How do I mask or anonymize PII data in Marketing Cloud? I don't want to do a full Contact Delete as I want to keep the contact record for tracking and reporting purposes. However, I want all PII like name, email address, phone number, etc. to be masked/anonymized or deleted in all of Marketing Cloud.
I've already looked at Subscriber delete and that anonymizes PII but that just removes them from Email Studio and not all of Marketing Cloud.
I'm looking to do this on a weekly basis so I'm looking for an automated solution if possible.
