Personalized pacing

Definition

Personalized pacing is the practice of determining per-user optimal messaging frequency and temporal distribution, rather than applying a global rate threshold across all users. Each user receives a pacing plan tailored to their engagement patterns, channel preferences, and fatigue tolerance.

Key implementation patterns: - Uniform random pacing: frequency target → per-opportunity send probability → weighted coin flip. Produces organically randomized patterns matching the target rate. - Non-uniform pacing: day-of-week patterns, user-activity-conditioned sends, launch-aligned bursts — richer temporal profiles when UX requires structure. - Discretized action space: express the pacing decision as a choice among ~O(100) combinations of channel-frequency pairs, keeping optimization tractable.

Personalized pacing contrasts with threshold-based frequency control, where a single relevance-score cutoff implicitly determines aggregate send rate but offers no per-user differentiation.
