Remove email address requited attribute in Eloqua-CX Sales integration "deleted contacts" import
The CX Sales integration app includes email address as a required attribute on the import mapping.
Depending on where the contact is deleted from in Sales, the email may also be deleted and the email will appear null in the import. This causes the import to fail.
Ideally, email address could be removed as a required field so we can choose our own other identifiers to match on (such as PartyNumber from Sales Cloud).
