I'm sure lots of people have this, in fact i think Google actually implements this in native (on the web) Gmail, but I'd prefer it to be under my control.
1) When i get an email newsletter, sometimes it makes all previous newsletters from the same sender obsolete so they all need deleting (and sometimes it doesn't).
2) when i get an email with the complete thread of the conversation still in it, i no longer need the previous emails
Can Kutools produce a button so i can select a particular email, and either "delete all previous (but not this) from same sender" or "delete all previous (but not this) with same subject (taking into account the usual conversational prefixes)?
You may tell me it's already there - sorry but i haven't seen it in the description of tools
