Questions

Before you sign up

What does SentryKit actually watch?

+

50+ signals across nine groups: fees and margin, Buy Box and pricing, account health and policy, listing health and suppression, product content and fields, reviews and feedback, rank and visibility, inventory and fulfilment, and competitors and hijackers. Every group is included on every plan.

Do I need to connect my Amazon account?

+

Yes. SentryKit reads your listings through Amazon's official Selling Partner API, which is what makes the alerts specific to your catalogue. It takes about two minutes during signup and you can disconnect at any time.

How is this different from checking Seller Central?

+

Seller Central shows you what happened once you go looking, and its Business Reports run on a delay. SentryKit tells you when it happens, without you looking.

Where do the alerts arrive?

+

Email, and Slack if you connect a workspace. You choose which signal groups you want, so a large catalogue does not become noise.

Is there a limit on ASINs?

+

No. ASINs, orders and marketplaces are unlimited on every plan. Price moves on one axis only, which is how many storefronts you run.

What happens after the 14 days?

+

Nothing automatic. No card is taken at signup, so the trial cannot roll into a charge. You pick a plan only if you want to carry on, and ASGTG members get 25% off Pro for the first 3 months with code SK_ASGTG_25.
