Verify an email address without sending an email

There are several ways to do an email verification without the need to actually send an email to that address. Sending emails to inexistent addresses will cause a bounce and in time this might generate problems for you. Since servers can, and often enough do, blacklist addresses that generate a large number of hard bounces.

From a variety of options for email verification software to a step by step guide on how to do it yourself. Here we can give you many alternatives for approaching a situation where you need to verify an email address without endangering your reputation score with a server.

Do it yourself.

Almost anyone can hire a verification service, especially when it comes to large lists of addresses. But if you have a relatively low number and want to check them out by yourself, this could be a good option.

A side from money saving, this alternative let’s you remain in control of what you do and how you do it. Getting first hand results that you know you can rely on.

Ping an address to validate it.

Every time you send an email, the message goes to a SMTP server which in turn looks for the “Mail Exchange” (MX) records of the recipient’s domain. If you send a mail to [email protected], the server will search for the MX records of the gmail.com domain. If they should exist then it determines if the user name exist within or not.

Based on this process we can establish a way to check if an address really does exist. And you can do this all by yourself. All you’re going to need is your computer and an internet connection.

Step 1.

Enable telnet or use PuTTy, if you’re using windows that is. For Mac users just open iTerm app.

Step 2.

In the command prompt type, the following: “nslookup -type=mx gamil.com”. This command will query the server for that particular domain. We have actually specified the type as MX. This will extract and list the MX records for that email domain. In case you need to do this for another domain, you can replace the “gmail.com” with the other domain.

You should see something like this.

Step 3.

As you can see. In this case, as in many, there are multiple MX records for a domain. Just pick one to proceed. Anyone will do for this example. Now we’re going to pretend to send an email to that server.

Go to the command prompt and type the following in the same order.

telnet gmail-smtp-in.l.google.com 25” (Connect to the server).

Helo” (just a friendly salute).

mail from:[email protected]” (Identify yourself).

rcpt to:[email protected]” (The recipients address).

The servers answer to the “rcpt” command will give us the information we need. If the address exists in the records you choose then you’ll get an “OK”. If that’s not the case then you will likely receive a 550 error.

Commonly this error says something like “The email account that you tried to reach does not exist.” Or “The email account that you tried to reach is disabled”.

If that’s the case then you can be sure that the email address doesn’t exist, at least not in the records or in the server.

Get help.
