I also try not to use the default solo ad, and write the benefits and how the
product will help them solve their problem. What most people do when
they get 5 emails with the same subject is delete the message without even
knowing whats the product is all about!
But when a marketer has a really good relation with his list and he always writes the benefits and not just a copy-paste the default solo, the subscribers will definatelly read the message. This simply help the open rates and click throughs.
And that means more affiliate cheques! It is that simple!
