I just wanted to post some results I've had and give a testimonial to the cleaning platform KLEAN13
I had used emaillistverify.com and zerobounce.com previous to this to do my cleaning. Both were ok but recently I ran a test with Klean13 and had even better results: 

A substantial Bounce Rate reduction and an 87% Open Rate improvement! Thats going to change my bottom line! Thanks KLEAN13!
