hmm - maybe you would get better results if you did send irregular messages to your affiliates inspiring them.
Maybe sending them a success story of how some one else earned a good profit being your affiliate would give them the nudge they need to focus on selling your products.
In my experience - I have found that the first sale is the deciding factor. If the affiliate gets commission from his first sale within a week or so - he focuses more on selling the product. He has seen some results - and so he is all set to roll.
And in my experience - a few inspiring messages with case studies - would help the affiliate to get the first sale faster - and make him more determined in selling your products.
But I have never tested this - and don't know for sure if sending inspirational case studies does increase the results of the affiliates. But its worth testing.
