@denisl, I thought that for a long time too, but seeing the ratio stick when I send a newsletter that goes to 250K+ active users; really throws me for a loop.
Why do I get 40% more Google referrals during the 48 hours that my newsletter is going out? This is regardless of the day/time (Sun, Tues, or Fri) it's sent. The only thing that goes up by 40% at that time is direct traffic.
