Keep Nutshell CRM clutter-free: merge duplicate contacts, prevent errors, and improve your sales process.
Published on September 17, 2025
Duplicate contacts are one of the most common and frustrating problems in any CRM. They clutter your database, skew your reports, and can lead to embarrassing mix-ups, like having two different sales reps contact the same prospect. At Add to CRM, we know that clean data is the foundation of an efficient sales process. In this guide, we'll walk you through how to clean up existing duplicates in Nutshell CRM and, more importantly, how to prevent them from ever being created.
Messy data isn't just an annoyance; it actively undermines your sales efforts. Duplicate records can lead to:
Duplicates often stem from simple mistakes: manual entry errors, multiple data imports, or inconsistent formatting. Luckily, Nutshell CRM provides tools to fix this.
Nutshell CRM has built-in features to help you spot potential duplicates before they get out of hand.
Once you've identified a duplicate, merging it is straightforward. Here’s how to merge two records from a contact's page:

If you have a larger cleanup project, you can merge records in bulk directly from the list view.
For leads, you can merge up to three at a time. The merged leads will be marked with a "cancelled-merged" status, and all their associated information will be consolidated into the master lead.


LinkNut is a Chrome extension that finds verified contact information from LinkedIn and adds standardized data to Nutshell CRM. While Nutshell's merging tools are great for cleanup, the best strategy is prevention. Our tool helps you stop duplicates before they start by ensuring the data you add to your CRM is clean, verified, and consistently formatted from the very beginning. It eliminates the manual data entry errors that cause most duplicate issues.
Think about the time your team spends dealing with data issues. Merging duplicates is a reactive process that takes you away from revenue-generating activities. By starting with clean data, you avoid this cleanup cycle entirely. Using a tool like LinkNut is a proactive measure that saves countless hours down the road, ensuring your CRM remains a reliable source of truth.
It only takes a minute to get started:
One of the most powerful features of LinkNut is its ability to check for existing contacts in real-time. While you're browsing LinkedIn, our extension automatically cross-references the profile with your Nutshell CRM database. If the person is already in your CRM, we'll let you know. This simple check is your first line of defense against creating an accidental duplicate.
When LinkNut identifies that a contact already exists, it gives you an opportunity to enrich the record instead of creating a new one. You can easily update the existing contact in Nutshell CRM with the latest information from their LinkedIn profile, such as a new job title or company. This keeps your data fresh, accurate, and complete.
This real-time check transforms your prospecting workflow. You no longer have to switch tabs to see if a contact exists. You can see it directly on LinkedIn, preventing duplicates at the source and ensuring your team is always working with the most current information.
Beyond using the right tools, establishing good habits is key to maintaining a clean CRM.
While Nutshell CRM offers solid tools for merging duplicates, the most effective strategy is to prevent them from being created in the first place. A clean CRM is an efficient CRM. By adopting a proactive approach with tools like LinkNut, you can stop wasting time on data cleanup and focus on what truly matters: building relationships and closing deals.
