very strange. this does not happen on my emails about the daily digest. I googled "nolo" and there is a company called nolo. It's mission statement: "Our mission is to help consumers and small businesses find answers to their everyday legal and business questions." It appears to be all online stuff.
The interesting thing is that it is a wholly owned subsidiary of "Internet Brands" which is the same company that owns the QB. (You see that at the bottom of every page). Did you by any chance purchase something from Nolo? I'm wondering if they connected the dots and recognize you from that, and have "personalized" your daily digest emails.
