Nymeria's browser extension enables you to find personal and professional email leads with the click of a button.
It has a nice add-on feature which brings up emails when browsing within LinkedIn. Very handy for recruiters!
Hunter helps you find and verify professional email addresses from domains, companies or a specific professional on the web.
Wr like how Hunter's email extension not only searches the email address of the prospect but also displays the email format of the organization.
