For email provider Infomaniak provides as good of a service as google for free and their paid sub is 2 euros a month for 1TB of cloud storage. They’ve been a great alternative for me. Just need to find a calendar app you like if you want to use their calendar as it doesn’t have a mobile app.
Edit: Also I suggest getting your own domain and using that email instead so switching is easier in the future. You can set up gmail to infomaniak forwarding in Gmail settings (reply if you need help with it)
I got myself kualdir.eu for 9 euros a year and infomaniak handles the rest. Got 2 inboxes and can add aliases if I want to use those. Can always transfer the domain elsewhere if I want to switch and don’t have to worry about changing my email everywhere again.
I used ik.me before going to my own email and no issues with any site, its a valid email if they have issues with it honestly just take your business elsewhere cause if they can’t get an email validation figured out what else can’t they do well 😂
