Email QR Generator

Create a QR code that opens a pre-filled email.

Scanning opens the phone's email app with these fields filled in. The sender still reviews and sends the message themselves.

How to use Email QR Generator

What this tool does

An email QR generator turns an email address — optionally with a ready-made subject and message — into a QR code. When someone scans it, their phone opens its email app with those fields already filled in. They just review and send. It removes the friction between “I want to get in touch” and an actual message landing in your inbox.

This tool builds the standard mailto: link behind the code, encodes the subject and body safely, and renders the QR code live as you type. Every part of it is computed in your browser, so nothing you enter is uploaded.

Why you might need it

Most ways of inviting contact ask the other person to do work: find your address, open their mail app, think of a subject, write an opening line. Each step loses people. An email QR code collapses all of it into one scan and one tap.

That makes it useful wherever you want to make getting in touch effortless. On product packaging or a manual, a code labelled “Need help?” opens a support email with the subject pre-set — so the request reaches the right queue already categorised. At an event, a check-in or registration code drops attendees into a pre-written signup email. On a flyer, poster or shelf talker, a code captures interest the moment someone feels it, instead of hoping they remember later. In a customer-support context, a pre-filled subject like “Order issue” routes messages correctly before a human ever reads them.

Because the subject and body are pre-filled, you also get more useful messages: the sender starts from a structured prompt instead of a blank screen.

How to use it

  1. Enter the recipient email address — the only required field.
  2. Optionally add a subject to pre-fill the subject line.
  3. Optionally add a message body — a prompt or template the sender can edit.
  4. Adjust the size, error correction and colours in the preview.
  5. Download the code as a PNG for screens or an SVG for print.

Use case examples

A few patterns work especially well. A support QR code on packaging with the subject set to a product name or SKU means incoming mail is pre-sorted. An event signup code on a poster, with a subject like “Register — Spring Workshop”, turns a glance into a lead. A feedback code on a receipt or table card, with a friendly pre-written opening line, lowers the bar enough that people actually write in. A lead-capture code in a printed brochure connects an interested reader to your sales inbox before the brochure is set down.

Keep the pre-filled body short and genuinely helpful — a prompt, not a script. The sender should feel guided, not boxed in.

Tips for a reliable email code

The longer the pre-filled subject and body, the more data the QR code carries and the denser its pattern becomes — a dense code is harder for a camera to read quickly, especially from a distance or at a small printed size. Keep the message concise.

Maintain strong contrast: a dark code on a light background scans best, and low-contrast colour pairs fail on many cameras. For print, download the SVG so the code stays sharp at any size, and raise the error-correction level to Q or H if the code will sit somewhere it might get scuffed or partly covered. Always test the finished code with a real phone before printing at scale — and because the whole mailto: link is assembled on your device, nothing you type here is ever uploaded.

Frequently asked questions

Is the email address or message I enter sent anywhere?
No. The QR code is built in your browser from the fields you type — the recipient address, subject and body never reach a server. You can confirm this in your browser's Network tab; nothing is uploaded, logged, or stored.
Does scanning the code send the email automatically?
No, and that is by design. Scanning opens the phone's email app with the address, subject and body already filled in. The person still reads the message and presses send themselves, so they stay in control.
Which email app does it open?
Whichever app is set as the device's default mail handler — Gmail, Apple Mail, Outlook, and so on. The code uses the standard mailto: link that every email app understands, so it works regardless of the user's setup.
Can I leave the subject or body blank?
Yes. Only the recipient address is required. Add a subject, a body, both, or neither — a code with just an address simply opens a blank email to that recipient.
Why is my email QR code not scanning?
Usually it is contrast or capacity. Keep a dark code on a light background, and remember that a long pre-filled body makes the code denser and harder to scan. Shorten the message or lower the error-correction level if the code will not read.
