11 Email Verification Tools to Check Out in 2023

What can go wrong when you are just sending email newsletters to your subscribers, right? Well, here’s a fact for you: 48% of global mail is being marked as junk. Yikes!

This means that your emails aren’t really getting through to people because they are either getting caught in spam filters, getting blocked by the user’s ISP, or being sent to invalid email addresses.

Your email list could be hanging by a thread and you wouldn’t even know it. This is why email verification is indispensable in email marketing!

What’s that, you ask? We’ll tell you all about it in this blog.

And while we’re at it, we will also give you a list of awesome email verification tools that you can use to check up on all your email activities!

So, what are you waiting for? Dive right in!

Email Verification, What’s That?

Email verification is the process of verifying an email address to find out whether it’s valid and active. This basically means checking whether a REAL person with a REAL email address is the one interacting with you.

Apart from identifying invalid and fake emails, this process also includes pinpointing misspelled emails and correcting them, determining the bounce rates, and reporting when an email was last opened.

It ensures that your emails don’t get flagged as spam or get blocked and blacklisted by IP addresses.

Why You Must Verify Emails!

Don’t think that just because you follow organic practices and adhere to all standards of email marketing, you will be safe from falling into spam traps and other risks that can adversely affect your sender reputation.

It can result in your emails not even making it to inboxes, and you know what that means? You lose your customers, your money, and your time.

According to Marketing Sherpa, email addresses degrade at a rate of 22% per annum. That means if you have a mailing list of 100,000 addresses, more than 20,000 of them will be invalid in a single year!

That’s not a percentage that you would want to maintain each year. That’s why there is a need for continuous updates and checks of your mailing list.

Take a look at the some of the benefits of verifying emails to have a better understanding:

  • Email verification ensures that your email lists are always fresh and up-to-date by regularly removing unengaged users and fake email addresses.
  • It does everything to eliminate your high bounce rates
  • By email verification, you can identify and flag email accounts that usually mark emails as spam.
  • It helps you maintain a high sender reputation by preventing you from getting blacklisted or blocked.
  • It improves your overall email deliverability rates.

Now that you know the importance of verifying emails, let’s go over the list of some really cool email verification tools. Just jump right in!
