Real-time duplicate monitoring for HubSpot custom fields requires a live connection that HubSpot’s native tools simply can’t provide. Custom properties fall outside HubSpot’s standard deduplication capabilities, leaving you blind to duplicate issues until they pile up.
Here’s how to build a real-time monitoring system that catches duplicates the moment they appear in your custom fields.
Build continuous duplicate monitoring using Coefficient
Coefficient establishes a continuous data sync between HubSpot and Google Sheets, giving you near real-time monitoring capabilities that HubSpot can’t match for custom properties.
How to make it work
Step 1. Connect and configure your data import.
Set up Coefficient to import your HubSpot objects with the specific custom fields you want to monitor. Configure automatic refresh intervals as frequent as hourly to ensure you catch new duplicates quickly.
Step 2. Build detection logic with formulas.
Create duplicate detection formulas using Google Sheets functions like =COUNTIFS($C:$C,C2,$A:$A,””<>“”&A2) to find duplicates while excluding the current row. For complex scenarios, use array formulas to detect duplicates across multiple custom properties simultaneously.
Step 3. Set up real-time visual indicators.
Implement conditional formatting rules that automatically highlight duplicate values as they appear in your refreshed data. Use different colors to distinguish between new duplicates and existing ones, making it easy to spot fresh issues.
Step 4. Create an automated monitoring dashboard.
Build a summary section that shows total duplicate count by custom field, recently added duplicates using timestamp tracking, and duplicate percentage rates for overall data quality metrics. This gives you a bird’s-eye view of your data health.
Step 5. Configure instant alerts.
Use Coefficient’s alert functionality to trigger notifications when new duplicates are detected, when duplicate counts exceed your threshold values, or when specific high-priority custom field values get duplicated.
Get proactive about duplicate management
This setup provides continuous monitoring capabilities that surpass HubSpot’s standard property limitations, letting you manage duplicates for business-critical custom identifiers before they become problems. Start building your real-time monitoring system today.
