With Hunter for Firefox, you can immediately find who to contact when you visit a website.
<strong>★ Domain Search</strong>
The Domain Search is the most powerful email-finding tool of its kind. Click the icon in Firefox to find all the email addresses related to the website you're visiting. It includes the most common email pattern used, department filters and the public sources.
The email addresses are marked verified or returned with confidence scores. If an email address is not verified yet, click "Verify email" next to it.
<strong>★ Email Finder</strong>
If you already know the name of the person you would like to contact, type it in the search field. The Email Finder will return the found email address along with a confidence score and sources.
<strong>★ Lists and sequences</strong>
Click "Save" next to a person to add this lead to a list, then add them to one of your Hunter sequences right from the extension. You can also sync your leads to Salesforce, HubSpot, Pipedrive, Zoho and more than a hundred other CRMs and applications.
