Clean Data in Hubspot Smart Transfer
Keeping data clean in Hubspot is essential when you move information from other systems. Using Smart Transfer, you can review records, mark empty properties, and choose which fields should be cleared or preserved so your CRM stays reliable.
This guide explains how to use Smart Transfer to mark empty properties, understand cleaning options, and safely apply those changes to your account.
What is Hubspot Smart Transfer?
Smart Transfer is a tool that helps you bring records into your CRM while reviewing and adjusting field values before they are finalized. When a transfer is in progress, you can open individual records, preview property values, and decide whether to keep or clear them.
During this process you will see source values from the connected app and destination values that already exist in your CRM. Smart Transfer makes it easier to prevent outdated or incorrect information from overwriting the fields you rely on.
Accessing Smart Transfer in Hubspot
Before you can clean up data, you need to open the transfer you are working on and access the record review screen.
- Sign in to your CRM account.
- Navigate to the data sync or integration area where Smart Transfer is available.
- Select the transfer job that is currently in progress or recently completed.
- Click into the review step to see the list of records and property mappings.
Once you are in the review mode, you will be able to open specific records and interact with property values, including the tools that mark certain fields as empty.
Why Mark Empty Properties in Hubspot Smart Transfer?
Marking empty properties during a Smart Transfer gives you precise control over which fields should be cleared and which should remain untouched. This is important when the incoming data does not contain a value for a mapped property.
By default, missing values from the source system might be left alone to avoid unintentionally erasing existing information. However, in many cases you want to explicitly clear fields that are no longer relevant. Smart Transfer provides options to do exactly that.
- Prevent old values from lingering in your CRM.
- Reduce confusion for sales, marketing, and service teams.
- Improve segmentation and reporting accuracy.
- Prepare cleaner data for automation and workflows.
How Hubspot Handles Empty Properties in Smart Transfer
When records move through a Smart Transfer, the tool compares property values from your connected app to the existing values in your CRM. If the source property is empty, the system needs instructions about what to do with the field in the destination.
Default behavior for empty properties in Hubspot
By default, if a mapped property in the source app has no value, Smart Transfer does not automatically replace or clear the current field in your CRM. This helps avoid accidental data loss when the absence of data is temporary or unintentional.
However, if you know the empty state is correct for a specific field, you can override the default behavior and mark that property so the existing value will be removed when the transfer is applied.
Cleaning rules for properties in Hubspot Smart Transfer
Smart Transfer uses a small set of cleaning rules to manage how empty properties are handled. These rules can be applied at the property level while you review each record or group of records:
- Keep existing value: Do not change the current field in your CRM when the source is blank.
- Clear value: Explicitly set the destination field to empty when the source is blank.
You select the appropriate rule during the review process so each mapped property behaves the way you expect.
Step-by-Step: Mark Empty Properties in Hubspot Smart Transfer
Use these steps as a general workflow to mark properties as empty while you review records in your transfer job.
- Open the transfer review screen.
From your integration or data sync area, open the Smart Transfer and move to the review stage where you can inspect each record. - Select a record to review.
Click a record to see its property comparison. You will typically see the source data from the connected app on one side and the existing CRM data on the other. - Locate mapped properties.
Find the mapped properties that matter most to your data quality, such as lifecycle stage, owner, status, or custom fields you rely on for segmentation. - Identify empty source values.
Look for properties where the source value is blank. These may display as empty fields, null values, or a specific indicator showing that no data was provided. - Choose to clear or keep values.
For each property with an empty source value, decide whether to keep the existing CRM value or clear it:- If you keep the existing value, no change will be made.
- If you clear the value, the property will be set to empty when the transfer is applied.
- Mark the property as empty.
Use the on-screen controls to mark the property so that the destination field will be cleared. The interface will usually show a checkbox, toggle, or cleaning rule selector that confirms your choice. - Repeat for other properties and records.
Continue through the records in your transfer, marking additional properties as needed. You can focus on high-impact fields first to save time. - Apply the transfer.
After you finish reviewing and marking properties, confirm and run the final step of the transfer. The system will update the destination records according to your selections, including clearing any fields you marked as empty.
Best Practices for Using Hubspot Smart Transfer to Clean Data
To get the most from Smart Transfer when you clean properties, consider these practical tips.
Plan your property strategy in Hubspot
Before running a large transfer, review your property strategy inside the CRM. Identify fields that should never be cleared automatically, like critical identifiers, and properties that can safely be wiped when the source is empty, such as temporary campaign fields or outdated tags.
Test Smart Transfer on a small sample
Start with a limited subset of records and mark empty properties on that sample first. After the transfer runs, verify that the correct values were cleared and that important data was preserved. Once you are confident in the behavior, proceed with a larger batch.
Document your cleaning rules in Hubspot
It helps to document your choices so each team member knows how empty properties should be treated in Smart Transfer. Keep a short reference list that includes:
- Which properties must always keep existing values.
- Which properties can be cleared when the source is empty.
- Any exceptions or special cases for particular integrations.
This documentation improves consistency across future transfers and reduces the chance of accidental data loss.
