I would tend to agree with the others on this post. When in doubt, offer quality content versus trying to offer a lot of bells and whistles.

For me, it usually came down to a good email autoresponder series, good banners, exit pop code (if you decide to), and a few other things (but these are the biggest).

If you do this, you should be good to go. Always remember you can add more as you go along.

And, it never hurts to keep your eye on other launches to see what they are offering.
