Looking for an email list scrubber? You’re in the right place!

Email marketers often agree that your list is your goldmine.

Now, here’s the part you don’t often hear: up to 25% of that goldmine could be fool’s gold!

“Bad emails? No big deal,” you might think.

But turn a blind eye to list hygiene; and these bad addresses send bounce rates soaring!

When that happens, your bottom line takes a hit (since you can’t land in the inbox).

That’s why I’m bringing you a review of six email list scrubbers that are worth your time and investment:

  • Emailable
  • Clearout
  • Hunter
  • ZeroBounce
  • Bounceless
  • Bouncer

Let’s dive in!

No time to waste?

Check out our favourite tool Emailable!

Emailable (Best Email Scrubber)

Email deliverability can make or break a campaign. As marketers, we’ve all felt the sting of meticulously crafted emails landing in the spam folder or worse, bouncing back entirely.

Emailable is an email list cleaner that eliminates irrelevant, spammy, and invalid emails from your database.

It offers:

  • Bulk email checking
  • Email list cleaning automation
  • Real-time email verification
  • A comprehensive deliverability tool suite

But here’s where Emailable really shines: its speed. In a world where every minute counts, Emailable gets it.

It’s fast, efficient, and doesn’t keep you waiting.

Many users report switching over because their old tools took hours or days to complete email verification. In my experience, scrubbing my data only takes a few seconds. For a large list, it will be slightly longer.

The simplicity of Emailable’s email cleaning process is noteworthy. It provides clear descriptions of each type of result, making it easy to act on.

Emailable is no slouch when it comes to security, either. Emailable safeguards data with GDPR compliance and 256-bit TLS encryption.

Also, the platform integrates with the email service provider, customer relationship manager, and marketing platforms you already use.

The pricing is competitive, and most importantly, it works even better than advertised.

You can be confident that your email marketing efforts are built on a solid foundation of reliable, verified email addresses.

Clearout (#2 Email Scrubber)

Clearout offers a suite of tools designed to streamline and enhance email marketing efforts.

From verifying emails at the point of capture to maintaining data hygiene, Clearout excels.

What sets Clearout apart as an email scrubber is its accuracy. It not only removes invalid emails but also ensures that the emails that do make it through are high quality.

We can avoid spam traps, which keeps my open rates high (and overall ROI positive).

Clearout’s speed is another standout feature. Whether I’m verifying a handful of emails or a list of thousands, Clearout easily handles it.

This efficiency is crucial – no more waiting days for results.

Data security is a top priority, and Clearout doesn’t disappoint. Data is well-protected with 256-bit SSL encryption and adherence to GDPR, SOC 2 Type 2, and ISO norms.

The flexibility of Clearout’s integration capabilities is also a big plus. The rest API is adaptable and can integrate with any programming language.

Looking at other user reviews, it’s clear that my positive experience with Clearout is not unique. Users have praised its accuracy, affordability, and user-friendly interface.

This kind of feedback reinforces my confidence in the platform.

  • Ensures email list accuracy.
  • Helps maintain sender reputation
  • Prevents accidental data loss
  • Great for large email lists

1 million credits $1,100 ($0.0011) $880 ($0.00088), at its core, is a tool designed to streamline the process of cold outreach by finding and verifying professional email addresses. (By the way, here’s our full review)

Compared to tools like Emailable and ZeroBounce, which focus more on bulk email verification, focuses more on outbound lead generation.

Yes – bulk email verification is a part of that, so there is also some overlap.’s features include:

  • Domain Search
  • Email Finder
  • Email Verifier
  • Email Campaigns

The process begins with the Domain Search feature. Instead of spending hours trawling through LinkedIn or company websites, I enter the domain name into

In an instant, I have a list of professional email addresses from that domain.

Once I have these potential leads, the next step is to ensure the emails are valid. At this point, I’ll use the verifier, which ensures 95% accuracy.

However, where truly stands out is its Email Campaigns feature.

Unlike other tools that stop at email verification, takes it a step further by allowing me to compose, schedule, and track email campaigns directly from the platform.

In terms of use cases, excels in roles where outbound lead generation is key.

For example:

  • Salespeople targeting decision-makers
  • Bloggers performing backlink outreach

  • Confirms the validity of emails.
  • Improves email deliverability.
  • Lead qualification
  • Transparency on data origin
  • Follow up automation


  • Some verified emails may be non-existent

ZeroBounce is a comprehensive email validation service that offers:

  • Email list validation
  • Email list cleaning service
  • Additional data appending
  • Improved deliverability

The accuracy is impressive, with a 99% accuracy claim that holds up in practice.

This was evident in the case of MediaShares, where their bounce rate dropped from 12% almost to 0% after using ZeroBounce.

It’s GDPR, SOC 2 Type 2, and PCI compliant and uses military-grade data encryption to protect data.

ZeroBounce integrates with existing email marketing platforms and CRMs, enabling smooth data transfer. The real-time verification feature is also a bonus, validating emails as they are collected.

The Activity Data service is a unique feature that provides insights into subscriber engagement, allowing for improved email list performance.

The AI-driven email scoring system is another plus, predicting subscriber interaction with your emails.

ZeroBounce’s reputation is strong, with numerous positive customer reviews and testimonials. They also have a free trial for Niche Pursuits readers, allowing you to test the tool’s capabilities before purchasing.

Pros vs Cons
