I finally got a chance to test out Paranoid Android's Email cleaning service and I must say I'm impressed. I submitted a list of 1,000 Emails to PA's service for my test. Four hundred (40%) of the Emails were from lists of old spam trap and SpamCop reporter addresses I collected in 2008 and 2010. Six hundred (60%) of the Emails were from a Casino list and a Stock Investors list, both from 2010. Also mixed into the batch of 60% percent of the Emails was a list from an unknown source I cannot remember, also from 2010.
Out of 1,000 Emails, 475 came back as clean and I have included an image of the graph below.
As you can see, it only removed three spam traps. First of all, my lists of spam traps and reporters (not to mention my lists in general) are around seven years old so a lot of the spam traps and reporters could be invalid by now. Secondly, no Email cleaning service can guarantee that they will be able to remove all spam traps. I would be more concerned about this if I had submitted a list containing recent spam traps and reporters.
Spam traps aside, the service worked exactly as it was supposed to work. I love the fact that this service has ten different Email statuses that it uses to clean your lists (refer to the graph above), not to mention it is fast, easy to use, and very effective.
In conclusion, I am very satisfied with the results of my test and as others have already stated, there is no better person to deal with other than Paranoid Android when it comes to Email marketing. When I need some of my lists cleaned in the future, this is the service I will use. I would also recommend it to anyone who has lists they need cleaned by a reputable service.
