For a private email address the pricing does indeed seem quite steep.

For a business email system it seems to miss a few features, especially around meetings.

Email seems to be warming to innovation again, but an approach that doesn't go for rip and replace, but rather augments and extends these features into existing email clients might have its benefits? e.g. Yablo [1] extends Outlook with a team collaboration and productivity environment, but it is still the full Outlook client and email to the outside world, so existing workflows and integrations built around that aren't disrupted.
