BounceProof

BounceProof provides an email verification service that can be invoked directly from Google Sheets, allowing users to filter out hard bounces, catch‑all domains, disposable addresses, and known spam traps before sending campaigns. The tool reports validation results alongside the original data, enabling quick cleanup of large address lists without exporting to external applications.

It is aimed at teams that manage email outreach, such as sales, marketing, and data‑ops groups, who need a shared, real‑time view of which addresses are safe to use. Credits can be shared across members, and the system tracks validation history and progress, sending alerts when checks complete.

The service emphasizes speed and accuracy, claiming a validation rate faster than many alternatives and an accuracy level of 98.5 % for identifying risky emails that other validators may miss. It operates on a pay‑as‑you‑go model without subscription commitments.
