    FastMail is great and is a good choice for many people. ProtonMail is most secure but it makes Proton not as user friendly. No bad choice, Proton most secure but not overly complicated to accomplish this. Tutanota is a happy medium. Fastmail is best for many. Doing something always better than nothing and Fastmail is happy medium many will stick with over getting tired of shortcomings of some others due to their privacy restrictions.
