The Bulk Domain Search lets you find email addresses from a list of companies or domain names in bulk. All you need to start using it is a list of domains or companies.

It leverages Hunter’s data by surfacing all emails we know about for each domain on the list. To make your life easier, the email addresses are enriched with additional information like full names, types of email addresses (generic vs. personal), and departments (marketing, IT, HR, and so on.)

You can test it by looking up a specific domain with the regular Domain Search.

The Domain Search uses email addresses that were found publicly on the web. Each email address comes with a confidence score that is calculated depending on the quality of the sources, SMTP verifications, and other data points. On rare occasions, the surfaced email addresses may no longer be relevant, particularly for industries with high employee turnover.

No, the Bulk Domain Search requires a premium plan. You can choose the right plan for you, depending on the number of credits you need.

However, you can try out the Bulk Domain Search before upgrading your account. Upload your CSV to see how many email addresses we find, the average data quality, how many credits you'll need, and a preview of the data.
