  • KLEAN13 Goes Way Beyond The Other Cleaning Services That Are Out There

  • I Trust KLEAN13 to Keep My Lists Clean

    Whether in the middle of a launch, or just regular day to day email marketing, it is CRITICAL to the success of your business to keep your email list clean to avoid possible blocking, blacklisting and penalties from mailbox providers like Gmail, Yahoo, Microsoft and others.

  • Thank You Klean13...You Saved Our Email Business!

    I've been a large volume mailer for over a decade. THE BIGGEST problem we've had with delivery is keeping our lists clean from spam traps and all the other "gotchas" in list hygiene. I've tested every list cleaning solution I could find. Every service I found left me without a real long term, infinitely-scalable solution. Klean13 has changed the game. It's a real solution that just works. It made my lists A LOT smaller than my ego wanted, but at least I know the lists I have now are clean and not an anchor on our inboxing. Thank you Klean13 for all you do. You saved our email business!

  • Klean13 finds all the things that other services don't...

    Klean13 has been the 'secret' list validation service I've used for my clients for years. It's amazing the things Klean13 finds things that other services don't. Whether it's an old list or a new list, Klean13 consistently highlights issues that need attention to get the best return.

    If your clients aren't getting your emails, what's the point? I've tried every single scrubbing solution in the industry and there is only ONE that I trust my clients lists to — that's  Klean13. I've sent dozens of my top paying clients to KLEAN13 over the past year with extraordinary results. Simple, professional and efficient — you've got a customer for life here!

  • KLEAN13 gave me a substantial Bounce Rate reduction and a 87% Open Rate improvement!

    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. ZeroBounce was great, EmailListVerify only 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!
