What is Managing and Merging Duplicate Contacts?
Managing and merging duplicate contacts helps keep one accurate contact profile for each person in your CRM. When duplicate records exist, you can combine them into one master record while reviewing key details such as email, phone, business name, tags, conversations, and other contact data.
A master record is the contact profile that remains after the merge. Some information from duplicate records can be retained or combined, while conflicting fields may default to the selected master record unless a different value is chosen during review.
Key Benefits of Managing and Merging Duplicate Contacts
- Cleaner CRM data: Keep one accurate profile for each contact instead of multiple duplicate records.
- Better communication history: Combine relevant conversations, notes, tasks, opportunities, and tags into one contact record.
- More accurate reporting: Reduce duplicate records that may skew contact counts, campaign results, and pipeline visibility.
- Faster contact management: Use search or the Manage Duplicates tool to quickly find and review possible duplicate records.
- Improved team visibility: Help users work from the same contact profile instead of splitting updates across duplicates.
Best Practices
Run duplicate scans periodically to keep your CRM clean.
Always review field conflicts before merging.
Use the Reject option only when you’re sure a record isn’t a duplicate.
Encourage your team to standardize data entry to prevent future duplicates.
How to Manually Merge from the Contacts List
Manual merge is useful when you already know which contact records are duplicates. You can search for the records, select them from the Contacts table, and merge them into one profile.
- Navigate to Contacts > Smart Lists.

- Use the Search Contacts box to find possible duplicate contacts.
- Search by available contact details such as:
- Name
- Business name
- Tags
- Phone
- You can also search manually from the smart list.

- Select the contacts you want to merge.
- Click More from the top action bar.
- Select Merge.

- In the Merge Contacts window, choose the contact that should remain as the Master record.
- Review fields with different values.

- Review All Fields and select the values you want to keep, such as the primary email, phone number, or business name and more.
- Click Merge Contacts.
