Hunter.io reviews
4.5/ 5 · weighted across 1,337 reviews
Hunter.io keeps consistently good scores across G2 (4.4) and Capterra (4.6) and is widely seen as a simple, trustworthy email finder and verifier. The recurring criticism is that it has not kept pace with modern outbound: no phone data, a thin campaigns feature, and mid-pack accuracy in recent community benchmarks. It remains a default pick for straightforward email finding on public web data.
