Retention Retainers: Why Lifecycle Marketing Reprices Agency Revenue

Lifecycle marketing converts agency revenue from project spikes into compounding retainers because every triggered message, winback flow, and loyalty tier produces measurable revenue that renews itself. The strategic risk is platform lock-in: expertise built on one engagement suite does not transfer cleanly when a client migrates stacks. Agencies that treat lifecycle as a data and measurement discipline rather than a tool skill capture the margin; those that resell a single vendor's interface rent their book of business.
