Mail Trends: Visual Analysis of Gmail
The Mail Trends program downloads the headers of all letters from the server, and then generates an HTML page with many interesting diagrams: here is the statistics of your mail traffic by year, month, day of the week and time of day; size of letters; the most active senders (with activity change chart) and much more.


Statistics are periodically updated by IMAP. It turns out a certain analogue of Search History Trends , but only for your personal mail.
To run Mail Trends, you must have Python installedas well as Cheetah templates .
