RFC 6068 Mailto
Specification & Encoding Standards
Automated Mailto Client Routing
A mailto QR code launches the scanning device's default mail client — such as Apple Mail, Gmail, or Outlook — with the recipient address, subject line, and optional message body pre-populated. This removes friction for warranty registration, customer feedback lines, and RSVP submissions where you want clean, structured incoming messages. Avoid lengthy paragraph bodies in the mailto payload, as URI percent-encoding rapidly consumes byte capacity and increases QR module density.
RFC 6068 Mailto URI Implementation
We construct standards-compliant mailto URIs with proper URL percent-encoding for space and punctuation characters. iOS and Android mail application handlers intercept the URI and instantly present a composed draft message.
For customer support stickers and product labels, pairing a standardized subject line (e.g. 'Serial Number Support [A-102]') allows your email helpdesk software to route tickets automatically upon arrival.
Customer Support & Warranty Label Recommendations
Use standardized bracketed prefixes in the Subject field (e.g. "[Warranty Model-X]"). Helpdesk software such as Zendesk and Freshdesk automatically parse these tags to assign incoming tickets to the correct department.
Keep body drafts concise. Excessive paragraph text requires extensive percent-encoding (such as %20 for spaces and %0A for linebreaks), inflating the QR byte length and creating a dense matrix.
Frequently Asked Questions
Does the email send automatically when scanned?
No. For security and user consent, mobile operating systems open the mail client with the fields filled out, but the user must tap 'Send' themselves.
Can I pre-fill multiple recipient addresses?
Yes, you can separate multiple email addresses with commas in the recipient field, though keeping it to one address ensures maximum cross-client compatibility.
