Looking for Newsletter / optin plugin

Hey to all..

I am looking for a newsletter plugin,
One that can collect email addresses, and send newsletters that include an unsubscribe link..

Single opt in is fine.. but I just need the unsubscribe thing.

In addition - what if I want to include a newsletter form inside a post... is this doable?


thanks.

GWA Autoresponder should do it... the full version is shared here in the download section

TY... will check.
