SAP Emarsys has four types of block lists.

SAP Emarsys maintains four block list types to manage contact exclusions:

Option D (Complaints):Correct. Notorious complainers—contacts who frequently mark emails as spam or complain—are added to the Complaints block list to prevent further sends and protect sender reputation.

Option A (Internal):Incorrect. Internal block lists are for manual exclusions (e.g., employees), not complainers.

Option B (Robinson):Incorrect. The Robinson list is for contacts who have opted out via a third-party list, not specifically complainers.

Option C (Global Suppression):Incorrect. Global Suppression is a broader list for legal or compliance-based exclusions, not complaint-specific.The SAP Emarsys Help Portal under "Block Lists" identifies the Complaints list for this purpose.References:SAP Emarsys Help Portal - "Block Lists" (https://help.emarsys.com/ ).
