Thank you for making the sync engine work client-side! It's a huge step towards making Nylas a viable choice for privacy sensitive folks like myself.
The next step would be to make features like "read receipts" that necessitate signing into a cloud optional. Being able to use the app without having to sign into a cloud platform would be a much more valuable feature for me than any feature such a cloud platform could enable.
Aside: as mentioned elsewhere in the thread, tracking pixel based read receipts in particular, is overwhelmingly only used in spam and newsletters and I personally consider it to be a liability rather than a feature.
Privacy concerns are very valid. You do have the option, however, of disabling those features in preferences, so you never have to use them (or the cloud platform) if you don't want to.
