There are only two IP-based reputation services that are truly widely used, world-wide, ours and Validity's (nee 
ReturnPath).  

Our have *always* been free for receivers to query, and always will be, as our primary reason for having been in 
business for going on 20 years is to provide a way for *receivers* to determine the ham from the spam (making it easier 
for them to reject spam).  I'm surprised to hear that *any* of the others are charging for access for querying - 
shocked in fact.

 You can always query our IADB (ISIPP Accreditation Database, now known to consumers as the Good Senders List, or GSL) 
here:

iadb.isipp.com

More general information about the IADB is here:

You can read more about our granular query responses, which we call Data Response Codes (we were the first to develop 
this method of responding to IP-based queries, nearly 20 years ago):

If you have any questions, any at all, please feel free to reach out to me directly.

Kind regards,

Anne
