I get way way too many emails as is is from Workfront, but as the system admin it can be a necessary email by choice to receive them.
Did anyone else suddenly start receiving 'Digest' emails this morning unexpectedly?
I most certainly have no desire to get a digest of 'Work Assigned to You'.....ever.
