How about those newsletters you're happy to read occasionally, but you don't want to interrupt you with notifications etc.?
I've got into the habit of marking all email with "unsubscribe" in it as read by default. I'll still see it when I open up my inbox, but it avoids me ever seeing a notification for something useless.
I'm not a gmail user, but if the following filter is available, I will move:
* Put all newsletters in a tab so I don't see them
* Delete all but the latest five unread of any particular subscription
* Delete anything older than 180 days -- even if I've read it, unless I've 'starred' it.
Can it do that? Coz that would absolutely kill for subscriptions. iTunes does that sort of thing for podcasts. How can newsletters be harder?
