I would 1000% support an email digest add on.

Yes @robert, would it be possible to let the community know if and when we can expect the addon?

I have seen SO many forum posts and feature requests asking for this feature from many people, even year back with the oldest about 8 years ago. It would be popular feature as it is something that should be made available, weekly / daily digests to notify users of trending or new topics.

Posts I've found with such requests... and not a complete list
