How Can I Test If An Email Is Valid – 5 Email Checker Tips

Email marketing is a major part of any digital marketing strategy. In order for your email campaigns to be successful, you need to make sure that the email addresses on your list are valid and that your bounce rate is minimal.

There are a number of ways to validate an email address, including, but not limited to using an email checker. Here are 5 tips to help you validate an email address and prevent your emails from being flagged as spam.

1. Use A Reliable Email Checker Service

There are many email checker services available online, but not all of them are created equal. Some services may only verify that an email address exists, while others will also confirm that the email address is active and can receive mail.

Either way, it’s up to you to make sure to choose a reputable service that offers a high degree of accuracy.

How do you do that?

By doing your due diligence and researching several tools until you find the one that suits your needs the best.

2. Check For Typos And Common Mistakes

While time-consuming and very tedious (and downright impossible to perform if you have an extensive email list), checking for typos is a good way to figure out if the email’s valid or not. So, make sure to always double-check the email address before adding it to your list.

Look for common mistakes like “” or “”, as there is no way you’ll be able to actually identify a typo in a username.

Now, if this is an automated process for you, this will be harder to do, unless you’re using verification or an email checker tool that will automatically identify common typos or flagged addresses and exclude them from your list.

3. Comb An Email Database

Another thing you can do is comb an email database to try and find similar addresses. These databases store thousands or even millions of email addresses, along with additional info like addresses and phone numbers, which will, in a way, confirm that an address is legit.

The only problem is – these databases can be outdated, which means the info there might not be accurate, which could actually result in a worse bounce rate, rather than better.

4. Send A Test Email

One of the best ways to confirm that an email address is valid is to simply send a test email to it. If you don’t receive a bounce-back message, then you can assume that the email address is valid.

Just be sure to use a subject line and message body that is unlikely to trigger any spam filters and make sure you don’t the primary email. Have a test address set up, so even if you do encounter a lot of invalid addresses, your main account isn’t affected or “blacklisted”.

5. Check The Bounced Emails Report

If you’re already sending emails to a list, then you can check your bounced emails report to see if there are any invalid email addresses on it. Any email addresses that consistently bounce back should be removed from your list.

Pair this with the previous method, and you’ll have a squeaky clean email list from now on.


By following these tips, you can be sure that the email addresses on your list are valid and that your messages are getting delivered to the right people. So, make sure to put them into practice!
