Advice for using BookFunnel

I’ve had a short story as a reader magnet on BookFunnel now for about a year and I am getting ready to replace it with a new one. I’d like my current newsletter readers to have the new short story, but I’ll also be using it as a magnet for new subscribers.

There are several choices for a landing page on BookFunnel. Any advice on how best to set this up?

1. Use the BookFunnel landing page and require the email address to get the new short story.

2. Make them sign up first, and use a Restricted Landing Page where they have to enter their email address again.

3. Or use #1 for new subscribers so they sign up once and get added to my newsletter list, but use a simple landing page for current subscribers and give them the direct link.

Experiences, or pros and cons to share?

Thanks!
