How we verify this guide

Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.

Recommended templates

Email QR Code
Generate a mailto QR code that opens your email app with recipient and optional subject/body prefilled.
Business Card QR Code
Create a business card QR that saves a vCard, then check contact density, print size, quiet zone, and the real camera flow before ordering cards.
vCard QR Code
Make a vCard (contact info) QR code so people can save your details in one scan.
Phone QR Code
Scan to start calling instantly (tel: link).
URL QR Code
Convert a website link to a QR code instantly, then download a clean SVG or PNG.
Redirect QR Code
Create a redirect QR code for campaigns, menus, packaging, posters, and any QR that may need a controlled destination path.

Use cases & print ideas

Matching pages that explain where this QR type works best before you open the generator.
vCard Contact QR Print Use Cases
Use these print examples when the next step should be saving a contact, not typing details or visiting a plain web page.
Redirect QR Code Use Cases
Use Redirect QR for a controlled destination path; only hosted dynamic QR lets the printed asset stay fixed while the destination changes after launch.

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.
