The email validation API employs DNS and SMTP protocol functionalities to perform e-mail address validations without sending any email. This works by connecting to the recipient's mail server, and imitates sending a message. When the server gives a response that the appropriate email address is good or bad, the email verifier disconnects from the server and marks the email address accordingly. Thus it fakes SMTP dialog with that server, emulating a real mail server. This way it ensures that the server can handle emails for the address.

Very good. How long have you been running the service?

We have been in the email marketing business since 2009. But we launched this email validation API since 6 months ago. :)

Great, are you the developer?

We have our team of in-house developers who are developing the app.

The goal of this site is to give the developers a chance to talk about their project. It's not meant to be a place to market products.

Yes,I understand that. We are open to any discussion regarding the technology. Since this site allows commercial scripts or app, we deemed it wise to expose it here. The goal is not to commercialize it here but to expose the benefits of the app by way of the trial option that we offer. I hope this does not violate your TOS?

As long as you are involved with the development and open to suggestions that is fine. We just don't allow marketers to post apps they weren't even involved in building.
