We are running our email tests through Litmus.....the greatest testing website on the planet. :-) Shameless plugs aside, we ran a test and got a 2.0 spam score.....All we did was change around the order of things in our email and now are getting a spam score of 4.0. Note, no additional alt tags, text or anything had been added. Literally all that was done was one table moving from one spot to another. Why would the spam score change so drastically?
