  6. Attach a domain

    Optionally, we strongly recommend you attach a domain to Linkly.

    This makes QR codes more reliable, and fixes almost all scanning issues.

    As an additional bonus, QR codes remain on your domain, rather than ours, meaning if you decide to leave Linkly, you can take your QR codes with you.

Frequently Asked Questions

Can I change the mailto after the QR code is made/printed?

Yes, you can edit the mailto, and the QR code, even though it's printed, will now use the updated mailto.

Why does my QR code scans on some phones but not others?

It is likely your QR code is being blocked by a content filter.

Attach a domain - this solves almost all issues.

Why does my mailto link not open?

The limit is usually under 10 lines.

Will I be able to track the number of scans?
