Is there a free plan, or will I need to pay from day one?
Amp Back in Stock offers a free plan that includes 10 SMS/email/push notifications per month, unlimited sign-ups, multi-language support, and analytics. Paid plans start at $19/month (Lite), $29/month (Startup), and $49/month (Small Business), each with a 14-day free trial and no obligation to continue. SMS notifications on paid plans are charged at an additional $0.015 per sent notification.
Will the 'Notify Me' button work with my existing Shopify theme?
According to the app listing, the Notify Me button works with most Shopify themes and can be customized to match your brand, device type, and language. The app's landing page states you can install and start sending alerts in minutes, matching your Shopify theme with customizable signup forms, pop-ups, and buttons. No developer is required for standard setup.
Does it integrate with Klaviyo, Mailchimp, or other marketing tools I already use?
Yes — Amp Back in Stock integrates with Klaviyo, Mailchimp, Shopify Flow, Zapier, and Upsell by AMP, among others. These integrations are available on paid plans (Lite and above), allowing you to sync subscriber demand data with your existing marketing stack for cohesive workflows.
What notification channels does it support — is it just email, or also SMS and push?
The app supports three notification channels: email, SMS, and web push notifications. Customers can sign up to be notified via any of these channels when an out-of-stock item is restocked. On paid plans, you can also send emails from your own domain for a more branded experience.
Can I use this for pre-orders, or is it only for back-in-stock alerts?
The app handles both use cases. You can add preorder buttons to sell new products before inventory arrives, accepting full or partial payments. Preorder functionality (with 0% revenue share) is available on all paid plans, with the number of monthly preorders scaling from 100 on the Lite plan to unlimited on the Small Business plan.
What do other merchants say about the support team and overall reliability?
With 816 reviews and a 4.9-star rating, the app is broadly well-regarded — 92% of ratings are 5 stars. Merchants frequently praise the support team as responsive and efficient, with individual agents (e.g., Leslie, Jall, James H.) cited by name for fast resolutions. A small number of negative reviews mention occasional display issues and pricing concerns, so experience can vary.
Does it work for international or multi-language stores?
Yes — multi-language support is included on all plans, including the free tier. The app supports customizable 'Notify Me' and preorder buttons that can be configured per language, making it suitable for stores selling to international audiences. The app is used by merchants across the US, UK, Australia, Japan, and many other countries.
