How to evaluate a Google Maps email extractor
We do not rank extractors. The useful test is simple: run each on the same search, verify what comes out, and compare.
The test
Pick one search (a category in a city). Run each tool, deduplicate, verify, and record rows with an email, valid share, role share and cost per valid address.
Check the rules too
Confirm the tool and your use stay within the listing and website terms and applicable law. A tool that breaks them is not cheaper once you count the risk.
