What is Email Validation: Everything You Need to Know

The ROI of email marketing can be 122% or more without a doubt. But it’s possible only if you do it correctly. The foundation of any email marketing strategy is the email list, which should be clean and deliverable. The first thing you must do is email validation. But what is email validation? What are its benefits? And how to do it correctly?

I’ll help you answer all these questions in this post. You’ll get started with a bang in email marketing, even if you’re a beginner. So let’s get started right away.

What is email validation?

The solution? Email validation, of course. It’s a process of verifying an email address to confirm its validity and existence. It also ensures if the email address is deliverable and has a reliable domain such as Gmail. But why must you do the email validation?

So you made a great effort in collecting email addresses using different ways. And you sent an important email to the vast contact list. But you just came to know that most of the contacts were not even valid. Maybe some of them aren’t correctly formatted. 

Why You Must do email validation

Let’s suppose you have collected email addresses and run an email campaign without email validation. You’ll get hard bounces for invalid email addresses. And the existing email recipients will get their emails, right? Wrong! 

Hard bounces impair your sender’s reputation, and a poor reputation means decreased email deliverability. So even if some email addresses exist, you’ll not be able to deliver the email to their inboxes. And that may be a big problem for an entire email marketing team. 


How to Verify Email Addresses Without Sending Emails

An email address consists of an @ symbol, a dot, and ASCII characters. The first part has private information, and the second one has the domain name in which the email is registered. Let me get more detailed here.

The first part of the email address contains:

  • Uppercase and lowercase alphabets like A, b, c, and more. 
  • Special symbols like @, _, – or more. 
  • Full stop, dot, etc. 

And the second part of the email address contains:

  • Dots
  • Hyphens
  • Digits
  • Letters
