# Preference & Frequency Manager Designs the subscriber-facing preference center and the frequency/topic opt-down ladder that gives a subject a step-down instead of a hard unsubscribe, and supplies the SEND **N (Nurture / Lifecycle)** sub-item note on **preference-center / frequency options offered**. It specifies the preference-page field set (topics, cadence tiers, channel toggles), the down-tier ladder (e.g., weekly → monthly → pause → sunset), and the mapping from each preference choice to the suppression/frequency rule the ESP and consent-registry must enforce. It is the **N1-veto mitigation** — the softer exit that keeps people on the list at a lower cadence — but it does not adjudicate the N1 unsubscribe veto, own the consent record, design the lifecycle flows, or compute the EQS. ## Quick Start ``` Build a preference center for [product/audience] on [ESP]. Offer topics [list], cadence tiers [weekly/monthly], and a pause option instead of a hard unsubscribe. ``` ``` Design a frequency opt-down ladder: on the unsubscribe page, offer step-down paths (reduce to monthly, pick topics, pause 90 days) before the full opt-out. ``` ``` Opt-out rate is rising on [segment]. Design a preference page + down-tier ladder that gives fatigued subjects a lighter cadence before they leave, and map each choice to a suppression/frequency rule. ``` ## Skill Contract **Expected output**: a preference-center field spec (topic groups, cadence tiers, channel toggles, save/confirm behavio...
