We do not use your email for announcements, and trying to reduce the spam from us to a required minimum like notifications when your node goes offline and returns online.
I do not think that there something regarding changing of the communications channel in the roadmap. There is also a problem with mass email relays - most will add satellites or address which we could use as a spammer and we cannot communicate important things to our customers. So, I would not expect that something would change here.
So, I can only suggest to subscribe to the forum.
