HubSpot's duplicate management tool can now reject more than fifty suggested duplicate pairs at a time, in a public beta for Data Hub Professional and Enterprise. We cover how the duplicate model picks pairs and its default similarity cutoff, the filters you can use to isolate false matches, the select all flow, who has access, how Refine suggestions differs, what rejecting does, the View history undo and its limits, and why bulk merging isn't part of this yet. First thing to try: sample a low-similarity range, then reject only the range you trust.

Who it's for: HubSpot admins and marketing or RevOps teams on Data Hub Professional or Enterprise who clean up duplicate contacts and companies.

Our research first covered this on November 4, 2026. Here's where it stands as of our Nov 4, 2026 check. HubSpot's in-app product updates, last updated Nov 4, 2026, list it as a public beta for Data Hub Professional and Enterprise, with no release date, so we date it to that update. HubSpot's help article on duplicates (updated Oct 23, 2026) covers checkbox rejects, filters, and a fourteen-day undo window; we couldn't confirm whether that window applies the same way to pairs rejected through select all. Our write-up's navigation path and its advice on similarity thresholds aren't in HubSpot's sources.
