It is the analysis of different forms/versions of the one email to see which one performs best. Different forms are sent to a small part of the list or to the test group (if you have one) and the performance of each form is measured. Only one variable is changed in the email during one test to see what effect the modification has on the email performance. After test forms are sent to a little fragment of the list or to the test group, the best performing (winner) form of the email will be used for send to the rest of the list.
