This is why I didn't and never will trust 3rd parties products/services getting accessed to my inbox and reading my emails wholesale in order to mine data or provide value. Paribus is another of such services that I am aware that require you open your inbox access to them (the pull model). There is nothing wrong with reading your emails with your explicit consent but I believe a push model like TripIt/Kayak's previous push model (send email receipts to trips@tripit/kayak.com) is a safer way to avoid privacy being violated and abused.
