Email QR Code Generator
An email QR code opens a pre-filled email on the scanner’s phone, with your address in the To field and, if you choose, the subject line and message body already written. Businesses put them on business cards, flyers, packaging, storefront windows, and email signatures so a prospect can reach the inbox in one scan with zero typing.

What Is an Email QR Code?
An email QR code is a QR code that, when scanned, opens the phone’s default email app with a new message pre-addressed to you. It encodes a mailto link (the same mailto: format behind “email us” buttons on websites) so the scanner doesn’t type anything. At minimum it fills the recipient address; it can also pre-fill the subject line and the message body.
The scanner uses the native camera app on any modern phone (iOS 11+, Android 8+). No dedicated scanner app, no login. They point, tap the notification, and their email client (Gmail, Apple Mail, Outlook, whatever they use) opens with your address already in place. For a general primer on the format, see what a QR code is.
What a Scan Actually Does
When someone scans your email QR code, their phone opens a fresh email addressed to you. You decide how much is pre-filled.
Address only
The email opens with just your address in the To field, subject and body blank. Best when you want the sender to write freely: general contact, open-ended inquiries.
Address plus subject
The email opens with your address and a pre-set subject line like “Website inquiry” or “Trade show follow-up.” Useful for routing and for knowing which QR or campaign the message came from.
Address, subject, and body
The email opens fully pre-filled, including template text the sender can edit before sending. Useful for structured requests (support tickets, RSVPs, quote requests) where you want specific information back.
Getting the subject and body to pre-fill correctly is where many free generators fall short: a poorly built mailto link drops the subject or breaks the body on some email clients. Our generator encodes the full mailto string to spec, so spaces, line breaks, and punctuation survive across Gmail, Apple Mail, and Outlook.
Why Use an Email QR Code?
No typing an address on a phone
Reading an email address off a poster and typing it into a phone is error-prone and slow. One wrong character and the message bounces. A QR code puts your exact address in the To field with zero typing.
Subject lines tell you where leads came from
Set a different subject per placement (“From the trade show banner,” “From the product insert”) and your inbox tells you which channel drove each message. Free channel attribution with no tracking software.
Update the destination without reprinting
With a dynamic email QR code, change the destination address anytime from the dashboard while the printed code stays identical. Route to sales this quarter, support next quarter, without reprinting a single card.
Ways People Use Email QR Codes
Business cards and email signatures
Print an email QR on the back of a business card so a new contact reaches you without transcribing your address. Drop the same code into your email signature or a video-call background. Pairs naturally with a scannable contact card when you want to hand over full details.
Storefronts, flyers, and print ads
A window decal or flyer with “Scan to email us” lets passers-by start a message the moment they’re interested, instead of remembering an address for later (they won’t). Set the subject to the campaign name for instant attribution.
Product packaging and inserts
Put an email QR on packaging or a warranty insert so customers reach support with the product’s SKU or batch already in the pre-filled subject. See the packaging QR guide for the broader use case.
Trade shows and events
Booth banners with an email QR let attendees fire off a follow-up during the event, while interest is high. Pre-fill the subject with the event name so your post-show inbox sorts itself. Full toolkit in the event QR guide.
Lead capture and marketing campaigns
Each code’s pre-set subject becomes a campaign tag in your inbox: one code with “Spring flyer,” another with “Bus stop poster,” and inbound leads sort by source with no analytics platform. The marketing QR playbook covers attribution in depth.
Real estate, services, and support
Agents pre-fill the subject with the property address on yard signs, so buyer messages arrive labeled by listing. Support QRs on receipts route to the right queue. To collect public reviews instead, use a Google Review QR code.
Is There a Free Email QR Code Generator?
Yes, several free email QR generators exist, but the “free” label often hides limits that break real use. Free tiers commonly expire the code after 7 to 30 days (killing every printed card), inject watermarks or ads into a landing step, or cap scans at a few hundred. Some free tools also build the mailto link incorrectly, so the subject and body silently fail to pre-fill on certain email apps.
QRCodeStack offers a 3-day free trial with full features and no watermark. Static email QR codes cost $1 one-time and never expire, the most cost-effective option when your address is fixed. Dynamic email QR codes with editable destinations and scan analytics start at $5/month.
Static vs Dynamic Email QR Codes
Static email QR codes
Encode the mailto link directly into the pattern. They work forever, cost $1 one-time, and never need a subscription. The trade-off: the address, subject, and body are baked in at creation. To change any of them, you generate and reprint a new code. Static fits a permanent contact address.
Dynamic email QR codes
Encode a redirect that resolves to your mailto link. At $5/month with a 3-day trial, change the address, subject, or body anytime without reprinting, with scan analytics tracked through built-in QR code analytics. Dynamic pays for itself the first time you’d otherwise reprint a batch of cards.
Rule of thumb: printing on something cheap to redo (a weekly flyer)? Static is fine. Printing on something durable or expensive (business cards, packaging, permanent signage)? Dynamic saves the reprint.
