How Emergency Unmerge Reverses HubSpot Merges

Emergency Unmerge reverses HubSpot merges in four steps: install from the HubSpot Marketplace (30 seconds), scan the merged record for free, reconstruct the original records using property history analysis, then review and execute. The entire process takes about 5 minutes. No subscription required — starting at $4.99.

Scan the Merged Record (Free)

Navigate to the merged record in HubSpot. Click "Scan Record" in the Emergency Unmerge sidebar card. The scan is always free — no credits required.

The scan detects merge history, analyzes complexity, and provides:

✓ Whether the record has been merged (and how many times)
✓ Complexity assessment (simple, moderate, or complex)
✓ Exact credit cost for reconstruction
✓ Which records were merged (for chain merges)

If the record has no merge history, you pay nothing. The scan tells you everything before you commit.

Reconstruct the Original Records

Purchase credits and click "Generate Reconstruction Plan". The system performs a deep forensic analysis to rebuild the original records:

✓ Property history analysis: Examines HubSpot's version history for every property to determine which values belong to which original record
✓ Timestamp forensics: Uses creation dates, modification timestamps, and merge event timing to resolve ownership
✓ Association recovery: Reconstructs all associations — contacts, companies, deals, notes, emails, tasks, and calls — and assigns them to the correct records
✓ Email forensics: Analyzes email addresses and communication patterns to determine record identity

Reconstruction takes 1–2 minutes depending on complexity. Works on merges from minutes ago or months ago.

Review and Execute

Review both reconstructed records side-by-side in the full-screen tab view. Every field shows:

✓ The reconstructed value for Record A and Record B
✓ A confidence score with reasoning
✓ "Swap All" option if primary and secondary are reversed

Nothing touches your CRM until you click Execute. Your credits purchase the analysis — you always receive the full reconstruction as a downloadable JSON report, even if you choose not to execute.

Click "Execute Unmerge" to recreate the separated records in HubSpot with all properties, associations, and metadata restored.

Correct Any Field (If Needed)

After execution, visit your account history page to use the built-in Property Editor. If the reconstruction got a field wrong, the editor shows every historical value in a dropdown — pick the right one and save it directly to HubSpot. Every execution also captures pre and post JSON snapshots you can download anytime.

Important: What to Know Before You Start

* Due to HubSpot API limitations, unmerging creates new records with new Record IDs rather than restoring the originals. Original values are preserved in the "Emergency Unmerge" property group.
* Results are probabilistic. Simple merges typically achieve 90%+ confidence. Complex records may be lower. Always review before executing.
* The sooner you act after a merge, the more complete the property history data available for reconstruction.
* Credits purchase the analysis. You receive the full report even if you don't execute. See FAQ for details.
