Email QR Code Generator

Make a free email QR code: when someone scans it, their phone opens a new email to your address with the subject and message already filled in, ready to send. The generator writes a standard mailto link and shows it in full. Download SVG, PNG, PDF or EPS.

Error correction

The share of the code that can be damaged and still be read (DENSO WAVE). Higher levels make a larger code.

Alignment

Printed in the file with the barcode, outside the quiet zone, in Helvetica or Courier so it looks the same in every format.

Colors

Contrast 21.0:1; estimated symbol contrast 100%.

Quiet zone (modules)4 · 4 · 4 · 4

Bar width reduction0 mil

Makes each bar thinner by this amount, to make up for ink that spreads on paper. Ask your printer for the value, or leave 0 for laser and thermal printing.

Rotation and backgroundNew0° · Filled

Rotation

In the preview, a checkered pattern shows the transparent areas. Print a transparent barcode only on a white or very light surface: scanners need the light quiet zone around it.

Margin and borderNew0 mm · no border

The margin is blank space outside the quiet zone, for cutting; the border is drawn at the outer edge. Both count in the print size.

Link tracking (UTM)NewOff

Adds utm_ parameters to the link so analytics can tell where a scan came from. A longer link makes a denser code.

      How to Create an Email QR Code

      Enter the address, an optional subject and message, and download the code.

      1. Type the email address that should receive the messages.
      2. Add a subject and a message if you want them filled in.
      3. Check the encoded mailto link, then download the code.
      4. Scan a test print and check the new email looks right.

      Email QR Code Fields

      An email QR code holds the address and, if you add them, a subject and a message.

      How an Email QR Code Works

      The code holds a mailto link, defined in RFC 6068, which phones hand to their email app.

      Encoding the Subject and Message

      Spaces become %20 and line breaks %0D%0A, as RFC 6068 shows in its examples; the generator encodes every character that needs it. Nothing is sent until the person presses Send.

      Email QR code with a mailto link to support@barcode.codes, the subject Hello and the message I scanned your code., with the spaces written as %20.
      A mailto link with a subject and a message, spaces as %20.

      Where Email QR Codes Help

      An email code saves people typing an address correctly, which matters for support, feedback and orders.

      Examples

      • Support: a code on a product that opens a support email with the product name in the subject.

        Email QR code that opens a message to support@barcode.codes with the subject Support: model X100.

      • Feedback: a code at a counter that starts a feedback email.

        Email QR code that opens a message to support@barcode.codes with the subject Feedback.

      • Requests: a code on a poster that requests a brochure.

        Email QR code that opens a message to support@barcode.codes with the subject Brochure request and a short message.

      Common Email QR Code Problems

      Problems usually come from the address or from a phone without an email app set up.

      What to Check

      • Address: a typo sends every message to the wrong place; test the code.
      • Email app: a phone needs an email app set up to open the message.
      • Long messages: a long message makes a dense code; keep it short.

      Frequently Asked Questions

      Does Scanning the Code Send an Email?

      No. It opens a new email with the details filled in; the person still presses Send.

      Can I Add a Subject and Message?

      Yes. Both are optional and are written into the code, encoded as the mailto format requires.

      Can I Add Several Recipients?

      The generator takes one address. Use a shared mailbox address if several people should receive the messages.

      Will It Work Without an Email App?

      The phone needs an email app set up to open the message; otherwise people see the address and can copy it.

      Is the Email QR Code Generator Free?

      Yes, with no account, watermark or download limit.

      Is the Address Sent to Barcode.codes?

      No. The code is built and drawn in your browser.
