Skiff Mail privacy-first, end-to-end encrypted product home, with Mail, Calendar, Pages, and Drive overview.
I have been using Skiff for about a year or so and was only satisfied with their email which can forward your Gmail emails and have aliases for free, the calendar app didn't notify me so it was useless but now it does and it works very well, I could also import my Tutanota calendar very easily. The drive has 10gb for free and can now download all your Google drive in one click and you can use IPFS as storage, this company is really making it easy to get out of Google with a smile.
Looks interesting. The first glance it looks like "Yet another company trying to make Email what it isn't", which means breaking all compatibility with existing mechanisms (e.g. IMAP) at cost of getting locked-in into their own ecosystem (unless you pay premium and enable IMAP back like Proton does).
This is why while I want companies like Proton and Tutanota succeed, I don't use their email products for business purposes.
