Reviews across the web
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.
Full roundup →Prospeo is a newer email finder with a strong G2 profile (4.6 across ~437 reviews) and a reputation for accuracy and low bounce rates, especially on LinkedIn-based workflows. The main friction points in negative reviews are credit consumption on bulk jobs that return few matches, and slow support on billing issues. Note that Prospeo publishes many comparison pages about competitors, so third-party coverage of the space often traces back to its own content.
