make your own .much more profit..
ill tell you how in 3 easy steps..
#1 go copy the basic layout of a free email type program ( i.e. make a page with a form and a box to enter email and password etc )
#2 setup phpbb ( its free ) load it with fhg'd , go to the "register" page and look at the html for the signup form, cut the items out you want to display on your free email box ( i.e. name and email and password ) point your email box to the phpbb register form
#3 use the "mass email " function in phpbb to email your clients ( surfers )
p.s. you owe me $100 if you use this idea
