First is Google, who we use for company email. This means any interaction with our customer support team has emails stored with Google.
If you self-host everything else, why don't you do the same thing for emails as well?

You don't sell anything directly, but they can and probably are sharing all email content with government agencies.
As always, when buying a hardware wallet, we recommend providing as little personal information as possible. As an American company we may be required to comply with law enforcement requests (though we'd fight any request as hard as possible).

I think this is a best way for reducing digital footprint and there is no risk of any leaks happening in future.
