Local Processing Only

How to Use

Enter recipient email address.

Enter Subject.

Enter Body text template.

Scanning the code launches the mail app.

Overview

Launch the mail app not just with an address, but with a subject and body template ready. Saves users typing effort and ensures standardized inquiries for smoother communication.

Capabilities

Pre-fills recipient, subject, and body templates into the scanner-side mail client.

Use Cases

Useful for support contacts, quote requests, and event registration workflows.

How It Works

Uses `mailto:` URI payloads that invoke the device default mail handler.

Cautions

Long body templates can be truncated by client behavior; keep message templates concise.

Technical and Practical Benefits

Marketing Applications

Asking users to write emails from scratch causes drop-offs. Pre-filling "Campaign Entry" in the subject and "Name:" in the body reduces friction and can significantly improve response rates.

Technical Specifications

                Schema: `mailto:<email>?subject=<subject>&body=<body>`
Encoding: Requires URL encoding (Percent-encoding).

FAQ

Is my email address and message sent to a server?

No. QR creation runs locally in your browser, and your input is not sent externally.

Will scanning send the email automatically?

No. It only opens the compose screen. The user must tap Send manually.

Can I force a specific app like Gmail or Outlook?

No. This uses the standard `mailto:` scheme, so the device’s default mail app determines what opens.

How long can the subject/body be?

Very long bodies may be truncated depending on the mail app. Keep it short and link to details when possible.

Does it support line breaks and non‑English text?

Generally yes, but formatting can vary by mail client. Scan-test before publishing.

Can I send to multiple recipients?

Some clients support comma-separated addresses in the To field, but behavior varies. Using a single recipient is the most reliable option.

What happens if someone scans on a PC?

It depends on the environment. It may open a default mail app or a webmail flow.

I’m worried about exposing an email address publicly

Publishing an address can increase spam risk. Consider using a dedicated contact alias or rotating address.
