No. Yolo. (Also, in the past 20 years I never needed to find any personal email that's older than a week, so I'm not terribly concerned about the effect of dataloss.)
I would have agreed with you until this year where a single email from 18 years ago, which I didn’t think anything about at the time, is saving me from being sued. It doesn’t matter until it does. I got lucky.
If it's possible to give any detail without giving too much, I'm curious what the nature of the situation was and what the saving document was?
