1. Getting Started

1Install Emergency Unmerge from the HubSpot App Marketplace. This takes about 30 seconds and requires Super Admin permissions.

2Authorize the app: HubSpot will prompt you to grant CRM data access via OAuth. Emergency Unmerge needs read/write access to contacts, companies, deals, and their associated activities. Check the acknowledgment checkbox and click "Connect app".

Once installed, a sidebar card labeled "Emergency Unmerge" appears on every contact, company, and deal record in your HubSpot portal.

Tip: No subscription is required. You only pay when you purchase credits, and credits never expire.

For a visual walkthrough with demo videos, see the Setup Guide.

Adding Cards to Record Pages

After installation, add the Emergency Unmerge cards to your record page layouts. Repeat these steps for Contacts, Companies, and Deals:

  1. Go to Settings → Data Management → Objects and select the object type.
  2. In the record page editor, create a new tab named "Emergency Unmerge".
  3. Click "Add card" and search for "Unmerge" in the card library.
  4. Add the Emergency Unmerge Tab card to the middle column.
  5. Add the Emergency Unmerge sidebar card to the right column.
  6. Click "Save and exit".
HubSpot Settings - Data Management - Objects
Navigate to Settings → Data Management → Objects to customize record page layouts.
Creating a new Emergency Unmerge tab on the Company record page
Create a new tab named "Emergency Unmerge" and click "Add card" to add cards.

2. Scanning a Merged Record

Navigate to a record that was created by an accidental merge. The Emergency Unmerge sidebar card will appear on the record page.

  1. Click "Scan Record" in the sidebar card.
  2. The scan is completely free: no credits are charged.
  3. Within seconds, the scan returns:
    • Whether a merge was detected
    • Number of properties, associations, and activities involved
    • Complexity assessment (simple vs. complex)
    • Exact credit cost for reconstruction

If a chain merge is detected (the record was merged multiple times), the scan will show how many merge events occurred.

3. Reconstruction

After reviewing the scan results and purchasing credits (if needed), click "Generate Reconstruction Plan".

The system (Anthropic's Claude) analyzes:

Reconstruction typically takes 1-2 minutes depending on complexity.

Reconstruction plan with confidence scores and property assignments
After reconstruction, review every property assignment with confidence scores. Use the property history dropdown to pick an alternative value for any field.

Important: Credits are charged when reconstruction begins. If reconstruction fails (API error, timeout), credits are automatically refunded.

4. Reviewing the Reconstruction

After reconstruction, you enter the Review step. Here you can inspect the reconstruction before anything touches your CRM.

Tip: If you leave the page during review, you can resume the operation from your account history page. No data is lost.

5. Executing the Unmerge

Once you're satisfied with the reconstruction, click "Execute Unmerge".

Important: Review carefully before executing. Executing will create new records in your HubSpot CRM. Due to HubSpot API limitations, we cannot restore the original merged record. Instead, a brand-new record is created with a different Record ID and new HubSpot-generated fields such as Create Date. Recovery snapshots are saved automatically, and the Property Editor lets you correct any writable fields after execution.

Where are the original read-only values? Emergency Unmerge automatically saves all unwritable HubSpot fields in a custom property group called "Emergency Unmerge" on each new record. Key properties include:

You can view these properties on any unmerged record under the "Emergency Unmerge" property group in HubSpot.

During execution, Emergency Unmerge:

  1. Captures a pre-execution snapshot of the current record state (all properties + associations)
  2. Creates a new record with the secondary/restored properties (this record will have a new HubSpot Record ID)
  3. Saves original read-only values (Create Date, Record ID, analytics source, etc.) to the "Emergency Unmerge" property group
  4. Reassigns associations (contacts, companies, deals, activities) to the correct records
  5. Sets metadata properties on both records (unmerge date, original ID, details)
  6. Captures a post-execution snapshot of all affected records

6. Post-Execution Property Editor

If the reconstruction got a property wrong - or you just want to change a value - use the Property Editor on your account history page.

  1. Go to your account dashboard
  2. Find the completed operation in the history table
  3. Click "Edit Properties" in the actions column
  4. A modal opens showing every property for each record:
    • Properties with multiple historical values show a dropdown with all past values, timestamps, and sources
    • Properties with a single value show the current value with an "Edit" link for manual entry
  5. Select the correct value from the dropdown and click "Save"
  6. The value is written directly to HubSpot - no credits charged for corrections

Tip: Use the search bar at the top of the property editor to quickly filter by property name or label.

7. Association Editor

After executing an unmerge, you may need to reassign associations between the separated records. The Association Editor provides full control over associations on both records.

  1. Go to your account dashboard
  2. Find the completed operation in the history table
  3. Click "Associations" in the actions column
  4. The editor shows all current associations on both records (contacts, companies, deals, notes, tasks, calls, emails, meetings)
  5. For each association, you can:
    • Move: Transfer the association from one record to the other
    • Add: Create a new association on either record
    • Remove: Delete an association from a record

The editor also shows the AI's original recommended assignment for each association, so you can compare what the system suggested with what is currently live in HubSpot.

