How and What to Test Effectively

Most likely, you’ll want to test this same offer against outside prospect lists. You may find a particular offer works better when presented to prospects than to your own customers and/or vice versa.

When testing to outside rented names, it’s better to test those lists you know will work. Select a large enough sample to split into three equal test panels. A minimum of 30,000 names is needed if you’re going to split them into three groups of 10,000 each.
