PurposeRecords the date of the most recent Pardot engagement activity on a Lead. Used by the Cold Lead logic (C-02) to determine whether a Lead has been inactive for 365 or more days. Without this field, recency-based cold lead qualification cannot function. Field definition| Object | Lead |

How the Flow works- Trigger: a Pardot engagement activity is created or synced to the Lead record
- Condition: activity type is one of the approved types above
- Action: stamp Last_Interaction_Date__c with today's date
- Overwrite rule: always overwrite with the most recent date — no set-once logic.
This field is write-once per event, not cumulative. It stores only the date of the most recent qualifying activity — not a count or history of all interactions. Full interaction history remains in the Pardot Engagement History related list on the Lead. |
Dependency — Cold Lead logic (C-02)The Cold Lead flow reads Last_Interaction_Date__c to determine inactivity. If this field is blank, the Lead is treated as having never interacted and will qualify as cold (assuming no other exclusion applies). If this field is populated but older than 365 days, the Lead also qualifies as cold. If the Flow that populates Last_Interaction_Date__c is inactive or misconfigured, cold lead qualification will be unreliable. CRM Admin must monitor Flow error logs and ensure the Flow is active whenever a Clay campaign is running. |

Logic Exclusion rules — any one of these disqualifies the lead - HasOptedOutOfEmail = TRUE → exclude
- clay_overall_hard_bounce__c = TRUE → exclude
- Lead has one or more related Contact records → exclude
Positive rules — lead must meet at least one - Status = 'Unqualified' → always cold
- Any other status + Last_Interaction_Date__c is NULL or older than 365 days → cold
