Key Features – Restrict Product Purchase by Email

WooCommerce Compatibility:
Designed for WooCommerce; integrates seamlessly into your WordPress admin dashboard.
Per-Product Restrictions:
Upload or manually enter a list of allowed email addresses for each individual product.
Multiple Restrictions Supported:
Easily manage separate rules for multiple products—each product can have its own email list and custom message.
CSV Support:
Accepts .csv file uploads containing one email per line for quick bulk importing.
Manual Entry:
Option to paste email addresses directly into a text area, one per line.
Custom Error Messages:
Define a custom message shown to users whose email isn’t on the list for a given product. Error Messages can be updated at any time, making it easy to adjust wording for clarity, promotions, or product changes.
Product ID-Based Logic:
Restriction management is tied to product IDs for reliable identification and backend control.
Current Restrictions Overview:
View all restricted products in one place, along with the associated email list and custom message.
Editable Inline Email Lists:

Scrollable Email List Field:
To keep the admin UI clean and easy to navigate, long email lists appear in a scrollable text area.
Security Measures:
Uses WordPress nonces to secure form actions and prevent unauthorized changes.
Variations Supported:
Works with simple and variable products (by checking variation IDs if needed).
No JavaScript Required:
Fully functional without JavaScript—ideal for performance-conscious environments or minimal plugin stacks.
Block-based Functionality:
Enforces email restrictions at checkout, regardless of whether you're using the shortcode or the WooCommerce block-based checkout.
