I couldn’t find more recent discussion of this…
I would also find a report & tracking of atomic unsubscribes interesting.
I do have the Data Explorer query to list digest-unsubscribed users. But:
- Dates aren’t recorded, so it’s hard to spot a trend.
- Sometimes I’d like an idea of whether they’re new or old users, how active/inactive they’ve been, whether they’ve also requested no emails whatsoever, etc.
