OathQR

Free forever · no account · no watermark

One scan opens a ready-to-send email.

Address, subject and message already filled in, so the person scanning only has to press send. Works well for feedback requests, booking enquiries, support labels on equipment, and 'email us' posters that people actually use.

This code is pure data. It carries your content directly instead of a link through our servers, so it can't expire and we couldn't turn it off if we wanted to.

I.

It cannot expire

Static codes are pure data. There is no timer, no scan limit and no trial, so there is nothing that can run out.

II.

It never touches our servers

The code is generated in your browser. We never see your content, so we have nothing to hold hostage.

Download PNG, SVG or print-ready PDF and use it commercially, without signing anything.

Lower the effort, get more replies

Nobody transcribes an email address from a poster. With a code that opens a pre-written draft, the whole interaction is scan, then send. Put the question in the subject line and a skeleton answer in the body, and you will get replies from people who would never have typed a word.

Private by construction

The mailto: link is assembled in your browser and encoded straight into the image. We never see the address you put in, and the person scanning writes to you directly, with no intermediary that could go out of business or start charging rent on your own mailbox.

Questions, answered plainly

How does an email QR code work?
It encodes a standard mailto: link. When scanned, the phone opens its mail app with the address, subject and body already filled in. It uses the scanner's own email account, and nothing passes through us.
Does it expire or have a scan limit?
No. Like all static codes on this site, the data lives inside the image. It keeps working as long as the email address exists.
Can I pre-fill the message?
Yes, both subject and body. A prepared draft lowers the effort to almost zero, which is why feedback and review requests convert much better this way.
What if the person has no mail app configured?
The phone will ask them to set one up or offer web mail. Practically every smartphone in use handles mailto: links out of the box.
Where do email codes work best?
Feedback cards at checkout, 'report a fault' stickers on machines and lockers, event posters, and packaging inserts asking for a review.
