Top Deduplication Strategies for Salesforce and HubSpot Contacts

Published by:

Discover expert strategies for deduplicating Salesforce and HubSpot contacts. Avoid sync issues, improve data quality, and streamline your CRM ecosystem with these proven methods.

Maintaining a clean CRM database is critical — especially when you're syncing contact data between Salesforce and HubSpot. Without proper deduplication, you're likely to face misaligned records, duplicate outreach, and unreliable reporting. If your business relies on both platforms, understanding how to effectively deduplicate contacts is essential for CRM health.

Why Deduplication Matters for Salesforce and HubSpot Contacts

As contacts move between HubSpot and Salesforce, inconsistencies arise:

  • Multiple versions of a contact: The same individual may appear twice with different details.
  • Disconnected customer journeys: Sales and marketing teams may act on outdated or incorrect data.
  • Wasted time and resources: Your team spends time managing duplicates instead of closing deals.

Deduplication ensures your contacts are accurate, unified, and useful across both platforms.

Challenges in Cross-Platform Deduplication

  • Inconsistent identifiers: HubSpot uses email for deduplication, while Salesforce may rely on phone numbers, full names, or custom fields.
  • Manual merges break sync: Merging contacts manually in Salesforce can break the integration with HubSpot if done improperly.
  • Scalability: Manual deduplication is not feasible when dealing with large datasets across both platforms.

Effective Deduplication Strategies

  • Standardize key fields: Use consistent formatting for emails, phone numbers, and names in both platforms.
  • Define a universal ID: Implement a shared unique identifier (like a customer ID) to sync records accurately.
  • Use automated tools: Platforms like getnucleus.io offer cross-platform deduplication and syncing, removing the manual work.
  • Set up deduplication rules: Establish rules to detect and prevent duplicate contact creation at the source.
  • Run periodic cleanups: Audit your contact database monthly to find and fix lingering duplicates.
