So I occasionally get these marketing emails from Tesco. I’m sure I’ve tried to unsubscribe before, but they just keep coming. The “unsubscribe” link takes you to this page.
I can’t help thinking that there might be a teeny flaw in their system there.
Can you tell what it is?
[Clue: In case you haven’t got it yet, why not try typing (say) “email@example.com” into the box that says “Existing Customers Sign In Here”. He wasn’t previously receiving all their marketing emails, but he is now…]
