How to Create an Email QR Code — Open a Compose Window Instantly

An email QR code opens your recipient's email app with your address, subject line, and even body text already filled in. Instead of asking customers or contacts to look up your email address and compose a message from scratch, they scan and tap Send. Here's how to create one for free.

How Email QR Codes Work

Email QR codes encode a mailto: URL — the same protocol web browsers use to open email compose windows from "Contact Us" links. When scanned:

1. The phone recognizes the mailto: protocol
2. The default email app opens
3. The compose window pre-fills your address and any subject/body text you encoded
4. The user taps Send (or edits the message first)

Works on iPhone (opens Mail or Gmail depending on default), Android (opens Gmail, Outlook, or the default mail app), and any device with an email app configured.

Creating a Basic Email QR Code

A basic email QR code (address only, no pre-filled subject or body) uses a simple mailto: URL:

mailto:info@yourcompany.com

1. Go to UnlimitedQRCodes.com
2. Select URL as the QR code type
3. Enter mailto:YOUREMAILADDRESS
4. Generate and download as SVG or PNG

Creating an Email QR Code with Pre-Filled Subject and Body

A more powerful option: pre-fill the subject line and body text. The URL format is:

mailto:info@yourcompany.com?subject=SUBJECT&body=BODY

URL-encode spaces as %20 and special characters appropriately. Examples:

• Product inquiry: mailto:sales@yourcompany.com?subject=Product%20Inquiry&body=Hi%2C%20I%20am%20interested%20in%20learning%20more%20about%20your%20products.
• Appointment request: mailto:appointments@yourdentist.com?subject=Appointment%20Request&body=I%20would%20like%20to%20schedule%20an%20appointment.
• Feedback: mailto:feedback@yourrestaurant.com?subject=Feedback%20from%20my%20visit&body=My%20experience%20today%20was%3A

Paste the complete mailto: URL with parameters into UnlimitedQRCodes.com's URL field and generate.

Where to Use Email QR Codes

Business Cards

A small email QR code on your card opens a compose window to you instantly — better than printing a tiny email address that's hard to type correctly. Combine with a vCard QR code: one code for "save my contact," one for "email me now."

Product Packaging

A QR code linking to mailto:support@yourcompany.com?subject=Product%20Support gives customers an immediate path to contact support without navigating your website. Reduces support ticket creation friction for customers who prefer email.

Printed Menus and Brochures

Catering menus, event brochures, and service menus can include an email QR code for inquiries: "Interested in our catering services? Scan to send us your event details." Pre-fill the body with prompting fields: "Event date: / Guest count: / Location:"

Thank-You Cards and Post-Purchase Inserts

Include an email QR code in post-purchase thank-you inserts: "Questions or feedback? Scan to email us directly — we respond within 24 hours." This personalizes the support touchpoint and builds customer trust.

Email QR Code Limitations

• Requires the phone to have an email app configured — users who only use webmail (gmail.com in a browser) may see an error or a prompt to set up an email app
• Cannot track whether the email was actually sent — only the compose window opens
• Some mailto: URLs with very long body text may not work on all email apps — test thoroughly

For these reasons, email QR codes work best as a convenience feature for users who have email apps configured — which is the majority of smartphone users in the US, but not 100%.

Frequently Asked Questions

How does an email QR code work?

It encodes a mailto: link. When scanned, the default email app opens with your address and optional subject/body pre-filled. The user taps Send.

Can I pre-fill the subject and body of an email QR code?

Yes — use the full mailto: URL format: mailto:email@you.com?subject=Subject&body=Body. URL-encode spaces as %20.

What's better for a business card — email QR code or vCard QR code?

vCard QR code is better for long-term contact saving. Email QR code is better for immediate action (inquiry, support, feedback). Use both if space allows.
