Does scanning an Email QR Code send the email automatically?

No. Mobile operating systems never send emails silently in the background without user consent. Scanning the code opens the user's default email app with your address, subject, and body pre-filled, allowing them to add details and tap Send.

Which email app opens when someone scans the code?

Whichever email application the person has set as their default on their iPhone, Android phone, or tablet — such as Gmail, Apple Mail, or Outlook.

Why should I include a pre-filled subject line?

A specific subject line (like 'Support Request — Sticker #4' or 'Wholesale Inquiry') helps the user understand what to write and lets you set up automatic inbox filters in Gmail or Outlook.

Do Email QR Codes expire?

Never. Because your email address and subject line are encoded directly into the static QR pattern, the code will work forever as long as your email address remains active.

Is my email address harvested or stored by ToolBuddy?

No. Everything runs locally inside your browser tab. We never collect, store, or transmit your email address.

Technical Specifications & Best Practices

✓For security and anti-spam reasons, scanning an Email QR Code opens a pre-filled draft in the user's mail app — the user still taps 'Send' to transmit the email.
✓Keep the pre-filled starter body concise (under 250 characters) so the QR matrix stays clean and easy to scan at small print sizes.
✓Uses the universal RFC 6068 `mailto:` URI standard supported by Apple Mail, Gmail, Outlook, and Yahoo Mail.
✓Generated 100% locally in your browser with zero tracking redirects or expiration dates.
