Is the "open source" label still comically misleading? [0] I tried it out, didn't read the fine print, filed an issue, never looked at it again. Because "It keeps user data local and private." is kind of one of the main benefits. [0]: https://github.com/nylas/nylas-mail/issues/860
Ahh thanks I need to update that! Originally Nylas Mail was OSS, but tied to the Nylas Cloud APIs (which did the actual mail processing.) The cloud strategy was too expensive, and in version 2.0 the entire mail-sync system was moved into the client and open sourced. ( https://github.com/nylas/nylas-mail/tree/master/packages/cli... ). It's now much more like Thunderbird. There's a bit of cloud processing for snoozing…
If not (yet), would it at least be technically feasible, and would supporting this be an option for you?
