Continuous monitoring
What Is the SellerMagnet Alert System?
The SellerMagnet Alert System is a continuous monitoring engine built into the Analytics Dashboard. It continuously scans your Amazon Seller Central account via the SP-API and generates prompt notifications when changes occur that can affect your revenue, rankings or brand integrity.
Instead of logging into Seller Central multiple times a day, you receive targeted, actionable alerts via in-app notifications, email or webhook, so you can respond in minutes instead of days.

Every Minute Without Alerts Costs You Money
Every minute without monitoring costs you money. Amazon moves fast and problems compound before you notice them.
A Hijacker Appears on Your ASIN
An unauthorized seller undercuts your price by 12%. You lose the Buy Box in minutes.
Without Alerts: You discover it 3 days later. By then, you’ve lost €1,200+ in revenue and your organic rank has dropped.
Your Best-Seller Goes Out of Stock
FBA inventory hits zero on a Friday evening. Restock lead time: 10 days.
Without Alerts: You notice on Monday. 3 days of lost sales, plus 2-4 weeks to recover organic ranking and Buy Box share.
A 1-Star Review Tanks Your Rating
A critical review drops your product from 4.5 to 4.1 stars overnight.
Without Alerts: CVR drops 18% before you even see it. A fast, empathetic response could have turned it around within hours.
* Figures are realistic examples based on aggregated seller data collected in 2025. Actual impact varies by product category, sales volume and marketplace.
The SellerMagnet Solution: continuous alerts give you the signal before the damage becomes irreversible. Connect once, set your rules, and let the system watch 24/7.

Trusted by Amazon Sellers Worldwide
"Caught a hijacker on our best-selling ASIN within the same hour it appeared. Without the alert, we would have lost the Buy Box for days. That single event saved us over €2,400 in lost revenue."
"We manage 8 accounts across all supported marketplaces. Before SellerMagnet, one stockout cost us 3 weeks of rank recovery. Now we get low-stock alerts 48 hours in advance and haven’t had a surprise OOS in 6 months."
"The review alerts alone are worth it. We responded to a critical 1-star review within 30 minutes, resolved the issue and got the review updated to 4 stars. That ASIN’s conversion bounced back the same week."
