Totally this. Maybe a great email client doesn't need to be a SPA. I love a lot of the decisions HEY made, and think the onboarding was lovely. But I think people are over hyping the core UI/UX. Is it fast? Yes. But what data are they really loading? It is also clunky and has obvious design decisions that seem made to get around needing to use more JavaScript.
I will be very interested to see it after a year of polish however.
