Hello,

sometimes I want to send newsletters to my customers. The problem is, that some of the emails get caught as spam messages. Mostly by Outlook at the client (even in my own Outlook 2007).

Now I want to know what should be done to create "good" emails. I know about reverse lookup etc., but what about a unsubscribe link with an unique ID does that increase a spam rating?

Regards,
Uwe
