A QR code can open the user's email app with a pre-filled recipient address, subject line, and body text. One scan → the email draft is ready → the user just taps send. This reduces the friction of contacting you by email from physical materials.
How It Works
The QR code encodes a mailto: URL. This is a standard that all phones and email apps recognize:
mailto:hello@yourbusiness.com
When scanned, the phone opens the default email app with the "To" field already filled. The user writes their message and sends.
You can also pre-fill the subject and body:
mailto:hello@yourbusiness.com?subject=Inquiry%20from%20flyer&body=Hi%2C%20I%20saw%20your%20flyer%20and%20would%20like%20to%20know%20more.
Spaces are encoded as %20, commas as %2C. The user sees a complete draft and just taps send.
Create the QR Code
At qree.app, select the Email tab in the QR generator. Enter the email address, subject line, and body text. The tool handles the URL encoding automatically. Download your QR code.
Alternatively, build the mailto URL manually and paste it in the URL tab.
Use Cases
Business cards. A QR that opens an email to you. The sender doesn't need to type your address — especially useful for complex email addresses.
Storefronts. "Email us for a quote — scan here." Pre-fill the subject: "Quote request from storefront."
Product packaging. "Questions about this product? Scan to email our support team." Pre-fill the subject with the product name.
Conference badges. A QR on your badge that lets people email you. Pre-fill: "Met at [Conference Name]" so you know the context.
Flyers and posters. "Interested? Scan to email us." Pre-fill the body with "I saw your flyer about [topic] and would like more information."
Customer support. A QR on the product or in the manual: "Need help? Scan to email support." Pre-fill the subject with the product model for faster routing.
Pre-Filled Messages Save Time on Both Ends
The pre-filled subject and body aren't just convenient for the sender — they help the recipient too. A subject line like "Inquiry from event flyer — March 2027" tells you immediately where the lead came from. A body that says "I'm interested in your catering services for approximately 50 people" gives you context before you even reply.
Think of the pre-filled text as a form that the user can edit. They'll modify it if they want, but the default gives structure.
Email QR vs Contact Form QR
Email QR (mailto:) opens the user's email app. No website needed, works offline once the email app is open. But you can't control what the user writes, and there's no structured data collection.
Contact form QR (link to a Google Form or website form) opens a web page with structured fields. Better for collecting specific information (name, phone, topic). Requires internet. Gives you structured data.
Choose email QR when: the interaction is conversational, the recipient is a specific person, or you don't need structured data.
Choose form QR when: you need specific fields filled, you want to route inquiries automatically, or you need analytics on submissions.
Tips
Keep the pre-filled text short. A long body text can look spammy. One sentence suggesting the context is enough. Let the user add their actual message.
Test on both iOS and Android. The mailto link should open the default email app. Some phones might show an app chooser if multiple email apps are installed.
Include the email address visually. Print the email address in text alongside the QR. Some people prefer to type or copy the address rather than scan.
qree.app's Email type handles encoding. No need to manually URL-encode special characters — the generator does it for you.
