Why people look
Usually because building the workflow is a job in itself, credits run down with every step, and nothing gets found or written until you have built it.
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 Clay may still suit you
Clay can chain dozens of data providers and custom steps. If you want to build your own enrichment machine and have the time, it is the tool for that.
