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

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.

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!
