Glad to talk to you today about optimizing notifications on the community. When you submit an idea or share a comment on a thread, you should receive notification emails instantly when someone replies or there are updates. That's in addition to the Community Digests that you receive. For all users, the details on which emails you will and won't receive are fully customizable, just click the carrot next to your avatar in the top right corner of the community, and Click Preferences in the drop-down menu. There you can decide exactly which emails you should receive, and with what frequency.
Rachel Hudson, one of those you showed me was when someone @mentions you in a post, which I just did.
Please reply in this thread, did you see the notification?
