailto / Email QR code generator.

Mailto formats (copy/paste)#

Basic: mailto:hello@example.com
Subject: mailto:hello@example.com?subject=Hello
Subject + body: mailto:hello@example.com?subject=Hello&body=Hi%20there

Step-by-step#

  1. Enter the recipient email address.
  2. Optional: add a subject and message.
  3. Scan-test on iPhone and Android (some scanners ignore subject/body).
  4. Download SVG for print or PNG for sharing.

Tips (avoid scan failures)#

  • Keep the subject/body short (long mailto strings make the QR denser).
  • Use SVG for sharp printing and keep a clear quiet zone.
  • Troubleshooting: QR not scanning fixes.

If you need analytics#

Mailto opens an email draft and may be hard to track. If you need measurement, use a URL QR to a contact page with UTM parameters instead. See UTM tracking for QR.

For other payload types, see URL/Phone/SMS/Email payload formats.
