Check a segment against the Global Suppression List

Learn how to compare and revise your segments against the global suppression list.


The Global Suppression List (GSL) is a collection of known bad email addresses and domains, including ISP spam complainants.

You can use the GSL to revise your entire contact list by comparing your list of contacts against it. We'll automatically remove any problematic addresses known to us, cutting down on the number of complaints you might otherwise receive. This does not clean all problems from your list. A good list acquisition is still key.
