suppression list
It is often overlooked but valuable for efficiency and compliance: not spending on people you should not contact or do not need to contact.
In practice
Build suppression into every campaign, not as an afterthought. Keep a standing suppression audience (recent buyers, opt-outs, open complaints) and confirm every send references it before the campaign goes live. The audiences you exclude protect both budget and consent.
