What is your threat model? What adversaries are you fighting against?
My adversaries are corporations. I don't want Google or Microsoft to know every service I register to, every bill I receive, my income, all my contacts, all my pictures. Fastmail works perfectly fine for this (up to the point where you contact someone who uses Google or Microsoft emails, etc...) and it's perfectly fine for them to advertise themselves as privacy focused.
Is your adversary the government? Unless you're a journalist or dissident you aren't doing what's necessary to protect yourself from the government anyway. Of course security isn't black and white so if you can have a secure-against-the-gov email provider that's good but let's be realistic the government is already recording all of your communications and has much easier access points to your confidential data than your email.
