How Email Verifier work?

Email Verifier uses SMTP for email verification. It starts with checking the email format, then the domain records (MX),
And finally, it connects to the target mail server and check whether the user really exist.

The validations are done in real-time and it may take around a second or two in general. Some SMTP servers may take more time to respond (above 3-4 seconds).

Disclaimer : Not all email servers co-operate in validation process (in fact, some are configured to do exactly opposite), so, it affects the accuracy of the api. However, in general, you can expect 90% or higher accuracy.
