Cleveland, OH -- (SBWire) -- 11/23/2015 --Capturing good leads entails the verification of email address information exactly at the point of entry. For businesses who run online, it is imperative to have a clean mailing list.

Knowing that email address verification is not as easy as it seems. Commonly asked questions such as how do we verify an email address with the use of SMTP protocol, how to identify a good email address, and the best ways on how to clean up a mailing list are all answered in this article!

Knowing the Basics

To comprehend email verification api better, it is important that we start with understanding what a valid email address is. By definition, an email is valid if there is a mail server that will accept a message to that address. Accepting a message entails that the server read the contents of the message from the sender. However, this does not necessarily mean that the message will be delivered to the mailbox of the recipient. But take note that this does not indicate that the message will be read by its recipient.

SMTP protocol is used in the process of verifying an email address. There are certain commands that are being used in the process: EXPN, VRFY, RCPT TO. EXPN and VRFY are not commonly enabled in the mail systems of today, while RCPT TO is the most common verification command.

Here are the steps in using the RCPT TO command:

Step 1: Identify the IP address of the target mail server.
Step 2: Launch a connection to the target mail server.
Step 3: Send EHLO or HELO command.
Step 4: Send MAIL FROM command.
Step 5: Send RCPT TO command.

Mail Servers Target

The existence of the MX records for the domain of the email address that needs to be verified should be initially checked. MX records are the DNS records that capture information about mail servers handling emails for the specific domain. There are no valid email addresses that exist if MX records do not exist as well.

Why is this very important? Take this example wherein the sole MX server is being selected from the list. When trying to establish a connection to it so an email can be verified, the server would not respond for whatever reason. Otherwise, its response will report an impermanent error due to a previous issue with this particular service. Failure to try other available mail servers would result to having a wrong result. It is feasible though that another server will be perfectly fine and would yield the correct answers. Trying another server can be a resolution when one server becomes a problem. Problems would include not being able to connect to SMTP port, non-OK responses to EHLO/HELO or MAIL FROM commands, or no greeting received.
