Kelso: Back in Stock Alerts
Restock alerts that never miss.
When inventory comes back, every subscriber gets their email. A webhook detects the restock. A reconciliation poll runs behind it, so a dropped webhook never becomes a missed sale. Every send is logged from queued to delivered.
No revenue share. No overage fees. Flat pricing.

Reliability
Restock detection runs on two paths. The inventory webhook fires first. A scheduled reconciliation poll checks behind it. Shopify does not guarantee webhook delivery. We plan for that.
Flat pricing
One flat monthly fee for a send allowance. No revenue share. No per-unit fees. No overage charges. Over your limit, sends hold until you upgrade or the month resets. Nothing gets dropped.
Human support
Email support@kelsohq.com and a person replies in hours, not days. No bots, no ticket purgatory. Our support promise is on the support page.
