What is email verification and how to validate email addresses?

In terms of email marketing this is a process of checking email address to see if it is dead or we can keep it in mass email list. When I say dead I mean that messages we send to a dead address bounces back with messages like this:

Delivery to the following recipient failed permanently:

     whoever@example.net

 Technical details of permanent failure:

 Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unknown user (state 14).

In this particular case this dead email wasn't ever born (550 550 Unknown user (state 14). This called hard bounce. Alright, lets make it simple. There are two types of bounces.

• Hard bounce. It happens when during email check server says “User unknown” or gives you a similar message. This is a permanent problem. Email is invalid. Email is dead or never existed.
• Soft bounce. Server says “mailbox is full” or all kind of a temporary problems. You got a chance to email it later when it is back to normal. Decide whether to keep it or move into a list to check again later.

Now, how to validate or check email addresses to see if they will bounce back?

You need email verifier software or online verification service. Software is good when you want to go unlimited and not to bother about monthly payment. Online verifiers normally have monthly subscriptions with recurring payment. Sometimes online is faster and more accurate. It always needs testing. Never get verifier from companies who do not offer free trials. Always call support prior to purchase to ask how their service checks validity of email addresses. Ensure they know how. Presales support must be of the same quality as tech support you get after you purchase. 

Remember, when you send mass mail the bounces you get the higher chances of getting blacklisted by SMTP server provider or mail service like mailchimp, iContact etc.
