A QR Code in Your Signature — Done Right
A QR code in an email signature sounds odd at first: the recipient is already on a device, so why scan anything? It makes sense in one specific situation, which happens more than you would think — someone reading your email on a laptop who wants your details on their phone.
It is genuinely useful for that, and for printed emails, screenshots and shared slides. But there is a catch most guides skip, so let us deal with it first.

Why It Works
Laptop to phone in one scan
Your details jump from the screen they are reading to the phone they will actually call you from.
Survives screenshots
When your email gets screenshotted and forwarded, the code still works — a mailto: link does not.
Books the call directly
Point it at your booking page and "let's find a time" becomes one scan instead of four emails.
Useful when printed
Emails still get printed for meetings. The code is the only part of your signature that survives on paper.
How to Set It Up
- 1
Choose what it should do: save your contact details (vCard tab above) or open a booking page (URL tab).
- 2
Generate it and keep the image small — 100×100 pixels is plenty, and a heavy signature image gets your mail flagged.
- 3
Add a text line next to it saying what it does; if images are blocked, that line is all the recipient will see.
- 4
Always keep your name, role, phone and email as plain text too. The code is an addition to your signature, never a replacement for it.
Frequently Asked Questions
What is the catch with images in email signatures?
Many mail clients block images by default, and some strip them from replies. Your QR code may simply not appear. That is why the details must exist as text as well — a signature that is only a code is invisible to a large share of recipients.
vCard or a link to my website?
vCard if you want to be saved as a contact; a link if you want them to do something specific, like booking a call. Do not try both in one code — pick the action you actually want.
How big should the code be?
Around 100×100 pixels on screen. Smaller and phones struggle; larger and your signature starts to dominate the email. Keep the contact details in the code short, so the pattern stays coarse enough to scan at that size.
