SnS customers never re-evaluate. When eligibility drops, their next order simply doesn't arrive — and Amazon won't tell you. SentryKit fires the instant eligibility changes so you recover before the subscription pipeline empties.
Subscribe & Save is recurring revenue that runs on autopilot — until it doesn't. SentryKit monitors both directions — so you know the instant eligibility drops (and subscribers stop receiving their orders) and the moment it's restored so you can confirm the pipeline is live again.
SentryKit delivers the ASIN, the direction of change, and the timestamp — so you know immediately whether to investigate a loss or confirm a restoration, without manually checking the SnS programme dashboard.
When SentryKit fires an SnS Eligibility Lost alert, you have a narrow window to restore access before subscribers miss an order cycle. These steps cover the most common causes — pricing, account health, and Seller Support escalation.
Recurring revenue is the highest-LTV, lowest-effort revenue on Amazon. SnS eligibility is the gate that keeps it flowing. SentryKit watches that gate so you don't have to.
Manual checks require logging into Seller Central, navigating to the SnS programme dashboard, and reviewing each ASIN individually — a process most sellers do weekly at best. A lot can drain silently in a week.
