How to Fix Red Underlined Property Values in Hubspot

When you see a property value underlined in red inside Hubspot, it means the data entered does not meet the rules of that field. Understanding why this happens and how to fix it will help you keep your CRM clean and prevent errors when saving records.

This guide walks you through what the red underline means, why it appears, and the exact steps to resolve it directly in your CRM settings.

What the Red Underline Means in Hubspot

In many record views, Hubspot highlights invalid or incomplete entries by placing a thin red underline beneath the property value. This is a validation warning, not just a cosmetic highlight. It indicates that the value does not match the requirements defined for that specific property.

Those requirements are controlled by the validation settings for that property. When the value breaks one of those rules, the interface shows the red underline and may prevent you from saving changes until the issue is fixed.

Main Reasons Property Values Are Underlined in Red in Hubspot

The most common cause of a red underline is that the value does not meet existing validation rules. Typical issues include:

• Required field left empty where the property is marked as mandatory
• Value outside an allowed numeric range
• Text field that is too short or too long for set limits
• Wrong format for emails, URLs, numbers, or dates
• Value not in the allowed list for dropdown, multiple checkboxes, or radio select fields

In Hubspot, each property can have its own configuration on the property edit screen. That is where you will review and adjust those rules if you need to change how validation works.

Step-by-Step: How to Fix a Red Underlined Value in Hubspot

Follow these general steps to correct a value that is underlined in red:

1. Identify the Property and Record in Hubspot

1. Open the affected record, such as a contact, company, deal, or ticket.
2. Locate the specific property that shows a red underline.
3. Hover over or click into the field to check for any error message or hint that appears.

This first step confirms exactly which property and object type you are dealing with in Hubspot.

2. Try Fixing the Value Directly

1. Check if the value might have a simple typo or wrong format.
2. Correct the entry so that it matches the expected pattern, such as a proper email or date.
3. Click outside the field or attempt to save the record again.

If the red underline disappears after you update the value, the problem was purely with the data and not with the property rules themselves.

3. Review Property Settings in Hubspot

If the underline persists or you need different rules, update the property configuration.

1. In your Hubspot account, go to Settings.
2. Navigate to Properties for the relevant object type, such as Contacts or Companies.
3. Search for the property name that had the red underline.
4. Click the property to open its configuration panel.

Here you can see the existing field type, allowed options, and any validation conditions that drive the red underline behavior.

4. Adjust Validation Rules for the Property

Within the property settings, review and modify the parameters that control validation. Depending on the field type in Hubspot, you may see options like:

• Required field: whether the property must have a value
• Minimum or maximum length for text values
• Minimum or maximum values for numerical fields
• Dropdown or multiple checkbox options: the predefined list of allowed values
• Format rules for emails, URLs, or phone numbers

Edit these options so they align with how you actually use the property in your process. Then save your changes in Hubspot.

5. Re-enter or Correct the Value

1. Return to the original record after you update the property rules.
2. Clear the red underlined value if necessary.
3. Enter a new value that now matches the updated validation rules.
4. Save the record again and confirm that the red underline is gone.

This ensures that the property value and the new configuration are fully in sync.

Best Practices for Preventing Red Underlines in Hubspot

To reduce ongoing issues and keep your team productive, follow these practices when setting up and maintaining properties in Hubspot.

Define Clear Data Standards

• Document which properties are required for each object.
• Standardize formats for key fields such as phone numbers and dates.
• Limit free-text fields when a dropdown or set of options will work better.

Clear standards reduce the chance of data being entered incorrectly and triggering red underlines in Hubspot.

Use Validation Rules Thoughtfully

• Only mark fields as required if they are truly essential to your process.
• Avoid overly strict rules that block normal variations in real-world data.
• Group related properties into sections so users understand their context.

The goal is to guide users into entering good data, not to frustrate them with unnecessary error messages.

Train Your Team on Property Behavior in Hubspot

• Explain what a red underline means and how to correct the value.
• Show where to find property settings if they have the right permissions.
• Encourage users to report recurring validation problems so admins can adjust rules.

When everyone understands how the CRM works, you spend less time troubleshooting and more time using Hubspot to drive revenue.
