I moved one of my domains over to ProtonMail. I’m still very happy with Fastmail but wanted an alternative/backup email provider. I’ve used Proton occasionally and figured this would be a good way to start using it more.
@jmreekes I’m very curious to hear your thoughts. I’ve been using Fastmail for years, but am preparing to transition to a new primary email address. I might take this as an opportunity to switch email hosts and Protonmail would be high on my list of contenders.
