This little free tool saved me at least 2 hours.
Recently I had a little-used out-of-warrantee product I wanted fixed or replaced by the vendor. After calling customer service, and waiting on hold for a supervisor for over 40 minutes, the supervisor, not surprisingly, told me it was out of warrantee and made me an offer I could and did refuse.
It seemed worth an escalation to people with broader more strategic views of customer retention. I had the names of the CEO and the person in charge of the product line, but was completely unsuccessful in securing their email address.
Then I stumbled upon an invaluable tool. Type the company url (e.g. “google.com”; “peta.org” etc…)into Email Hunter then look right below the search box, above the list of emails. It will tell you the PATTERN for emails in that organization.
This is about as much as you get in the free version (which should be enough for almost anyone with a product complaint or trying to reach a particular individual).
In the paid versions, you *may* be able to find actual email addresses for specific people (you do not have to guess based on the pattern. And you can verify if the email is correct (which free users can do by simply sending it and seeing if it is returned as undeliverable).
