Emergency Unmerge is the only HubSpot app that reverses merges already performed through HubSpot's native merge function.

When contacts, companies, or deals are accidentally merged in HubSpot, the original records are destroyed. Properties are overwritten, associations are tangled, and activities from two separate records land on one. HubSpot has no undo button. HubSpot support cannot reverse it. Manual reconstruction can take days or weeks for complex records.

Emergency Unmerge solves this in under 5 minutes, working directly inside HubSpot as a middle or right sidebar card. Bulk unmerge via HubSpot Segments or CSV upload within the Account Portal gives you full control over which records you unmerge and how properties and associations are reassigned.

How it works

Open any merged record and click Scan. The scan is always free and shows you exactly what happened, how complex the record is, and what it will cost to fix. Click Reconstruct and the app uses AI to analyze every property's revision history, every association, and every activity to determine which data belonged to which original record. Review the full reconstruction with per-field confidence scores before anything changes in your CRM. Once confirmed, click Execute and the app creates the restored record with all original properties, associations, and activities in the correct place.

What it handles

• Contacts, companies, and deals

• Chain merges (A into B into C) with selective undo of specific merge events

• Merges from any source: manual, bulk operations, third-party dedup tools, Salesforce sync, or API

• All HubSpot tiers: Free, Starter, Professional, and Enterprise

• Per-property confidence scoring on every reconstructed field

• Post-execution property editor and association editor for quick corrections

• Recovery snapshots on every operation

AI-powered reconstruction

Emergency Unmerge uses intelligent model routing to balance speed, accuracy, and cost. Simple records (100 items or fewer) use a faster AI model. Complex records (over 100 items) automatically route to a more capable model. If initial confidence falls below 80%, the system retries with the more powerful model for maximum accuracy. Extended thinking budgets scale with record complexity, from 3,000 tokens for simple records up to 16,000 tokens for the most complex.

Merge audit

Not sure if a merge was a mistake? Run a Merge Audit before committing to a full unmerge. The audit analyzes the merged record and flags whether the merge was correct or suspicious, all at 10% of the standard credit cost (minimum 2 credits). If the audit reveals a problem, bridge directly to a full reconstruction at 75% of the regular price since the scan data is reused.

Bulk unmerge

Scan up to 10,000 records from a CSV or HubSpot list to find every merged record in your CRM. Free and read-only: it detects merges, classifies each one's type and complexity, estimates the unmerge cost, and exports a CSV report. Supports HubSpot Merge History exports and standard view/segment exports. Bulk unmerges are then run as a guided recovery with our team.

Safe Merge integration

Records protected by Safe Merge snapshots can be unmerged instantly at no credit cost. Emergency Unmerge detects snapshot protection automatically and offers one-click undo when pre-merge snapshots exist. No AI reconstruction needed.

Pricing

No subscription. Pay only for what you use. The scan is always free, and you see the exact credit cost before committing. Failed operations are automatically refunded.

Credit packages:

• 100 credits: $4.99 ($0.05 per credit)

• 250 credits: $9.99 ($0.04 per credit, save 20%)

• 500 credits: $19.99 ($0.04 per credit, save 20%)

Credits scale with record complexity based on total associations and activities:

Chain merges add a 100% surcharge to cover the additional AI analysis. Merge audits cost 10% of the base credit rate (minimum 2 credits). New portals receive 50 free credits on install.

Important note on HubSpot API limitations

Due to HubSpot API limitations, Emergency Unmerge creates new records with new Record IDs rather than restoring the original merged record. HubSpot-generated read-only fields (such as Create Date and analytics source data) on new records will reflect the new record's creation date, not the original.

Emergency Unmerge automatically preserves the original values in a dedicated custom property group called "Emergency Unmerge" on each new record, including the original Create Date, original Record ID, and a complete JSON backup of all read-only fields.
