I’ve thinking about purchasing Proton Mail Plus only and just only to have IMAP support, but I’ve looked all the features that the Proton Unlimited Plan have, and honestly I believe it’s worth, but I hate having all the eggs in the same basket.
The features I believe worth the most are the 500GB storage, IMAP support, all the VPN servers with P2P and unlimited SimpleLogin aliases, but when I ask if it is worth the price I mean, the majority of those features I can have them having individually with others services and even at lower price.
Self hosting email is a huge PITA. That’s one service you better pay for.
This guy who has been hosting his own email for 23 years and gave up agrees.
