Finally an end to all the mess. Archived 3500 E-Mails today and I relay like the conversation view. No manual needed, it is intuitive and great UI.

Why use PKG as trial installer? Weird.

I love the concept of this app, organizing mail based on contacts. It is intuitive, attractive, fast, low resource and the search feature works very well. It has now become my default mail client.

Great potential in this app. We would be interested in this mail client, if it supported pop accounts as well as imap accounts.

It advertises organization by contacts, but doesn't say if you can also go to a date received view. There seems to be a lot going for it, it has some really nice features. But limiting the Inbox view like that really is a turnoff. Also there is nothing about spam filters, yet again (and not just this app, it is just a nut Apple hasn't allowed us to crack yet).

And it would be nice to have a demo available. Even for $10.
