Salesforce: Campaign Member Deletion

Contact or Lead Deletion

When a Contact or Lead used in a Campaign Member is deleted, all Campaign Members for that lead or contact will also be deleted.

Undeleting the Contact or Lead from the Recycle Bin will restore all Campaign Members for the Contact or Lead, including the Status. However, the Last Modified Date and By of the Campaign Member record will be updated with the timestamp of when the Contact or Lead is undeleted, along with the name of the user who performed the undeletion. The Campaign Member ID will be restored to the original Campaign Member ID.

CampaignMember Deletion

When a Campaign Member record is deleted, it is not sent to the Recycle Bin, so it cannot be restored. Vote for this idea.

Bonus: In the CampaignMember object, there are LeadId, ContactId, and LeadOrContactId fields. For a Lead in Campaign Member, when the Lead converted to a Contact:

• The LeadOrContactId will be updated from LeadId to ContactId
• The LeadId will not be changed
• The ContactId will be populated with the Contact ID
