Someone in jail for a two year stint that ends in December may be emerging to find the email they had for twenty years, which may be the key to most of their other accounts, is gone, which could be hugely impactful.
In my personal life, I do now have the unfortunate task of reminding people to log into dead relative's email accounts so they can preserve some shit they need, which kind of sucks.
Email is a bit different to me than like cloud storage, because so much gets tied there -- social media, banking, etc., that I don't like the idea of gambling with it unless I'm sure an account is a throwaway. People incarcerated, hospitalized or dead may not be able to regularly access their email, yet the information inside may be vital to them and their family.
Ghoulish, but as I mentioned earlier, now I have to remind people to be sure to log into their dead relative's email accounts to preserve information.
