How to create an email QR code
- 1
Add the address
Enter the email address that should receive the messages, for example support@yourshop.com.
- 2
Pre-fill the subject and message
Add a subject that says where the email came from, like “Feedback: Andheri store”, and an optional first line.
- 3
Download and test
Scan the code and make sure it opens your mail app with everything filled in.
How an email QR code works
The code contains a mailto: link with the address, subject and message. When someone scans it, their phone opens its default email app with a new message ready. They can edit it and then tap Send. The email comes from their own account, so you can reply directly.
Why pre-fill the subject?
The subject line works as a label. It tells you where each email came from and makes messages easy to filter and sort:
- “Feedback: Table 12” on a restaurant table card
- “Job application: Warehouse assistant” on a hiring poster
- “Warranty claim: Model X200” on product packaging
- “RSVP: Annual meet 2026” on an invitation
A short message such as “Name:” and “Phone:” on separate lines can guide people to include what you need. Keep it brief, because long text makes the code denser.
Good uses for email QR codes
- Customer feedback at shops, hotels, restaurants and clinics
- Support and warranty requests on packaging and manuals
- Job applications from posters, campus boards and recruitment stands
- Event RSVPs and registrations on invitations
- Lost-and-found tags on luggage, laptops and keys
- Quote requests on vans, site boards and trade-show stands
Things to keep in mind
- The address is visible to anyone who scans the code. On public prints, use a shared inbox such as support@ or hello@ rather than a personal address.
- An email app is needed. Most phones have one set up. If not, the phone asks which app to use. For anonymous feedback, a link to a web form in a URL QR code can work better.
- Emails aren’t counted. To know how many people scanned, use a dynamic QR code pointing to a contact page.
Set up your inbox to reply fast
People who scan expect a quick answer. Create a filter or label for each subject line you print, so messages from the shop counter or the warranty card land in the right folder. An automatic reply (“Thanks, we’ll respond within one working day”) reassures people that the message arrived.
Test it on more than one phone
Scan the code with an iPhone and an Android phone before printing. Check that the address is spelt correctly, the subject appears in full, and line breaks in the message look right. Then send the test email and confirm it arrives in the right inbox, not in spam. If your company uses a new domain, send a reply too, so you know answers reach people.
Print size and design
An email code with a subject and a short message is about as dense as a normal link code. Print it at least 2.5 cm wide on cards and 4 cm or more on posters. Add a label such as “Scan to email us” so people know what will happen, and print the address in text underneath for anyone who prefers to type it.
