I have a gmail account I've used with clients over three years. Around 6,000 messages inside. Is there any application I can use to do some datamining on all this? Something that can take in all these messages and extract the obvious things, email addresses, phone numbers, dates, number of replies, etc. And, the less obvious things: times sent, geographic locations, pictures from users, social media links, and other items that can help me to discern patterns in this tranche of information.
