Does anyone else find these completely useless?

A couple of days before departure you get this text in bad English "we kindly remind about your upcoming travel". There is a unique link, but it doesn't open the booking, it just takes you to the Manage Booking page- so why is the link unique?
As the text doesn't mention any details of the flight, such destination, flight number/date & has no deep link to PNR, it is completely pointless.
