I would hate to lose my emails for several reasons.
We have projects that go on for a long time (one of my current projects started in 2019), and I would hate to lose that project correspondence automatically.
I sometimes go back through really old emails to find something that I remember corresponding about years ago but have no idea which project it would have been for.
It makes me uneasy for the only record of correspondence to be in someone else's hands. Unethical as it is, someone can edit text you write in email chains, delete the original, and now it looks like you said something you never said. I think it is beneficial to have that original in your "sent" folder in the event that something becomes a legal dispute. I have thankfully never been involved in litigation, but I think it is best to have control over your own information.
I'm curious if others are experiencing this trend of not retaining emails, and I'm also curious what the motivation is. Is it not wanting to pay for the storage? Is it the (in my opinion false, if you're acting ethically) idea that keeping the records opens you up to them finding things you don't want them to find?
