First, let’s be clear about the distinction between sales and marketing roles: you wouldn’t believe how many companies scramble the definitions. As a card-carrying marketing guy (yes, I made it to Sr. VP at publicly-traded companies), I maintain that the outbound part of marketing (the real users of marketing automation) needs to focus on getting the right message out to the right prospects. People who respond with the right level of interest are handed off to sales for qualification, and people who don’t are kept in the system for cultivation and “re-marketing.” Outbound marketing is also involved in the care and feeding of existing customers, to cultivate loyalty and repeat business.
When you start your day at work, you likely open a half-dozen apps and websites and spend quite a bit of time just figuring out what needs done and finding the info to do it. Not anymore with Infusionsoft. It's watching your site, tracking info about your potential customers and what they've seen, and at the same time is keeping up with what you need to do. Then, in a nifty "My Day" view, it'll show you everything you need to be doing—including your tasks, communications with contacts, and calendar appointments—along with info about the customers related to your tasks right in the same overview.
Contact-focused CRMs are one of the best ways to maintain a personal touch with your customers and business contacts, since you'll have one place to keep track of everything about them. Hatchbuck gives you that same contact-focused interface combined with even more detail about each person related to your company. It has a bit more focus on the traditional ways you'd gather leads—especially via forms—than the other apps listed here, and instead of focusing on every possible visitor it's just focused on the important leads you import or that fill out your forms.
