What motivated the decision to give again the option to use Nylas for free? I remember reading that your target were kinds of "email power users", for whom you would offer the ability to create advanced workflow. Did this change?
The same happens for me with ProtonMail. I used the basic service but found that the convenience of a paid plan was enough for me to pay.
I was sort of put off by the look of Nylas though, in regards to the lack of a "native" feel. It was convenient, but I was forced into a paywall before I could really get acquainted as someone who isn't a power email user.
