What is Email Validation?

Email verification confirms the state of email addresses by proving the existence of an inbox and the reception of active emails, allowing businesses to measure email marketing campaign effectiveness accurately.

Now there are 2 types of Email Verification:

  • Ondemand: such as regularly clearing an address list.
  • Real-time: This is done as soon as data is entered into a system using an API.
    To ensure that fresh data is always correct and that older data is regularly cleansed, many firms combine the two types of data.

What is the length of time needed for email address verification?

The time it takes to verify an email address will entirely depend on your infrastructure software and server authentication. The number of emails sent, server load, unique domains in your list, and server policies all influence this process.

However, we use APIs in sign-up forms to ensure that email address verification only takes a few milliseconds and doesn’t disrupt user activities. APIs do not slow down the process; instead, they enhance the user experience.

Method 1: Send an Email to the Address

If you have no clue how to check if an email address is valid the simplest way to determine whether an email is valid is to respond to it. When starting, this method is ideal for marketers with a small marketing list.

Simply adding a few new addresses to your list each month, is also a wise decision.

Also, you may write something like this if you decide to verify each genuine email address one by one:

Hello, Just making sure this address is correct. Tell me whether you are receiving this email, please.

When you send a message like this to an invalid address, it bounces back and your email provider sends you something like this:

Not Delivered Message: An issue occurred when sending your message to [email protected]. Please resend the email in a few minutes, or view the technical details below.


Address Not Found: The address could not be located, so your message to [email protected] was not delivered. After making sure there are no typos or extra spaces, try again.

Remember that certain email providers use a safety net called catch-all email address to intercept messages that are sent to the wrong address. A message sent to a catch-all address is delivered.

This serves as a catch-all receiver for emails sent to addresses that don’t exist within that domain (such as [email address removed]). It keeps messages from instantly bouncing, but it doesn’t ensure that your intended recipient will receive them.

Method 2: Using a Free Email Verifier

Because of the prevalence of fake emails in today’s world, you shouldn’t be surprised to hear that there are numerous email checkers, often referred to as email verifiers, that can be used to quickly authenticate email addresses.

To verify bulk email lists, Use an email verifier.

Free Email Verifiers

Method 3: Syntax Checking

Email validation relies heavily on email syntax and formatting checks to find and fix email address errors before they affect subscriber list quality or cause deliverability problems. 

So it’s a very straightforward way how to check if an email is valid by checking the email address syntax.

That verifies the email address is formatted correctly, such as [email protected].”

Syntax checkers verify some components, to confirm that email addresses contain the “@” symbol, a domain name with at least one period (such as “.com,” “.org”), and valid characters without spaces or special characters, use regular expressions or validation libraries.

Method 4: Domain Verification

This step verifies that the email address’s domain is active and able to receive emails.

To determine which DNS records are authoritative for the domain, run a Domain Name System (DNS) query.

A successful lookup verifies the domain’s presence and configuration using online tools such as MXToolbox and DNSstuff and verifies the MX records for a domain.

The MX records should not be empty. Why? It is more likely that the email address is operational if there are valid MX records. Nearly all email verification providers follow this standard practice.

Here’s an example of a DNS lookup on MXToolbox:

You Should Also Check Your Domain Age

Navigate to New Message →

  • Go to compose,
  • In the recipient section, enter the email address,
  • Once the email is entered, hover the mouse pointer over the email address.

In the hover card, the user’s complete name and picture will show up of the lead if the email address is valid and connected to a Google account. That the email is legitimate, active, and connected to a particular person can all be verified with this easy check.

  • You can create a new or already existing Google Sheets spreadsheet.
  • Enter the email address.
  • Hover your mouse pointer over the cell that contains the email address.

Method 6: Check the Email Address in Google Search

This method can verify whether an email address is valid, but it cannot determine if it is fake. It works because most people are online and post their email addresses on their websites, social media profiles, and public discussion groups like Reddit and Quora.

Major search engines like Google and Bing index everything they find on the internet as they continuously scan through it.

As a result, most legitimate addresses can be found with a simple search engine query, but fake addresses cannot. See the example below!

Method 7: Try Password Recovery

Have you ever tried to retrieve a previous email address, only to be told by your service provider that the address was not found?

During the account recovery process, the three largest email providers – Google, Yahoo, and Microsoft use a basic email address checker. This checker can verify whether the email address was correctly entered into your forms and can help users recover their passwords.


Anytime you receive a message from a @gmail.com, @yahoo.com, or @outlook.com domain, you can take advantage of this email address checker.

Just navigate to the relevant recovery page and input the address you wish to confirm:

It can be ineffective to use this strategy for email validity because it can take a while and produce insufficient results, especially for marketers with large lists and different addresses.
