Is the benefit of this over something like Protonmail or Tutanota the enterprise focus products? As an individual user seems like I may as well pocket the difference, right?
Skiff's free tier also has a 'generous' free tier with 4 aliases, 10GB of drive (only? combined with email?) storage, and custom domain support (? !)
Just that, it's one inbox in the Free tier. Since I'm using on my own domain, I prefer having one inbox for all addresses!
