Here are the results of an actual multivariate test I
ran in April 2006, for the salesetter at
http://AdwordsMaximizer.com
Type of test: An "L15" which is 2 options each of
7 different factors (variables).
Of the 7 factors tested, with and without the date at
the top of the salesletter was the factor that had
the least impact on response.
The winning option: Without a date, did 5% better than
with a date. Small margin.
That will vary by market and other factors, so by itself
doesn't prove that including the date is a mistake.

P.S. I posted this because of a debate I saw about this on
another forum.
