You should rotate the areas that you mail too.

Whatever you could afford, rotate the marketing pieces to the same list.

Too me that seems like the lack of experience will result in some struggles which will put strain on your partnership unnecessarily.

When you said to rotate the type of letter you use do you mean that every person on your list should receive multiple types of letters?

I made 7 post cards that I will be sending out every 30 days in rotation.

But to believe that the 28th deal by Ashcroft is going to crash and burn, well, it strains credulity.

You don't want your recipients straining to see what it says.  

When I ran TV before I would run a rotating line up of two programming types.1) Jerry Springer type trash shows...2) Cable News Shows.

Most look at the .35 cents or so and think great price where in reality they shouldn't look at any number other than that of conversion rates, ROI and more importantly the cost of the infrastructure for the capture and fulfillment systems of the mail types.In short if I were only sending a few thousand pieces on a rotation I would send Yellow Letters followed by a Zip Letter/Check and then a postcard.
