How to make a QR code that starts an email
A code that opens a blank email to you, with the subject already filled in, lets people contact you without typing an address.
It works on most phones, and it holds the information inside the code.
How do I make a QR code for an email address?
Use mailto: followed by your address, for example mailto:[email protected]. You can add a subject with ?subject=Hello and a body with &body=Hi. Spaces become %20. Paste it in the free generator, delete the https:// at the start, download, and test on your phone.
Will this get me spam?
The address is inside the code. Anyone who scans the picture sees it, and software that reads QR codes can collect it. Use a public contact address, not a personal one.
What is the better choice for print?
If the address might change, point a dynamic code at a contact page instead. You can swap the email later without reprinting.
