How Can You Check If An Email Address Is Valid?

While sending one email is quick and easy, sending a lot– such as email marketing or lead outreach – starts to take a considerable amount of time, energy, and resources. The last thing you want to do is waste that work on emails that don’t exist, which is why it is important to know the basics of checking if emails are valid.

Don’t worry, it’s not as hard as it sounds, and we’re going to walk you through six simple methods to help you weed out the fakes and focus all your productive power on the emails that matter.

How To Make Sure An Email Is Valid

Sending emails to fake or invalid accounts doesn’t only waste your time and energy, it can also have a significant negative impact on your domain reputation and lead to an inflated bounce rate. This can in turn lead to email services marking your messages as spam, meaning that even those sent to valid addresses could end up unseen.

On the other hand, if you learn how to check if emails are valid, which is very simple these days, you can increase your deliverability rate, avoid spam filters, and have a more productive email outreach operation.

1. Send Them an Email!

Possibly the simplest way to tell if an email is valid is to just send an email to the address. This doesn’t work if you’ve got a list as long as your arm to get through, but if it’s only a few addresses – or you’re building a list bit by bit – it doesn’t take too long and will pay off in the long run.

Make the message short but polite enough that if the address is valid, you don’t scare the recipient away! If the email address is not valid, then the message will bounce back with a report saying “Message not delivered”, “Address not found” or similar.

There is the possibility that if the address isn’t valid but the company email domain is, then your message will be funneled into a catch-all address. In this case, you’ll get no error message or response. Additionally, not everyone will reply even if they are a real person and have read your message.

Due to these possibilities, it’s always worth doubling down with our next method…

2. Use Read Receipts to Check if an Email is Delivered and Read

Sitting around and waiting for a response is all well and good, but if you want to speed things up a little and have more confidence in knowing whether your emails are getting through, it’s worth sending them via an email client that offers read receipts.

Email trackers are simple tools that let you know whether an email has been opened and by extension, to check if emails are valid. There are plenty of options out there that vary by cost and simplicity, but the easiest route for most people is going to be using an email client that offers read receipts as standard, like Spike.

3. Google the Email Address

The next super-simple way to check if an email address is valid is to use a search engine. This won’t tell you explicitly whether or not the email is real, but since most people use the same email address across the web, if you search for a real address online it will show you their digital footprint. If you search for a fake address, then this digital footprint won’t show up (no social channels, etc).

Try it now with your own email address and you’ll see what we mean!

4. How to Make Sure an Email Is Valid Using Password Recovery

Most applications offer some form of password recovery, and if you’ve ever accidentally typed in your account details wrong while trying to use it, you’ll have been greeted with a relatively similar message – “We’re sorry, this account does not exist.”

Well, all three major email providers – Google Microsoft, and Yahoo – offer this password recovery and so can be used to figure out if an account from one of their domains is valid.

If you’re worried that an address with a @gmail.com, @yahoo.com, or @outlook.com domain is spoofed or fraudulent, you can enter it into the respective company’s recovery page and look for the “this account does not exist” message.

Of course, this only tells you if the account is real, not whether it is active, in use, being used for nefarious purposes, etc., so don’t put all your faith in it. Furthermore, going through this process one account at a time is extremely laborious.

5. Look Up the IP Address of The Email

When you receive an email, it comes with the IP address of the server it originated from. You can use this IP address to determine the geolocation of the sender server. It sounds pretty high-tech but is actually really simple.

You will now be shown the location of the server where that email originated. Most of the time, this will not be the same as the location of the person who sent it, since most people don’t have onsite email servers. However, it is useful to check whether the location shown is in a place you wouldn’t expect.

6. How Can You Check If An Email Address Is Valid With An Email Checker

The fastest, simplest, and more accurate way to validate email addresses at scale is through the use of a dedicated email checker. These are services that allow you to bulk check email addresses before sending out emails. Any good email checker will identify:

Beyond these essential elements, you should also judge potential email checkers according to price, usability, customer service, and any factors that are unique to your use case.
