What is Email Validation

In-depth information on email address validation will be covered in this article, along with answers to frequently asked questions and suggestions for creating an effective email list for upcoming marketing campaigns.


What is Email Validation?

Before reading further, you should have a basic understanding of what email validation entails, which I will discuss below.

Email validation is a required practice every email marketer must incorporate into their email marketing strategies. Because email validation ensures that the email addresses in your email lists are valid, verifiable, deliverable, and, most importantly, exist, the reasons for these factors will be discussed further below.

Why you must validate email addresses

The success of your email marketing strategies as an email marketer is dependent on the successful delivery of your emails to your contact lists. Assume you have a large email contact list that has not been validated and you went to send your marketing campaigns to these email addresses and at the end of the day, your emails received a hard bounce. This will reduce your sender’s reputation, which will reduce your chances of email deliverability and your emails will end up in the junk or spam box of existing email contacts.


To avoid having a bad reputation and poor deliverability, consider the following reasons why you should validate email addresses.

  • It boosts engagement while lowering the cost of email marketing.
  • It reduces high bounce rates and increases deliverability.
  • It improves your brand’s reputation.

How Does Email Validation Work

The process of validating email addresses is known as email validation. It entails double-checking the syntax, formatting, and spelling of your email contacts. It also includes actions like pinging the email box or looking up the DNS.

The steps listed below can help you validate email addresses.

  • Verify your spellings.
  • Perform syntax checking.
  • Look for the abandoned email addresses.
  • Check the DNS for the contact.
  • Ping the email box

Email validation can be carried out using software or a piece of code. There are numerous tools available for this, some of which are automated and others that can be completed manually but may take a while.

How to validate email addresses

Depending on your preferences, email validation can be done manually or automatically. While manual email validation uses codes like JavaScript, jQuery, React JS, and many others that can be embedded on your desired web pages, automatic email validation uses paid email validation services and tools.

How To Add Email Validation In Html

If you want to manually verify email addresses, you must include a JavaScript, jQuery, or React JS email address validation code on your website page.


It should be noted that this method takes much longer than email validation services.

Email Validation In JavaScript

This JavaScript code validates email addresses manually all you have to do is copy this code and place it on a new page with filename.js.

// Email Validation Code Snippet
Function EmailValidation(enteredEmail)

{var mail_format=/^w+([.-]?W+)*@W+([.-]w+)*(.w{2,3})+$/;



alert(“Good! This is a valid email!);


return true;




alert(“Email Address Not Valid Email”


return false;



If you want to use JavaScript in HTML, copy and paste the code below. And save the file with the extension .html.


<div class="”mail”">
<h2>Enter the email address for validation</h2>
<form action="”#”" name="&quot;form”">
 	<li><input name="’text1’" type="’text’/" /></li>
 	<li class="”Validate”"><input name="Validate" type="Submit” value=" /></li>
<script src=”filename.js”></script>
