Email QR Code Generator
Scan to open a pre-filled email draft. Perfect for support pages, business cards, and event signups.
An email QR code (sometimes called a mailto QR) encodes a mailto: URL — when scanned, it opens the user's default email client with the recipient address already filled in, and optionally a pre-filled subject line and body. This removes the friction of typing your email address from a printed surface and increases the chance a curious passer-by actually sends the message.
The most common uses: customer-support signage on storefronts and product packaging ("Issue with your order? Scan to email us"); business cards with a quick-contact QR instead of a separately-typed email; event registration signs ("Email us to RSVP — subject line pre-filled"); conference booths with QR codes that pre-fill a "I'd like to learn more about [product]" template; printed surveys and feedback forms where the recipient scans to start the response email; real estate yard signs with "Email about this property" QRs.
This tool builds the mailto link in your browser. Enter the recipient address (or multiple addresses, comma-separated), optionally add a pre-filled subject and body, and the QR generates live. Customize the dot pattern, colors, and add an optional logo. Export at print or screen resolutions.
The pre-filled subject and body fields are especially powerful for support and lead-capture use cases. A printed sign saying "Scan to report an issue" generates a QR where the scanned email already has "Subject: Issue report — store #42" filled in. The user adds two sentences and hits Send — no thinking about what to write in the subject, no risk of the message landing in the wrong inbox because they used an unclear subject line. Same idea for lead capture: subject of "Demo request for [product]" pre-fills the customer's email so it's already categorized when it lands.

Frequently asked questions
What email client opens when a user scans an email QR code?
Whatever the user has set as their default mail handler. On iPhone, that's typically Mail or Gmail (depending on what the user picked in Settings → Mail). On Android, the user's default mail app. The QR doesn't dictate the client — it just opens a draft in whatever the user has configured. This is universally supported; we've never seen a mailto QR fail to open a draft on a modern phone.
Can I pre-fill the subject and body of the email?
Yes — both fields are optional and fully customizable. Type the subject you want (e.g. 'Demo request from QR scan') and the body (e.g. 'Hi — I scanned the QR code at your booth and would like to learn more about [product].'). When the user scans, their email client opens with both filled in. They can edit before sending, or send as-is.
Will the email QR code work if the user doesn't have a default mail app?
On iPhone, yes — the system always has Mail installed and configured (even if the user prefers Gmail in the web). On Android, the user must have at least one mail app installed for the QR scan to do anything; if they don't, the scan opens a 'no app to handle this' message. In practice, all modern phones ship with a mail handler so this is rarely an issue.
Can I include multiple recipients in one email QR code?
Yes — separate addresses with commas in the recipient field (e.g. sales@example.com, support@example.com). When the user scans, all addresses are added to the To field. You can also pre-fill the CC and BCC fields if needed; we don't expose those in the current form but the mailto spec supports them and we'd add them on request.
Is there a risk of my email being spammed if I post a QR code in public?
Yes — anyone who scans the QR can extract the email address and use it (manually or via an automated decoder). For high-volume public placements (storefronts, large-event signage), consider using a dedicated email alias that forwards to your real inbox, so you can disable the alias if it gets spammed without losing your primary address. For business-card scale use (you hand the card to specific people), the risk is minimal.
