Digital delivery only
ClaudeStack sells digital skills and learning materials. No physical item is shipped, and no physical shipping fee applies. The product description and checkout identify the digital materials included in your purchase.
How delivery works
After your payment is successfully verified, we send an order email with your product access or download instructions to the email address captured at checkout. Customer login is not required for email based delivery. Course access instructions, where a course is included, are provided with the order.
When to expect your email
Delivery is initiated after payment confirmation. Payment verification, email filtering, or service interruptions can delay receipt. Check your spam, junk, and promotions folders and confirm you used the correct email address.
If your delivery has not arrived within 24 hours of confirmed payment, contact contact@claudestack.xyz with your purchase email and order reference so we can investigate.
Download links and repeat access
Your delivery email contains the access instructions for the product you bought. Follow any download conditions disclosed with your order. If a file link expires or fails, contact support to restore access after purchase verification. Do not share personal download links or redistribute the files.
Incorrect email or failed payment
If you entered the wrong email address, send your order reference and proof of purchase to support. We may request verification before changing delivery details. Failed or unverified payments do not trigger product delivery.
