Exploration is free, and that changed how I buy data. I sized six segments before spending a single credit and found my real universe was 135 people, not the 300 I had assumed. Filtering for verified emails upfront cut my list from 77 to 33, and all 33 were in the right role. It also found a company I had already given up on after checking two public databases.

The counters contradicted each other once: one search reported 17 records matching my filters but 33 available, when the first number should never be lower. I trusted the larger one and it was right, but I nearly stopped mid-workflow. Portuguese keywords also returned nothing useful in website filters, so non-English markets need the standardized autocomplete values. Review collected by and hosted on G2.com.
