dell email campaign before afterI just read this white paper about Dell’s email campaign optimization. The company tested factors like price, discount and subject line.

They found that “contrary to common marketing  knowledge,  test  results  revealed  that Financing, Price, and Discount were not influential. The most influential variables were Subject Line, Image,  Teaser,  and  Headline,  in  that  order.”

Here’s the white paper with photos of the ad before and after testing.