Email QR Code vs Other Ways to Share Contact Info
vs a printed email address
The QR wins on accuracy and speed: no transcription, no typos, no bounced messages. Keep the printed address as a fallback for people who won’t scan, but the code is what most people will use.
vs a contact-form URL QR
The email QR is lower-friction for the sender (their own email app, drafts, and signature) but gives you less structure than a form with required fields. Email QR for a real conversation; a URL QR to a form when you need specific fields every time.
vs a vCard QR
Different intent. A vCard QR saves your full contact details to the scanner’s address book for later. An email QR starts a message right now. vCard for “remember me,” email QR for “message me.” Many cards carry both.
vs an SMS QR
Message length and formality. Email suits longer, formal, or attachment-bearing messages; SMS QR codes suit quick, casual texts. Plenty of campaigns offer both so the scanner picks their channel.
How to Create an Email QR Code
Step 1: Choose static or dynamic
Static for a permanent address at $1 one-time. Dynamic for an address, subject, or body you might change, or when you want scan analytics, from $5/month with a 3-day trial.
Step 2: Enter your email details
Enter the recipient address. Optionally add a subject line and body text to pre-fill. Preview the code, then test-scan with your own phone to confirm subject and body populate correctly before printing.
Step 3: Customize, download, share
Adjust colors, add a center logo, pick a corner style. Download as PNG or SVG. For high-volume runs (a unique support address per product line), the bulk QR generator takes a CSV and returns matched codes.
Print Size and Scan Reliability
Minimum print size for close-range scanning (business cards, product labels, inserts) is about 2 x 2 cm. For arm’s-length scans off flyers or table tents, aim for 2.5 x 2.5 cm. For distance scans (window decals, booth banners), the code should be roughly one-tenth of the scanning distance: a banner scanned from 2 meters needs a code around 20 cm square.
Leave a quiet zone around the code equal to at least four times the width of the smallest square in the pattern, keep high contrast (dark-on-light is the standard), and test-scan the printed proof under the lighting where it will actually be used. The QR code size guide covers distance-based sizing in detail.
Common Mistakes with Email QR Codes
Assuming pre-fill works on every device
Some free generators build the mailto link in a way that drops the subject or body on certain clients. Always test-scan on both an iPhone and an Android, and confirm the pre-filled text appears in the actual email app.
Static code for an address that will change
Bake a static email QR into a batch of business cards, then change your email provider, and every card is dead. If there’s any chance the address changes, use dynamic.
No caption telling people what the code does
A bare QR gets ignored. “Scan to email us” or “Scan for support” tells people what will happen and lifts scan rates. One line is enough.
Oversized pre-filled body text
A giant pre-filled body reads as spammy and gets deleted before it’s sent. Keep pre-fill short: a subject line and one or two prompting sentences. Let the sender write the rest.

Frequently Asked Questions
Can a QR code link to an email address?
Yes. An email QR code encodes a mailto link, so scanning it opens the phone’s email app with your address already in the To field. You can also pre-fill the subject line and message body so the sender only has to hit send.
How do I create a QR code for an email address?
Choose static or dynamic, enter your email address (and optionally a subject and body to pre-fill), customize the look, and download the code as PNG or SVG. Test-scan it with your own phone to confirm everything pre-fills correctly, then print or share it.
Can I pre-fill the subject line and message body?
Yes. Set the recipient address alone, add a pre-set subject line, or add both subject and body text. The sender can edit the pre-filled text before sending. Pre-filling the subject is a simple way to tag which QR code or campaign a message came from.
Does the person scanning need an app?
No. Every modern phone reads QR codes through the built-in camera app (iOS 11+, Android 8+). The scanner points the camera at the code, taps the banner, and their normal email app opens. No downloads on either side.
Where do I find my Outlook QR code?
This is a common mix-up. If you are searching for an “Outlook QR code,” you are likely looking for Microsoft’s built-in feature that lets you sign in to the Outlook mobile app by scanning a code shown in desktop Outlook. That is Microsoft’s login feature, not something you create here. This page is for generating your own email QR code that lets other people email you in one scan.
Can I change the email address after printing?
Only with a dynamic email QR code. Static codes lock the address, subject, and body at creation. Dynamic codes let you re-point to a new address anytime from the dashboard, and every printed code updates on the next scan.
How is an email QR different from an SMS QR?
Both open a communication app with pre-filled content. An email QR opens the email app with a pre-addressed message and optional subject and body. An SMS QR code opens the texting app with a pre-filled number and message. Email for longer or formal messages, SMS for quick texts.
Can I track how many people scan my email QR code?
Yes, with a dynamic email QR code: total scans, unique scans, time, location, and device type. Static codes do not include tracking because there is no redirect layer to log the scan.
Will an email QR code work internationally?
Yes. The QR pattern is a universal standard and the mailto link works with any email client worldwide. There are no regional restrictions on the code itself.
