Last Phone Change

Track when each contact's phone number changes with automatic timestamp logging

Overview

Clean Dial's Last Phone Change Tracking automatically monitors and records when phone numbers are updated on your HubSpot contact records. This feature creates a complete audit trail of phone number modifications, helping you identify when contact data may need validation and ensuring your outreach efforts target the most current information.
Last Phone Change Property on Contact

How It Works

When phone numbers are updated on contact records, Clean Dial automatically:
    Detects changes to the Phone Number property on Contact records
    Captures the exact timestamp when the change occurred
    Saves this timestamp to a custom property called Last Phone Change
This happens seamlessly in the background - no additional workflow setup required.

Setting Up the Custom Property

To view phone change timestamps on your contact records:
    Navigate to CRM > Contacts
    Select any contact record
    Go to Key Information section
    Click Actions > Customize Properties
    Search for "Last Phone Change" under the Clean Dial section
    Add the property to display on contact records
