Studies built from the samples behind our lead lists: the top Google Maps results for one industry in one city, 6,399 times over, across five countries. Each one publishes its method, its caveats and an aggregate CSV you can reuse under CC BY 4.0.
Data study · July–September 2026 data · updated
We checked 65,024 top Google Maps listings for a contact email on their own website and found one for 63%: from 56% in the US to 81% in Germany. Also by industry, with website presence, free-webmail shares, review counts and star ratings.
Every figure is an aggregate over samples we harvested ourselves, and the studies and their CSVs carry no business-level rows. The samples themselves are browsable, with emails masked, as lead lists by industry and city. Questions about the data: [email protected].
