Your e-mail will never be sold..

" your e-mail will never be sold or rented."

what's not said is :

"but I will send you a mail every week just so you remember me"
"but I will send you advertisements about each new book I write"
"but I will send you polls to find out what products you like"
"but I will send you references to other autors who might ask for your e-mail so that they can do the same"

"but your e-mail will never be sold or rented.. just given to others! who in turn give me lists of people who's e-mails will never be sold or rented"
