Spammers have become so skilled in their craft that one must learn how to check if an email is valid to reliably distinguish legitimate emails from fake ones. In this article, we provide 5 different methods for checking if an email is valid, and most of them are so simple that anyone can follow them with ease.
If you’re like most people, you probably receive hundreds of emails every week, many of them spam. It would be impossible to manually check the validity of every single email you receive, which is why you should always start by using Clean Email to organize all of your emails into easy-to-review bundles that you can manage just as easily as if you were managing a single email.
Just like the 5 methods on how to check if an email is valid that we talk about in detail below, Clean Email can be used with all popular email services, including Gmail, Outlook, Yahoo, iCloud, Yandex, Fastmail, AOL, and others.
Perhaps the most straightforward way how to check if an email address is valid is to simply send an email to it. Just write something like:
“Hi, I’m just checking if this email address is valid. If you’re reading this email, please let me know.”
If you send an email like this to an email address that’s fake, your message will bounce back, and you’ll receive a message similar to the following one from your email provider:
Message not Delivered: There was a problem delivering your message to email@example.com. See the technical details below, or try resending in a few minutes.
Address not Found: Your message wasn't delivered to firstname.lastname@example.org because the address couldn't be found. Check for typos or unnecessary spaces and try again.
Just keep in mind that some email providers use something that’s called a catch-all email address to catch email messages sent to incorrect email address.
Have you ever tried to recover a very old email address only to be informed by your email service that the address couldn’t be found? The three major email providers—Google, Yahoo, and Microsoft—all use a simple email address checker during the account recovery process to inform users who don’t know their password that they also don’t remember their email address correctly.
You can use this email address checker to your advantage whenever you receive an email from @gmail.com, @yahoo.com, or @outlook.com domain. Simply go to the corresponding recovery page and enter the email address that you’re are trying to verify:
Don’t worry: performing an IP address lookup is much easier and less technical than it sounds. The purpose of an IP address lookup is to determine the geolocation of an IP address. Each email message you receive comes with the IP address of the server it originated from. Normally, you can’t see this IP address because it’s hidden, but choose to view the source of the message, it will be right there, under “received from.”
All you need to do is copy the IP address and paste it in any readily available online IP address lookup tool, such as the one provided by What Is My IP Address. After only a few seconds, you will see the ISP and organization associated with the IP address as well as its location. If the IP address is located in a country you wouldn’t expect, be very suspicious because someone could be spoofing it.
Fake email messages are a huge problem today, which is why it shouldn’t surprise you to learn that there are many email checkers, also known as email verifiers, that can be used to validate email addresses with a couple of clicks. Free email checkers typically limit the number of email addresses you can validate in a month, but there are so many of them to choose from that you won’t ever have to spend any money just to use an email checker.
Here are our favorite free email verifiers:

This method won’t tell that an email address is fake, but it can tell you that an email address is valid. It works because most people these days have a presence on the internet—some have their own websites, while others are active on social media. Major search engines like Google or Bing constantly crawl the internet, indexing everything they find. That’s why most email addresses that belong to real people can be found with a simple search engine query, while fake email addresses can’t.
Of course, some people do what they can to keep their email addresses private, but that’s where the previous 4 methods on how to check if an email is valid come in.
