Description
WooCommerce Email Blacklist Plugin allows store owners to automatically block and reject orders from specific email addresses during checkout and payment processing.
This plugin helps protect your store from fraud, spam orders, abuse, and repeat offenders by detecting restricted billing or payer email addresses and rejecting the order immediately after payment confirmation.
When a restricted email is detected, the order is automatically marked as rejected, an audit note is added for administrators, and an optional notification email is sent to the customer explaining the rejection.
The plugin integrates seamlessly with WooCommerce and runs silently in the background without affecting legitimate customers.

Frequently Asked Questions
1. How does this plugin work?
This plugin checks the billing email (and payer email when available) after an order is placed. If the email matches one in the blacklist, the order is automatically marked as rejected and a notification email can be sent.
2. Where do I add restricted email addresses?
Restricted emails can be added under WooCommerce > Settings > Products > Email Restrictions & Refunds in the “Restricted email addresses” field.
3. Can I block entire domains?
Yes — entering a domain like @example.com will block any email address from that domain.
4. Will customers still be charged?
Customers are charged normally at checkout. If the email is restricted, the order is rejected afterward. You can disable the email notification or customize how you handle rejected orders on your store.
5. Is the rejection email customizable?
Yes. The plugin sends a standard rejection email, but you can modify the email text using WordPress filters or template overrides if needed.
6. Does this affect other WooCommerce functionality?
No. The plugin only intervenes when a restricted email is detected. Regular orders from allowed emails proceed normally.
7. Can I see why an order was rejected?
Yes. The plugin adds an admin order note indicating that the order was rejected due to a restricted email.
8. Can this plugin block guest checkouts?
Yes. Any checkout that uses a restricted email (guest or registered user) will be blocked and rejected.
9. Does this store additional personal data?
No. It uses standard WooCommerce order data and does not store extra personal information.
10. Can I disable the rejection email?
Yes. There is a setting to enable or disable the rejection email sent to customers.
