====== Unsubscribe and Blacklist ====== Even though you are not sending emails yourself (it's done by the server script from that contact form), you still might want to use the following PHP-script on your website to collect domains of sites where you have sent a message but who are not interested. This would prevent any further problems and not send there again. Instructions are also in the script for further details.


 Edit Project ->Submission Content->Message add something like...

    Click the following link to unsubscribe: http://www.mywebsite.com/unsubscribe.php?d=%domain%
    
  3. in GSA Website Contact -> Options -> Global Filter -> add the URL to your $blacklist_filename from below
  
     http://www.mywebsite.com/blacklist.txt
