Not unlike many others, I use Thunderbird and sometimes think about switching to something else (main reasons are speed and usability). But I guess what many of us need much more than better email client is better email workflow. I have dozens of filters and always keep my inbox empty, and yet I think may be the real thing is I don't really manage my emails properly. Maybe I just need to set up this filter to delete stuff instead of moving it (I'm not really keen on deleting stuff in general, always feels unsafe and shortsighted), maybe I need some other system.<p>By the way, using Gmail web-interface (and Gmail is not the only mail provider I use) feels almost as unsatisfactory, as Thunderbird: ok, filters and search are a bit better, and it physically cannot hung-up my whole system under load, but otherwise it is as needy and clumsy as Thunderbird. I remember receiving several thousands of emails overnight because of some programmers mistake, and deleting it was quite painful: I'd gladly tell Gmail "just delete all this stuff" (by filter), but I didn't find any way to do so, I had to fall back to slowly manually deleting my mail by 200-item batches.<p>Would be interesting to hear how other people manage their mailboxes.
