As with Protonmail it would be nice if they could focus a little bit more on their core product. Importing emails is still not possible with them. As an email provider. With an open issue about it from 2018 🤷♂️.
They just change their subscription model a little while ago. Their new plans have much higher storage limits which is really good. It wasn't really needed when it was just email, but with cloud it'll definitely be useful. I'm very excited for this and I'll migrate from my legacy plan once this comes out! I have used them for 4 years now.
