Where do people stand on the pre-email text. Not just the pre-header title, but also an unsubscribe link, view online and email to be added to the address book.

I'm taking another stab at our emails, and there's just so much text even before the email begins. So I'm taking a look around at what other emails out there have. A lot of them don't have the unsubscribe link at the top anymore and have even done away with the email address to be added to the address book.

Where do you stand on these details? I'm thinking of just having a pre-header title and a link to view online. Will taking out the unsub from the top (there will still be one at the bottom) and the sent email address have negative impacts?
