ZeroBounce vs. Klean13.com

Klean13 or ZeroBounce – which one should you choose? The two email checkers seem similar at first glance, but there are a few important differences between them.

Let’s start with the price: $97 to validate 10,000 email addresses with Klean13 versus $80 to clean the same number of contacts with ZeroBounce.

We wondered if Klean13 offers access to more features since its prices are higher. Not the case.

For instance, the company doesn’t disclose whether it removes duplicate contacts for free. Also, there’s no mention of abuse emails detection – emails that ZeroBounce isolates. They belong to serial complainers, so if you want to avoid the risk of spam complaints, ZeroBounce gives you the option to remove them from your list.

Furthermore, Klean13 does not append any data to your email list, like ZeroBounce does.

One thing the two email verifiers have in common is that they both detect disposable and catch-all email addresses.

Klean13 does not state how accurate its email validator is and does not have a money-back guarantee. As for support, at ZeroBounce, you can connect with a live person within seconds, which is not the case with Klean13. The company’s representatives respond only during normal working hours.
