Thanks a lot!
Ótima ferramenta! Melhor que já usei até o momento. Única que achei que valia a pena o investimento para seguir usando.

Obrigado! :)
Really useful. I got a deal on Appsumo exactly when I needed to perform some list higiene. It worked perfectly! I don't do email validations very often so I love the fact that they have a credit system and not a subscription sistem.

Slick product

I love, love, love the ease of use for importing large lists and how quickly the results were returned. Highly recommend this for all.

Love this! Super simple integration and works as advertised. Bought The Checker through the AppSumo deal a while ago and after one test run to see how well it cleaned the addresses I stacked as many codes as I could. It's that good!

Awesome! Thanks!
Love TheChecker. Looking forward to trying this out!
