Hunter.io and ZeroBounce accuracy comparison

Accurate email validation results are essential for your email marketing.

All of the potential benefits - lower email bounce rates, better inbox visibility, stronger conversion rates, etc. - are unattainable if your email list contains invalid email addresses.

ZeroBounce accuracy

guaranteed

Hunter.io accuracy

95%

(minimum)

ZeroBounce outpaces Hunter.io in terms of accuracy. Furthermore, you’re protected from risk as your results have a money-back guarantee. Your email bounce rate will be below 2% after using the platform.

Additionally - ZeroBounce has a track record of consistently yielding fewer than 1% “unknown” results. It’s able to accurately verify more email domains, including complex ones, while also circumventing common spam blockers.

What types of email addresses does Hunter.io identify?

Speaking of “unknown” results, the types of email addresses a service can identify are just as important as accuracy.

Types of emails Hunter.io identifies

Valid
emails

Disposable
emails

Invalid
emails

Due to its limitations, Hunter.io cannot classify additional address types that may be on your list.

When you validate your email lists with ZeroBounce, you gain deeper insights into those email addresses. For example, abuse emails are ‘valid.’ But they belong to known spam complainers who are likely to increase your spam complaint rate. Though your emails won’t bounce, it’s better to delete those abusers to protect your company’s email reputation.

Similarly, you don’t want an email verifier to misclassify a potential lead as “invalid” or “undeliverable.” Instead, you can use Email Scoring and Activity Data to learn more about the address owner’s behaviors and make your own judgments about whether or not it’s worth pursuing that email lead.

ZeroBounce offers more email data beyond validation status

Identifying email validity is essential for preventing email bounces. But that’s just the first step to improving your email results.

Once you reach the inbox, you need help getting subscribers to open, click, and engage with the content in your email.

At no additional cost, ZeroBounce provides a variety of appended data when available. This information includes name, gender, geolocation, email domain information, and IP information. By better understanding the history of the email address, you can make better decisions regarding segmentation and targeting.

ZeroBounce also provides these additional email insights:

  • Email Scoring - For 1 credit, you can Score a validated email address to determine the quality of the lead.
  • Activity Data - For 1 credit, you can retrieve an email address’s Activity Data to find out if they’ve opened, clicked, forwarded, or unsubscribed from emails in the last 30-180 days.

Hunter.io vs. ZeroBounce for email deliverability

A primary differentiator between Hunter and ZeroBounce is its email deliverability tools. While both offer email validation as a primary service, it’s ZeroBounce that provides a platform better dedicated to overall email deliverability.

Hunter.io is most prominently known for its Email Finder service, which allows you to find emails by company or by name. It also offers a Signals service, which helps businesses locate potential prospects by needs.

Comparatively, ZeroBounce also offers an Email Finder*, which lets you search for B2B emails with names or company names.

*Note that ZeroBounce doesn’t store or use processed customer data from email validation for Email Finder results. All data is protected and adheres to global privacy regulations.

Here’s the problem - there are a variety of additional factors that contribute to your ability to reach the inbox. These include email authentication, domain reputation, email blacklists, content quality, and email server configuration.

ZeroBounce offers a high-quality solution for each problem, eliminating the complicated legwork and research involved in each task.
