Hunter Signals Feature Email Notification
This feature is awesome if you are a job seeker or just looking for new clients. It saves much time otherwise spent on manual research for companies that received funding or have job openings.
Domain Search
Domain Search is the bread-and-butter of Hunter – and is probably the feature you will use the most. It lets you find all email addresses related to a specific domain. Hunter finds these email addresses by scraping public mentions of the email address, either on the searched domain or other websites.
In 2024, Hunter expanded their data ingest pipelines and data sources, leading to more than double the total volume of profiles available in Hunter. The total increase was 211% from January to October. In 2025, Hunter’s team planned expansions that should lead to an increase between 50%-100% of total available profiles. All profiles in Hunter are validated. While profiles with accept-all/catch-all email addresses are available in Hunter, these are not included in the data count.

For Domain Search, this improvement means there will be 60% more profiles that include a job title, location, and LinkedIn profile URL.
Keep in mind that Hunter won’t scrape social media profiles for emails, which can limit the number of emails found associated with a certain company.
You can search by typing an individual domain or upload a list of domains to
