Email QR Code
Free Email QR Code Generator — Prefilled Subject & Body
Encode a mailto: link — recipient, subject, and body all pre-filled — into a QR that opens the scanner's default mail app ready to send.
Quick answer
An email QR code encodes a mailto link with the recipient, subject, and body already filled so one scan opens the default mail app ready to send. To make one, enter the address, subject, and message, add your colors and logo, and download a PNG, SVG, or PDF. Free, no watermark.

About Email QR Codes
Email QRs ride the mailto: URI scheme — the same protocol that powers every "email us" link on every website since 1995. The QR encodes mailto:[email protected]?subject=...&body=... and the phone hands the URI to whichever mail app the user has set as default — Apple Mail on iPhone, Gmail on Android, Outlook on either, Spark, Proton Mail, anything. A compose window opens with the recipient, subject, and body all pre-filled. The user reviews and taps Send.
The value isn't saving the recipient from typing your address — it's the categorization the pre-filled subject enables. A QR labeled "Scan to report a defect" that pre-fills subject=Warranty Claim — Product Defect routes straight into the right ticket queue without a human triaging it. A "Scan to apply" QR on a recruiting flyer that pre-fills subject=Application — Frontend Engineer lands in the recruiter's inbox already labeled. The fewer fields the scanner has to fill, the higher the conversion.
EZQR generates email QRs free with no watermark, no signup, and no expiration. Static codes encode the mailto: URI directly into the pattern — they survive cancellation, work on every phone, and don't depend on any server we run.
Walkthrough
How to Create a Email QR Code
Set the recipient email address
Use a monitored business inbox —
support@,hello@,apply@— not a personal address. The QR is only useful if the inbox is checked. For high-volume use, route to a help-desk system (Zendesk, Help Scout, Front) that creates a ticket on receipt.Pre-fill the subject line for categorization
The subject is the single highest-leverage field.
subject=Support — Order #lands in the right help-desk queue;subject=Feedback — Table 7tells the floor manager which table sent it. Be specific enough to route the email without a human reading the body.Add a short body template (under 200 characters)
Pre-fill a body skeleton: "Hi team — I have a question about ___. My order number is ___." Gives the sender a starting point without locking them in. Long body templates create dense QRs that scan poorly — keep the body short.
Brand the code and download
Brand colors, logo in the center (under 20% area), high-contrast modules. PNG for digital, SVG for print at any size, PDF for the print shop. Minimum 2.5 cm on business cards, 4 cm on packaging, 8 cm on signage.
Test on iPhone and Android both
Scan from an iPhone (Apple Mail compose should open), then from an Android (Gmail compose). Confirm the recipient, subject, and body all populate correctly. URL-encoding bugs in the body field break silently — a 30-second test prevents a 5,000-piece reprint.
Where it works
Email QR Code Use Cases
Customer support QRs on product packaging — subject=Support: Product XYZ — Order # lands in the support queue with order context already in the subject, cutting first-response time in half.
Restaurant table tents for feedback collection — subject=Feedback — Table 12 tells the floor manager which table sent the complaint while the diner is still in the seat.
Hotel room cards for housekeeping requests — subject=Room 412 — Extra Towels routes to the housekeeping queue without front-desk triage.
Recruiting flyers at career fairs and university booths — subject=Application — Backend Intern 2026 lands in the recruiter's inbox already labeled, with the candidate's name from the body template.
Trade show booth cards routing to the right sales rep with a pre-filled subject — subject=Demo Request — Acme Corp skips the "let me forward this" round-trip.
Business cards with a "Scan to reach me" QR — pre-fills subject=Re: Met at <event> so context survives even if the recipient files the message a week later.
Real estate listing signs with subject=Showing Request — 1402 Ocean Ave letting prospects request a tour without typing the address or finding the right agent inbox.
Conference speaker handouts with subject=Follow-up — <Talk Title> letting attendees email the speaker for slides, references, or consulting follow-up.
Newsletter opt-in QRs on bookmark inserts and packaging stickers with subject=Subscribe — the subscriber just hits Send and the recipient adds them to the list.
Wedding RSVP cards with one QR per guest pre-filled with the guest name in the body — couples skip the manual "who responded" spreadsheet entirely.
