I signed up for this free CRM that integrates with Gmail more than a month ago, but hadn't had the time to actually figure out how it worked. I went to one of their how-to webinars, and that helped a bit, but still wasn't quite sure how to use it for myself. I finally had some time to play with it and I am SO glad I did!! I created "boxes" for every contact I have had and then with a few clicks, I can link all of the emails related to that person so that I can see them in one place. I can categorize contacts however I want and I can easily see the date of last correspondence. This tool is awesome!! I highly recommend checking it out- after all, it's free!
