Google’s Gmail scans, parses, analyzes and catalogs your email

I still couldn’t believe that Google was in essence reading your email and cataloging your purchases on it’s own. And so we click to find out…

We get it from Google’s mouth:

“This purchase was found in your Gmail” (emphasis added, because properly rendered it should read “We found this financial transaction sifting through your email”). If you have lots of historical email at Gmail (or anyplace else) you can use our IMAP migration tool to painlessly copy everything over from Google, except, alas, your purchase history.
