Ah, that's actually a significant loss. It's quite useful to be able to search for when you signed up for X or Y years ago.
Most of the time you don't need it but when you do it's really valuable - e.g. I recently recovered some tiny at the time sums of crypto that were worth a few thousands now that way.
Yeah recently I had to replace the HID bulbs in my motorcycle. The Amazon ones were junk so I wanted the same ones I originally bought 11 years ago. Sure enough there was the email from 2010 and the company still had the same bulbs.
