You Will Get Nowhere By Doing What Everybody Else Is Doing.

Here is a simple and quick answer, but value is not determined by the number of words.

What you need is a segment your list. Do tests with links, keywords, and offers when you send out emails. In say, 5,000 emails you use a link that will make an offer for more info, newsletter, product, services, etc. Anybody who opts into this new list are then further segmented and can be marketed to in a certain way. They never know that they are segmented, but you do.

It allows you to have a powerful way of marketing. One size doe not fit all.

Good Luck,
