When left unchecked, duplicates reduce trust, cause operational inefficiencies, and hurt the customer experience. Whether the duplicates come from manual imports, third-party integrations, or form submissions without emails, **Koalify** makes identifying and resolving them in HubSpot fast, scalable, and accurate. ### Why Koalify? After installing the **Koalify app from the HubSpot Marketplace**, it automatically generates a set of **custom properties** designed to help you detect and manage duplicates. This field becomes the basis for quickly filtering duplicates and guiding your next action — whether merging, excluding, or reviewing manually. ## Step-by-Step: How to Find and Merge Contact Duplicates in HubSpot ### ✅ Step 1: Create a Filtered View for Duplicates To start reviewing duplicates: 1. Go to **Contacts** in your HubSpot CRM. 2. Click **Create view** or **Add filter**. 3. Set the filter: `Koalify Main Duplicate Properties is any of (Mobile) Phone Number` This will surface all contacts where a duplicate was detected based on their phone number/ 💡 **Tip:** You can expand this view to include: - `Mobile Phone Number` - `WhatsApp Phone Number` - Any **custom phone number field** used in your portal. ![Koalify main duplicate properties on is any of “(Mobile) phone number](https://koalify.io/hs-fs/hubfs/Koalify%20main%20duplicate%20properties%20on%20is%20any%20of%20%E2%80%9C(Mobile)%20phone%20number.png?width=940&height=261&name=Koalify%20main%20duplicate%20properties%20on%20is%20any%20of%20%E2%80%9C(Mobile)%20phone%20number.png) ### 🔄 Step 2: Open the Primary Record and Merge Once your view is ready: 1. **Select the record you want to keep** — usually the one with the most complete data or original source. 2. Look for the **"Contact Duplicates" Koalify card** in the right sidebar. 3. Click **Merge**. That’s it. The duplicate record will be merged into the primary one, and Koalify will retain your preferred data source. ➡️ Learn more about how to merge duplicate HubSpot contacts ## Bonus: Automate Duplicate Merging with HubSpot Workflows Once your rules are defined and working, you can fully automate the merge process using HubSpot workflows and Koalify’s built-in **“Merge Duplicate Contact”** action. ### 🎯 Sample Workflow Enrollment Trigger: - `Koalify Main Duplicate Rules is any of First Name, Last Name and Mobile Phone` - `Koalify Is Primary Duplicate = False` ### ➡️ Action: - `Merge Duplicate Contact` This ensures that **non-primary duplicates are automatically merged into the main record,** saving time, eliminating manual work, and keeping your data clean behind the scenes.   --- ## Final Thoughts: Less Clutter, Better Conversations Cleaning up duplicates isn’t just about neat data. It’s about: - Making sure your sales team doesn’t double-reach - Ensuring accurate campaign reporting - Giving every contact a consistent and personalized experience Want to go deeper?
