There are several useful toolkits floating around that analyze webmail, and one of the most promising to emerge recently is the Graph Your Inbox Chrome Extension. To use this extension, you just install it, authorize it to access your mail data, run some Gmail queries, and let it take care of the rest. You can search for keywords like “pizza,” time values such as “2010,” or run more advanced queries such as “from:matthew@example.org” and “label:Strata”. It’s highly likely that this extension is only going to keep getting better, given that it’s new and has been so well received thus far. Figure 3-8 shows a sample screenshot.
