The first step in testing is getting organized. You’ll want to log your results so that you have ongoing record, notes, and analysis of your tests. I suggest setting up a simple spreadsheet grid like the one pictured below:
|Test||Email ID||Element Tested||Result Rate Click (%)|
|Version A||45678||25% off today only||47|
|Version B||54679||$10 off today||32|
In this case, it’s a simple matter of version A testing a “percent discount” versus version B testing a “dollars off” offer. The measure of initial success was the click-through rate. The email ID allows me to look up the actual email in my ESP software to review the elements and maintain consistency next time. I say “next time,” because I’ll use the winner as my control version the next time around and test a new version against it. Without record of your tests, you’ll mentally lose track at some point.
