You don't want your invoices or messages from other companies scanned so it is important to cut that connection. Friends and family or companies who use gmail they will have those messages. Those don't translate into products as easily. "Fun weekend with grandma say hi to sister" vs "purchased 3 day abortion pill from Walmart Pharmacy". You may want to protect those personal messages between family/friends but in reality the valuable (profitable) information is in the boring what products are you buying/looking at, what segments can we group you into.
