Hi @BFocus - I don't think you can as the quarantine list is managed as a global list for all delivery types. I'm also not sure what the use case would be for managing separate quarantine lists. The quarantine list is to prevent you sending emails / SMS to known bad addresses. This is to protect your IP reputation or prevent you sending an SMS to a number that doesn't respond. Do you have a specific reason for a campaign wanting to not use a global quarantine list?
