Email Validity Tools to Add Higher Quality Leads to Your List

Do you want to collect genuine emails and remove invalid ones from your contact list? Then you’re probably in the market for the best email validity tools you can find.

Because with a generic email list, it’s common to have incorrect, outdated, and sometimes even spam email addresses. This results in an inflated email list with low deliverability and click-through rates.

But once you clean up your list, you can be sure your emails are going only to valid email addresses.

That’s why we’ve picked 8 email validity tools that you can use to check leads and increase response rates.

Before diving into our list of tools, let’s get crystal clear on why you’d want to validate email addresses in the first place.

Why Verify Email Addresses

Email marketing can be tricky. If you’re sending a lot of emails with most of them bouncing or being undelivered, your email address can be flagged as spam.

When that happens, your emails won’t be delivered to the portion of your list that’s engaged and excited to receive your content.

Plus, when you use an email service provider (ESP), they usually charge you based on the number of contacts on your list. That means you might be paying for contacts that will never convert into paying customers.

But email verification tools scan your contact list and remove email addresses that are:

  • Not formatted properly
  • Disposable/temporary
  • Created by bots
  • Have been blacklisted
  • Have invalid domain names
  • Role-based like admin@, support@, help@
  • Don’t have a valid MX record

In other words, email validity tools make it easy to prevent spam signups and remove invalid emails from your list.

The end result is that you’ll pay less and earn more from your email marketing campaigns.

Now that we know WHY you’d want to verify your email addresses, let’s dive into how you can with these 8 email validity tools.

Top Email Validity Tools

We’ve listed the best email validity tools in the market based on accuracy, features, and cost.

1. OptinMonster

OptinMonster is the #1 lead generation software in the world to grow your email list exponentially. It lets you create highly targeted optin campaigns (like popups, floating bars, sidebar widgets, and more).

OptinMonster’s targeting features help bring in the right crowd that is more likely to engage with your emails and convert them into paying customers.

Plus, it comes with built-in tools to prevent spam from getting on your list like honeypot protection, reCaptcha, and lead verification.

1. Honeypot Bot Protection

Spambots automatically fill out all fields in a form. The honeypot technique is used to trick bots by creating a hidden form field that regular visitors can’t see.

When the hidden field is filled, OptinMonster will prevent the form from being submitted. This protection is already set up and enabled inside the OptinMonster software so you won’t need to do anything.

2. Google ReCAPTCHA Protection

reCaptcha is a free service provided by Google that uses a “CAPTCHA” test to tell the difference between spambots and humans. You can sign up for Google reCaptcha and then add it to your OptinMonster account.

Enter site key and secret key-min

After that, you’ll be able to enable reCaptcha on your optin forms at the click of a button.

Enable reCaptcha turned on

Then you’ll see that your lead generation campaign is protected by reCaptcha when it’s published on your site.

With that, spambots won’t be able to fill out your signup forms.

3. TruLead® Lead Verification

TruLead® is OptinMonster’s own email validity tool that verifies your lead before they’re added to your contact list.

It autocorrects typical misspellings from popular email service providers like Gmail, Yahoo, Hotmail, and others. Plus, it lets you can block temporary, free, role-based emails, and even lets you block IP addresses.

You can access this lead verification feature inside the OptinMonster dashboard.

This lets you create filters to block IP addresses, patterns, strings, characters, and much more. You can also autocorrect emails, and block temporary and free ones.

More filter options to verify email addresses

So when a visitor tries to enter a free email address instead of their professional one, they’ll see an error message like this:

This error tells them why the form won’t be submitted and how they can fix it.

And OptinMonster’s lead verification doesn’t stop there. TruLead® stores your rejected leads for 30 days. That means you can manually review rejected submissions and delete them or add them to your list.
