But SalesForce is messing with our space as they bought Jigsaw right when Jigsaw was talking with us. =(

Have you tried EmailTray (formerly SenderOK) which gets at least 10% the traffic on Alexa as xobni gets and just received an excellent review in PC World:

http://www.pcworld.com/article/212403/free_emailtray_helps_organize_your_inbox.html

Its a universal smart email sorter with social network profiles in the email header panes that will soon be a full client competing with Outlook (at least Outlook Express).

It shows the Facebook profile of senders, whose emails are divided into 4 priority Inboxes instead of just 1 Inbox (which was always a bad idea to have).

If you read and/or delete an email in EmailTray, it will be marked read and/or deleted back at its source, whether that is inside Outlook, AOL, Gmail, Yahoo or Hotmail. All the spam from all the webmail and Outlook spam folders will be accumulated in one big spam folder where everything can be checked and deleted all at once (meaning all spam folders will be emptied everywhere all at once). EmailTray’s smart algorithm would have already saved several good emails from the spam folder.

We’re going to be a full email client because Google and Microsoft and Yahoo were too busy looking at their navels or trying to invent half baked solutions for themselves on the fly, instead of answering our phone calls about how we could give them excellent smart sorting technology that actually works. =)

These guys are also working on updating their service and adding on a lot of features, plus they integrate with services like Rapportive, MailChimp, TungleMe and others to make it a full-feature service. Sometimes I wish I had a larger team, cause that would make it all even better.
