How to Validate an Email Address

If you’re like most people, you get hundreds of spam emails every week. It’s impossible to manually check every email you receive, so use Clean Email to organize them into easy-to-review bundles that you can manage just like a single email.

1. Email Checker

Fake email messages are a huge problem nowadays, so many email checkers, also known as email verifiers, exist to validate email addresses with a few clicks. There are so many free email checkers available that you will never have to pay to use one. While each tool is unique, they are all simple to use and require no registration.

2. Send an Email to the Address

The simplest way to test an email address is to send it an email.

If you send email to a fake email address, it will bounce back and you will receive the following message from your email provider:

Your message was not delivered to [email protected] because the address was invalid. Recheck for typos or extra spaces and retry.


Message not delivered: Your message to [email protected] was not delivered. Then try again in a few minutes.

Remember that some email providers use a catch-all email address to catch messages sent to incorrect email addresses.

3. Lookup IP Address

Don’t worry: an IP address lookup is much simpler than it appears. An IP address lookup is used to locate an IP address. Each email message contains the server’s IP address. Normally, this IP address is hidden, but if you choose to view the message source, it will be right there, under “received from.”

Simply copy the IP address and paste it into an online IP address lookup tool like What Is My IP Address. In a few seconds, you’ll see the IP address’s ISP, organization, and location. If the IP address is from a country you don’t recognize, be suspicious.

4. Google the address

This method cannot tell if an email address is valid or not. It works because most people nowadays have an online presence—some own websites, others are on social media. Google and Bing continuously crawl the internet, indexing everything they find. That’s why real email addresses can be found with a simple search, but fake email addresses can’t.

5. Password Recovery

Have you ever tried to recover an old email address only to be told that it couldn’t be found? Google, Yahoo, and Microsoft all use a simple email address checker to inform users who forget their password that they also forgot their email address.

You can use this email address checker to verify emails from,, and Go to the recovery page and enter the email address you want to verify:
