“Your draft is about to be deleted in 7 days”
You have an unpublished draft for a long time! Without any action on your part, the deletion of your draft will take place within 7 days from today.
if it’s a users draft and not the systems, it’d be better to inform him before deletion of his drafts using this setting:
delete drafts older than n days
this can be the case for cleaning inactive users as well, using this option
clean up inactive users after days .
