I have tried many email verification services, this is the best.

I've been a customer for a couple years now. I came to TheChecker from many other services. After getting too many complaints from lists, TheChecker cleared it all up for us.

Pros

The API is well documented, the results are the best in the industry. The pricing is great. But most importantly, I get far fewer bounces and complaints after running my lists through TheChecker than any other service. In the end, that's​ what matters most right?

Cons

There are no cons for me. It works great, it's​ easy to understand and its API documentation makes it very easy to get started. I can't find a thing to complain about.

The best email checker

Pros

The Checker is surprisingly good. The company is concerned with the custumers and always makes promotions for free credits. They value more the service than getting money at all cost. But about the software, It gives you not only the validation of the email but the risk of each email. I've never got a false positive with the checker.

Cons

You don't have a free limit to use it that is renewable per month. Only 10.000 credits for start.

Reasons for Switching to TheChecker

The older plataform had too many false positive emails.

TechAgency Feedback

We rate the quality of contact DBs

Pros

TheChecker API was very easy to implement and one of the cheapest email validation API on the market. Email statuses are broken-down into multiple categories allowing to precisely know the state of an email address and not just whether it is valid or not. In terms of performance the API responds quite fast even when validating several hundreds of emails in bulk mode.

Cons

One downside is that many email fall into the “unknown” category but this can probably not be avoided.

Excelente plataforma de validação de e-mails!

Tem sido uma ótima experiência utilizar o TheChecker! Está ajudando a melhorar a nossa performance e é extremamente fácil de usar! :) Recomendo demais!

Pros

A validação de e-mails é bem assertiva e rápida, ajudando muito a nossa equipe de vendas com a redução da taxa de bounce. Realmente tem me ajudado muito nas tarefas diárias de validação dos dados! :)

Cons

No início, a plataforma levava entre 5 e 10 minutos para validar um array de 10 e-mails, achei isso estranho, mas segui com o uso. Hoje, os mesmos 10 e-mails levam alguns segundos para terem sua análise totalmente concluída, o que me leva a crer que existe um mecanismo de machine learning por trás que é aprimorado a cada execução.
