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.

How we build · 3 commitmentsSPEC SHEET K-100
K-101

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.

K-102

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.
