Merge and prevent duplicate contacts in Insightly. Use LinkSight to add clean, verified LinkedIn leads and keep your CRM accurate.
Published on September 12, 2025
Duplicate contacts are one of the most common and frustrating problems in any CRM. They clutter your database, skew your reporting, and can lead to embarrassing mix-ups where multiple reps contact the same prospect. At Add to CRM, we know that a clean CRM is the foundation of an efficient sales process. This guide will walk you through exactly how to find and merge duplicates in Insightly. More importantly, we'll show you how to prevent them from happening in the first place.
Duplicate records aren't just a minor annoyance; they actively undermine your sales efforts. They often arise from simple mistakes like manual entry errors, inconsistent data formats during imports, or team members adding contacts without checking for existing entries.
Here’s how they cause damage:
Insightly provides a built-in tool to help you track down duplicates. The primary feature for this is called SmartMerge, which scans your records for potential matches.
Insightly's duplicate detection primarily looks for records with similar-sounding or similarly spelled names for contacts, leads, and organizations. You can initiate a scan from the main page of any of these record types. While this tool is great for catching obvious duplicates, it might miss entries where the names are different but the email or phone number is the same. For those cases, a manual search by email or phone is a good backup strategy.
Once you've identified potential duplicates, merging them is straightforward. Here’s how to do it for contacts, leads, or organizations in Insightly:



If you have a large number of duplicates, you can use Insightly's SmartMerge feature to manage them more efficiently. From the Leads, Contacts, or Organizations tab, click the three-dot menu and select "Find Duplicates with SmartMerge." Insightly will run a full analysis and present you with a list of potential duplicate groups. You can then work through this list, selecting the records in each group to review and merge, which is much faster than finding them one by one.
LinkSight is a Chrome extension that finds verified contact information from LinkedIn and adds standardized data to Insightly. While merging is a necessary cleanup task, prevention is a far better strategy. The single biggest cause of duplicates is manual data entry, and our tool is designed to eliminate it.
By automating the process of adding new leads, LinkSight ensures that every new contact is created with clean, standardized, and verified information, drastically reducing the chances of creating a duplicate from the start.
Think about the time your team spends on data cleanup. It's a reactive, never-ending cycle of finding and fixing errors. A proactive approach saves countless hours. Instead of spending time merging records, your team can focus on selling. By starting with clean data from LinkSight, you prevent the problem at its source, saving an average of four hours per week on administrative tasks.
Getting started is simple and takes just a few minutes:
One of the most powerful features of LinkSight is its ability to check for duplicates in real-time, right on LinkedIn. When you view a person's LinkedIn profile, our extension automatically checks if they already exist in your Insightly CRM. This simple check is your first line of defense against creating a duplicate record.
If a contact is already in your CRM, LinkSight doesn't just stop you from creating a duplicate—it helps you make the existing record better. You can easily update the contact's information with their latest job title, company, or other details from their LinkedIn profile. This ensures your data is not only clean but also current, all without creating a new, conflicting entry.
This real-time check transforms your prospecting workflow. Your team no longer has to switch tabs to search your CRM before adding a new person. LinkSight highlights existing contacts directly on the LinkedIn page, preventing accidental duplicates and ensuring every team member works from the same, accurate information.
Beyond using a tool like LinkSight, here are a few best practices to maintain a clean database:
Managing duplicates in Insightly is a critical task for any sales team, and the SmartMerge feature provides a solid tool for cleanup. However, the most effective strategy is always prevention. By building your CRM with clean, verified, and standardized data from the start, you eliminate the problem before it begins.
