Email QR Code Generator for Signatures & Marketing Campaigns
Email QR Code Generator for Signatures & Marketing Campaigns
An email QR code removes the friction of typing an address. When scanned, it opens the user's default mail app with the recipient and optionally a subject line already filled in.
This guide covers how to use email QR codes for signatures, marketing, support, and events.
How Email QR Codes Work
Email QR codes use the mailto: protocol. When a phone scans the code, it parses the email address and subject and opens the email composer.
Example use cases:
- Customer support
- Sales inquiries
- Newsletter subscriptions
- Event RSVPs
- Feedback collection
- Recruitment applications
Why Use Email QR Codes?
- Higher response rates: Users send the email instead of copying the address
- Better accuracy: No typos in the email address
- Consistent subject lines: Pre-fill subjects for campaign tracking
- Mobile-friendly: Perfect for flyers, posters, and packaging
- No landing page needed: Direct to the inbox
