Lookup, Verify and Check Email Address With Email Checker For Free
Email lookup, also known as either Email checker or Email verifier, is very fast, highly accurate and free email service from IP-Tracker.org which provide live verification process of all emails using next steps:
- First, Email lookup resolve host name (SMTP server) to IP address
from Email that you are checking and then try to connect to that SMTP server via port 25 (it is standart Simple Mail Transfer Protocol port for sending mails).
For example email@example.com point to Email SMTP server mx4.hotmail.com with IP address 18.104.22.168. If connection is successful then our Email checker tool start to check Email using verifying process.
- The process of verifying email is done by sending SMTP HELLO command
to other side (SMTP server) asking to verify email address.
Once SMTP server accept our request and our "question" then he let us know of Mail ID / Recipient is OK or NOT.
- Final step of our email lookup process is to let you show answer from SMTP server after
the process of verification and checking has been done:
"the host states that the address is valid or not."
Once we get answer we disconnect from SMTP server.
