Clean up your CRM data fast with Nutshell’s Duplicate cleanup!

Duplicate contacts are one of those problems that creep up slowly and then suddenly feel impossible to fix. Existing duplicate filters can tell you that you had hundreds — or thousands — of potential duplicates, but it couldn’t group them, couldn’t tell you which contact should win, and left you to deal with each one manually. For a list of any real size, that’s not a solution.

We built a bulk deduplication tool to actually solve it. You can now enter a dedicated cleanup mode from your people and companies lists, review every identified duplicate pair, and merge them — one at a time or all at once.

What is Nutshell’s Duplicate cleanup?

Duplicate cleanup is a dedicated cleanup tool in Nutshell, accessible directly from your people and companies lists. Nutshell scans your data and groups potential duplicates — contacts that share the same name, primary email address, or primary phone number — and surfaces them in one focused view.

From there, you decide how to handle them. Review and merge pairs one by one, or let Nutshell auto-merge everything it found in one shot. Either way, every merge is logged in the timeline so you always have a record of what changed.

What can I do with Duplicate cleanup?

Find all your potential duplicates automatically

Enter Manage duplicates mode from your people or companies list and Nutshell does the detection work for you. Duplicates are identified by exact matches on name, primary email, or primary phone number, and grouped so you can see the full picture — not just a long unsorted list of possible matches.

Merge one at a time or all at once

If you want to review before committing, a card-style UI walks you through each duplicate pair so you can confirm each merge individually. If you trust the matches and just want your data clean, use Auto-merge to handle everything in a single action. For large datasets, that’s the difference between hours of manual work and a few clicks.

Keep a complete record of every merge

Every merge — whether reviewed individually or run in bulk — appears in the timeline, so there’s always an audit trail. Nutshell also stores a record of which contacts were merged in each operation, so nothing disappears without a trace.

How do I get started?

Duplicate cleanup is available on all Nutshell plans. Open your people or companies list and look for the button to “Manage duplicates”. Nutshell will do the scan and show you what it found. You can also start by going to Settings → Data → Duplicates.
