E-Filtrate.com

My boss sent me a link to www.e-filtrate.com today & asked me to check it out. I have never heard of it before & their website kind of sucks, but their claim to assist in spam-proofing emails is intriguing. Has anyone ever heard of or used this service? If so, can it be used in conjunction with MailChimp? It sounds like a version of the MailChimp Inspection - only with suggestions included on alternative phrases to pass the spam filters. It sounds too good to be true, but I thought it was worth asking.
