Nice bit of data (and a link to a script) that shows roughly how much of this person’s email ended up on a Google server at some point.
For almost 15 years, I have run my own email server which I use for all of my non-work correspondence. I do so to keep autonomy, control, and privacy over my email and so that no big company has copies of all of my personal email.
Since our conversation, I have often wondered just how much of my email Google really has. This weekend, I wrote a small program to go through all the email I have kept in my personal inbox since April 2004 (when GMail was started) to find out.
From eyeballing the graph, the answer to seems to be that, although it varies, about a third of the email in my inbox comes from Google!
I’ve run my own email sever for many years as well, for some of the same reasons, and it’s a little disappointing to consider that it really doesn’t make a whole lot of difference.