What works in practice
Email QR Code Best Practices
Always use a monitored business inbox — support@, hello@. An unmonitored inbox wastes every printed flyer and erodes trust the moment the sender doesn't get a reply.
Pre-fill the subject line for routing. The subject is what triage systems and human first-responders read first; "Support Request" with no context routes worse than "Support — Order #1234".
Keep the body under 200 characters. Long pre-fills create dense QRs that scan poorly at small print sizes, and templates that feel pre-written get edited or deleted by the sender anyway.
URL-encode special characters in subject and body — spaces become %20, newlines become %0A, ampersands become %26. Reputable generators handle this automatically; verify by scanning the QR before scale-printing.
For high-volume support flows, route to a help-desk inbox (Zendesk, Help Scout, Front) that creates a ticket on receipt and auto-acknowledges the sender — turns the QR into a self-service support entry point.
Add a CTA: "Scan to email support", "Scan to apply", "Scan to RSVP". Naked QRs convert at half the rate of QRs with adjacent prompt copy that pre-frames the destination.
Print the email address in plain text below the QR — both as a fallback for failed scans and so phone-camera holdouts can copy-paste the address into their preferred client.
Use a dynamic QR ($5/mo Lite plan) if the destination inbox might change — staff rotation, team restructure, new help-desk vendor. The printed code stays; you repoint the destination from the dashboard.
Test on iPhone (Apple Mail), Android (Gmail), and at least one third-party client (Outlook or Spark) before scale-printing. Body-field URL encoding behaves subtly differently across mail apps.
Email QR Code FAQ
Common questions about generating, printing, and deploying these codes.
Does the email send automatically when someone scans?
No. The QR opens a pre-filled compose window — recipient, subject, and body are populated — but the sender reviews everything and taps Send manually. They can edit any field before sending, including the recipient. This is by design: a mailto: URI can only open a compose window; it can't send mail on its own. The browser security model and mobile OS both forbid silent mail sending from a URI.
Can I pre-fill the email body with a long template?
You can, technically — the QR spec supports up to 4,296 characters total. But long bodies create dense QR patterns that scan poorly at small print sizes, and body templates over ~300 characters look like marketing junk to the sender, who deletes them and starts fresh. Keep the body to a single short prompt: "Hi team — I have a question about ___." Give the sender structure, not a script.
Does it work with every email app?
The mailto: URI scheme is universal — it's defined in RFC 6068 and supported by Apple Mail, Gmail, Outlook, Spark, Proton Mail, Edison, Airmail, Fastmail, Hey, and every major mail client on every platform. The phone hands the URI to whichever app the user has set as default. The only failure mode is no mail app set as default at all, which prompts the OS to ask the user which app to use — a one-tap resolution.
Can I include attachments in the pre-filled email?
No. The mailto: spec explicitly forbids embedding attachments — a security guarantee, since otherwise a malicious QR could pre-load a phishing PDF the sender unknowingly attaches. If you need the recipient to send a file (a photo of a damaged product, a signed form, a screenshot), instruct them in the body: "Please attach a photo of the issue and tap Send." Most mail apps prompt attachment from the compose screen in one tap.
Will the QR work if the scanner doesn't have a mail app set up?
On iPhone, scanning a mailto: QR with no mail app configured opens Apple Mail and prompts the user to add an account first. On Android, the OS prompts the user to pick or install a mail app. Either way, the scan doesn't fail silently — the user gets a setup prompt. For audiences less likely to have mail configured (Gen Z, gaming-only Android users), pair the email QR with a URL QR to a web-form alternative.
Can I track how many people email from the QR?
Static email QRs don't track scans — the QR encodes the mailto: URI directly with no redirect. For scan analytics, use a dynamic QR ($5/mo Lite plan): the dashboard shows scan count, timestamp, device type, and city-level location for each scan. For email conversion tracking, add a hidden tracking parameter to the subject line (subject=Support — Order #1234 [ref=qr-2026-q1]) and pivot in your help-desk reporting.
Will the printed email QR keep working if I cancel EZQR?
Static email QRs encode the full mailto: URI directly into the pattern — no server lookup, no redirect, no dependency on EZQR running. Cancel, downgrade, close the account — every printed business card, packaging sticker, and table tent keeps opening the pre-filled compose window forever. Only dynamic codes ($5/mo Lite plan and up) need an active subscription for the redirect lookup.
