Check whether a QR link is really an unsubscribe route
Some mailers include a QR code labeled as an unsubscribe or opt-out link. Before you scan it, confirm on the sender's official site that the destination belongs to the sender. A postal opt-out may also be available.
How to verify a QR code opt-out on a mailer
- Find the sender's official website from the mailer or an independent search, and look there for an opt-out or privacy page before you scan the code.
- If you do scan it, check that the address your phone opens matches the sender's verified domain before you enter personal information or confirm anything.
- If the domain does not match the sender's official site, stop. Contact the sender through a phone number or mailing address you verified separately.
- Ask the sender whether a postal opt-out exists, since a written request to a confirmed address does not require scanning anything.
What a scanned link can reveal
A QR code is a way to open an address; it does not authenticate the destination. Read the destination before entering information and compare it with the sender's verified website. If the domains differ, ask the sender whether it uses that opt-out provider. You can also ask for a postal preference route that does not require the code.
Use the paper route when in doubt
If you cannot confirm that the QR link belongs to the sender, write to the sender's verified postal address and include your mailing label details. The guide at the comparison of postal opt-out options covers routes for when a digital opt-out is unclear.
