Indigo Moon Systems mentions us along with some other easy business tools. I like his description of Sproutit Mailroom:

I just came across this one-it’s not free, but it’s interesting and I have at least one current client I’m going to recommend it to. It’s an online automated e-mail management system, using basic artificial intelligence to receive and sort mail coming in to common addresses (like “sales” or “support”) and automatically produce recommended replies, reducing the time to manage each individual piece of mail. This has long been a function available in helpdesk software, but that’s either very expensive or very complicated to implement-this is entirely web-based, easy to get started with, easy to quit if it doesn’t work well.
