"Rita, I've read Frank's and many others and none of them come right out and say what the magic is to put in your email.
Yes Frank puts out good info but to me they all stop short of what to put in the email. "
Good point Jeff.
What you're doing with email campaign, as Jeff suggested, is you're selling the click ... on the email and then on the link.
You don't make the hard sell, rather you share your stuff, your story, and post your call to action ... the click.
It doesn't matter how many or how little number of subscribers you have, as long as they are quality and they click open your mails.
For example, I have several lists of a few thousand combined, and a subscriber open rate of 62% and a click on the link rate of 12%. When I had 200 subscribers it was a lot lower open rate, but once you grow it then you have more that don't respond. So you have to keep cleaning the dead subscribers so that your list is clean and sends better. My lists mostly grew by my present subscribers sharing my mails with others they know. So even if you don't have the link click rate, you could have a higher forward rate. So you work on your subject line more than the content of the email, to get the email click open rate.
With email, the subscriber has two options: Click open. Delete. But they always see the subject line to make that decision.
Hope this helps.
