Where Notify Me! is stronger
- Social proof. A very large, very positive review base is meaningful evidence the app works well for many stores. Restock Rocket is new; we have to earn that.
- Multi-channel alerts. Email, SMS, and web push cover customers who don't check email quickly. If your audience responds to SMS or push, that reach is a genuine advantage — Restock Rocket is email-only in V1.
- A free tier and a large suite. Essential Apps runs several widely used Shopify apps with a sizeable team; if you already use their other apps, staying in one ecosystem is convenient.
Where Restock Rocket is stronger
- Measured, published alert speed. The pipeline is webhook-driven with an immediate send queue targeting under 60 seconds from restock, and the dashboard shows your store's real p50/p95 latency and % under 60 s — a verifiable number, not a marketing adjective. The mechanism is documented in how alerts work.
- The Demand Report. Beyond alerting, your waitlist becomes purchasing data: sold-out products ranked by waiting customers, with history and CSV export (Pro) — built for the restock decision itself.
- Strict revenue attribution. A sale counts as recovered only when an order containing the product follows an alert click within 72 hours. You know exactly what the number means.
- Simple, predictable pricing. Three plans, unlimited alerts at $49/month, and quota-paused (never lost) alerts if you hit a limit. No channel add-ons to price in.
Our honest verdict: if you want alerts on more channels than email — SMS and push — or you prefer the reassurance of a massive review base, Notify Me! Back in Stock is a very good app and the safer social choice. If your priority is the fastest email alert with the receipts on your own dashboard, plus demand data that improves your next purchase order, Restock Rocket is built precisely for that. Both start free, so trying costs nothing.
