Why people look
Usually because knowing an address is not the same as knowing who to write to or what to say, and Hunter starts from the domain, not the buyer.
What Buzzlist does differently
One flat price per account. Free, then $199, $499 or $1,499 a month. Month to month. 100 contacts every month, for as long as you like. No card, no demo, no clock.
The bigger difference is what happens after the search. Buzz picks the people with a reason each, writes four emails per person from their website, and builds the Sales Brief. Sending is coming. The research and the writing stay in the same account, so nothing moves to another tool.
Where Hunter may still suit you
Hunter's domain search and verifier are fast when you already know the company and the name. Buzzlist is for when you do not yet know who.
