Can you elaborate on the limitations you experienced with fastmail and protonmail?
I have used Fastmail for years with a custom domain without a single problem. Amazingly great communications from the company too. Highly recommended but not free. (Less than $2/month though - so almost free.)
Then again, I rarely have and like having subscriptions these days because of minimalism but I suppose this is a good trade off for my entire lifetime.
On a different note, does anyone know how GoDaddy is in terms of privacy? Is there a better domain registrar out there?
Edit: Just realized I’m using Google’s Project Fi on my iPhone SE, with Hangouts.
