Hi @janetb. Your email frequency shouldn't have changed. That's odd. When I look at your Preferences, it looks to me like you are still set to receive emails just daily and not for every post. Do you think maybe you got just a few individual emails because someone was replying directly to you or mentioning you directly by username in a post? The software is set to do that by default. I think you can turn that feature off in your Preferences.
I think also, some semantics were getting confused above.
This forum software we use (Discourse) has a setting they call Mailing list mode which allows you to get an email for every post or just a daily summary.
(@seth-ganoksin-admin, you may be thinking that Mailing list mode is the "reply by email" feature? That's a separate setting which is not called Mailing list mode.)
If you don't have Mailing list mode on, then you can choose to get an Activity Summary email every once in a while (you pick the frequency) when you haven't visited the site in a while.
Hope this helps! So many settings ... it gets confusing! And hopefully I didn't misspeak above!
