Does Vanilla offer a feature to email members daily of new posts that were made?
Yes and no.
Each member can set their notification preferences
https://open.vanillaforums.com/profile/preferences
If you are willing to take a risk and try out a work-in-porgress plugin check out https://github.com/R-J/DelayedNotifications
Never made it to the plugin directory because it wasn't sufficiently tested and other matters took priority...
