Dan and Ian have talked many times on this podcast about how the best ideas often come from scratching your own itch, or finding problems for solutions that you have experienced. Lately, Dan has had a very specific itch. Email tracking software has really been getting on Dan's nerves these days, so much so that he has even written a recent blog post about how much the industry is upsetting him. Enter Sonny Tulyaganov. Sonny was feeling some of the very same frustrations with email tracking software that Dan has been experiencing, but Sonny decided to do something about it. He developed a browser plugin called UglyMail, which allows you to see who is tracking your email. On this week's show, you'll hear the history of how Sonny developed this plugin, and the startling revelations about just how much of the information in your inbox is at risk.
