I'm using my Hotmail (yes I'm old, shut up) for my critical-to-life email communiques because I'm reasonably sure Microsoft won't randomly shit on me, unlike Google whom I'm always wary of even though I've had my Gmail for the better part of 2 decades now. For services that allow tying more than one email to, I've got one or the other as a backup/secondary so I won't be completely fucked one way or the other. As a general concern it's good to not have all your eggs in one basket anyway. If it's critical, have a backup plan and ideally a backup plan to the backup plan.