Tip: No credits are charged for association changes. Move, add, and remove as many associations as you need after execution.

8. Analysis Export

Download the full reconstruction analysis as a JSON file for compliance, auditing, or manual verification.

The export includes:

To download:

  1. Go to your account history
  2. Find any operation that has completed reconstruction (or later)
  3. Click "Download Analysis" in the actions column
  4. A JSON file downloads with the complete analysis data

Tip: The analysis export is available after reconstruction completes, even before execution. Use it to review the AI's reasoning in detail before committing to changes.

9. Operation History & Credit Ledger

Your account dashboard shows a complete history of all operations with:

Below the operations table, the Credit Transaction Ledger shows every credit transaction: purchases, deductions, and refunds with dates and descriptions.

10. Recovery Snapshots

Every execution automatically captures JSON snapshots of all affected records - both before and after the unmerge. These include every property and association on each record.

To download snapshots:

  1. Go to your account history
  2. Find the completed operation
  3. Click "Snapshots" in the actions column
  4. A JSON file downloads containing the full pre/post record states

Note: Recovery snapshots are a courtesy for developer-assisted manual restoration. They are NOT an automatic undo feature. Restoring records from snapshots requires manual effort using the HubSpot API.

11. Chain Merges

A chain merge happens when a record was merged multiple times (e.g., A merged into B, then B merged into C). Emergency Unmerge detects chain merges automatically during the scan.

Chain merges may require more credits due to increased complexity.

12. Bulk Scan Overview

The Free Bulk Scan lets you scan up to 10,000 records at once by uploading a CSV file or selecting a HubSpot List/Segment. It detects every merged record in your set, classifies merge type and complexity, and estimates the unmerge cost for each one. The scan is completely free and makes no changes to your CRM.

Once you have the scan results and know the scope, you can download the full findings as a CSV. If you decide to proceed with unmerging, the actual bulk unmerge is handled as a guided recovery: we run the rebuild with you so the reconstruction order and re-association are done safely. See Section 14: Guided Bulk Recovery for how to start.

Supported Sources

The Free Bulk Scan accepts three sources:

For CSV uploads, the system auto-detects the format. For HubSpot Lists, select the list from the dropdown and click "Load Records."

What the Scan Returns

For each record in your set, the scan checks merge history and returns:

Records where no merge is detected are marked and excluded from the cost estimate. The scan summary shows the total count of merged records found and the total estimated cost across the set.

Downloading the CSV Report

After the scan completes, download the results as a CSV file from your account dashboard. The CSV includes per-record details: merge detection status, complexity, and estimated unmerge cost. Share it with stakeholders or use it to prioritize which records to recover first.

Free and read-only: The Free Bulk Scan never modifies your CRM. No credits are charged for scanning. For datasets larger than 10,000 records, split your CSV into multiple files or create multiple HubSpot Lists and run separate scans.

13. Free Bulk Scan

The Free Bulk Scan is a read-only tool for assessing the scope of a merge problem across many records at once. It detects every merged record in your input set, classifies the merge type and complexity, and estimates the cost to unmerge each one. No changes are made to your CRM and no credits are charged.

Use the Free Bulk Scan when you want to:

Start a Free Bulk Scan from the Bulk Scan section on your account dashboard. Upload a CSV or select a HubSpot List, choose the object type (contacts or companies), and click "Start Scan." See Section 12 for supported sources and what the scan returns.

Scan Report (CSV Download)

After the scan completes, download the results as a CSV from your account dashboard. The report includes per-record details: merge detection status, merge type, complexity classification, and estimated unmerge cost. Use it to review scope and share findings with stakeholders before deciding how to proceed.

Ready to unmerge? Once you have your scan results, contact us to start a guided bulk recovery. We run the bulk unmerge with you so the rebuild order and re-association are handled safely. See Section 14 for details.

14. Guided Bulk Recovery

Once your Free Bulk Scan is complete and you know the scope, the next step is a guided bulk recovery. We run the bulk unmerge with you so the reconstruction order and re-association logic are handled safely from start to finish.

Bulk unmerge involves rebuilding many records in a specific sequence, re-attaching associations correctly, and verifying results at each phase. Doing this safely at scale requires the right order of operations and checks that go beyond what a self-serve tool can guarantee. A guided recovery ensures none of that is left to chance.

How to Start

  1. Complete a Free Bulk Scan and download the scan report
  2. Review the report to confirm scope and decide which records to recover
  3. Contact us at joshua@thirdspaced.com or book a call to start a guided recovery engagement
  4. We scope the job with you, agree on the approach, and run the bulk unmerge together

Scan first, then decide: The Free Bulk Scan gives you a full picture of scope and cost before any commitment. Bring the scan report to your first call and we can scope the recovery from there.

15. Credits & Billing

Credit Packages

Tip: The free scan tells you the exact credit cost before you buy. Use per-credit purchasing to buy exactly the number you need. No waste, no overspending.

How Credits Are Used
