Our data

The how & why behind our data.

As a Hunter user, you get access to our unique database that leverages the public web. We analyze millions of websites daily to source professional contact information while fully complying with data protection regulations.

The ethical approach to email outreach.

At Hunter, we want to contribute to a more transparent business environment. We aim to help you run cold email campaigns that comply with data protection regulations and respect the privacy of your recipients.

Our data allows you to be more confident when sending cold emails because you can tell your recipients exactly how you found their contact information.

Committed to data quality.

The accuracy of your contact information can make or break your email outreach, and the tools you use to source your email addresses need to be reliable for you to succeed.

That's why we focus on the accuracy of our Email Finder and Email Verifier. Our goal is to find as many emails as possible without sacrificing the quality of the data.

Synchronized with the entire web.

Building a standard to connect businesses.

Data providers typically compile dozens of often private and undisclosed sources. At Hunter, we believe data should be processed transparently in a manner every stakeholder approves of. To do so, we follow four principles.

Data distributed with Hunter has disclosed public sources.

All the contacts in the Domain Search are returned with information about where and when we found them.

In the Email Finder, we indicate if the result is a guess or if it has public sources. The guessed email addresses are based on the public data available at the domain name level.

Data that no longer has public sources is removed.

After six months, we remove contact or company information that no longer has public sources. Before removing the data, we display the "Removed" label for the data sources that can no longer be found online.

Data subjects have control over their data.

Anyone can easily remove their contact information by claiming their email address. The owner can edit all the fields associated with an email address. In case of deletion, the email address and all related data are removed.

Website owners have control over how we index their pages.
