“Hi, I’m just examining if this email address is valid. If you’re viewing this email, please let me know.”

If you send an email like this to a false email address, your message will bounce back, and you’ll get a message similar to the following one from your email provider:

Method 3: Perform an IP Address Lookup

No need to worry: doing an IP address lookup is much easier and less technical than it sounds. The idea of an IP address lookup is to find the geolocation of an IP address. Each email message you receive comes with the IP address of the server it started from. Normally, you can’t see this IP address because it’s hidden but want to view the source of the message, it will be right there, under “received from.”

All you require 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.

If the IP address is located in a country you wouldn’t expect, be very unusual because someone could be spoofing it.


Method 4: Email Checker (Email Validation Services)

Fake email messages are an immense problem today, which is why it shouldn’t amaze you to learn that there are many email checkers, also known as email verifiers, that can be used to verify email addresses with a couple of clicks. Free email checkers normally limit the number of email addresses you can validate in a month, but there are so many of them to pick from that you won’t ever have to spend any huge money just to use a valid email checker.

While each email checker is somewhat different, they are all very easy to use and sometimes don’t even require you to register.

Method 5: Search the Address in Google

This approach 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 their own websites, while others are active on social media. Major search engines like Google or Bing regularly crawl the internet, listing everything they find.
