I really like the simplicity of this tool and it's perfect their registration process so easy, API helped me to integrate the email validation directly inside of my website, so I don't waste time looking for any email verifiers. Great tool!

It's a perfect solution for validating the email list. This service has helped me to increase conversion to 78%. I'm satisfied to work with them, almost 5 months use it. Good job, guys!

Probably one of the most comfortable validation services, simple in use.
