Moving away from GMail
Fastmail was my top choice, from a usability perspective and I read many good reviews of it. It ticks all the boxes, at a cost of 50$ per year. I evaluated it a year ago, but because the construction of my house started, I put the email migration project on hold.

    Hi, I have recently added a few exceptions to cookie auto-deletion, e.g. To ensure my email provider (fastmail.com) remains logged in. However, for other parties who I do not trust, such as Google, I don't want to remember cookies 99% of the time. Source: about 3 years ago

  • Chrome extension for managing your masked emails is now available!
    I too use a catchall address... And I'm always disappointed when Fastmail doesn't take all of the addresses that I get email sent to, and turn them into masked emails automatically! I guess masked emails are for people who dont have a custom domain and want to use their fastmail.com address, with some kind of email forwarding. Source: about 3 years ago
