Yandex services are pretty nice (they have an equivalent to most Google things), but even more important for me is that - even on the lowest plan - you can talk to a real human in support within minutes, 24/7.
No, thanks. Google may be evil but moving my data from Google to the Russian government spooks is really not a solution.
Search is for sure hit or miss, but I pay for it and feel... a bit better.
For my "professional" email I use Amazon Workmail with a custom domain.
Of course there may be other reasons why you want professional email separate, such as not having it at risk should Apple decide you've broken their T&Cs because poor AI/ML says so, and they close your account.
It isn't really anything sensitive, really more just when I am interviewing and related activities.
But I also want it to be a separate email instead of just an alias which I assume iClouds is. Could be wrong though.
Amazon's is just $5 a month so not really a huge drive to change it.
