Hi Paul,

There is a bit of a healthy mix here...

There are certainly plenty of offers that won't convert.

Me mailing a "how to play the piano" offer with an expensive price tag and a weak pitch to a group of truck drivers may land me a sale or 2 if I mail 5, 7, 10 times... but it's a poor conversion.

But, if you know the offer is relevant and the pitch is quality and see a few sales come in from the first mailing... then most of your list needs to be "interrupted" with that SAME offer a few more times to really have the value of it set in before they buy.

Conversely, if you interrupt them with a different offer again and again and again, you lose credibility and they won't understand the value of any of them. Only your super eager hyper responsivess (hint: your minority!) will buy.
