JooPeter Email to Product Buyers for WooCommerce

JooPeter Email to Product Buyers for WooCommerce is a lightweight and efficient plugin that helps store owners communicate directly with their customers. It adds a convenient meta box to the WooCommerce product edit screen, allowing you to send custom emails specifically to users who have purchased that product.

Key Features:

• Targeted Emails: Automatically fetches customers who have purchased the current product.
• Dynamic Order Status Chips: Toggle order status filters (Processing, On Hold, Completed) with real-time customer counts.
• Chunked AJAX Batch Sending: Dispatches emails in batches (e.g. 10 at a time) to prevent server timeout errors and spikes.
• Control Center (JooPeter Email Panel): Centralized admin dashboard under Tools menu to manage logs and settings.
• Email Logs History: Tracks total, successful, and failed email dispatches with statistical cards.
• Send Countdown Delay: Prevent accidental sends with a cancelable 10-second countdown before dispatches.
• Bulk Retry: Bulk retry sending all failed emails with a single click.
• Selective Clearing: Clear only successful email logs, keeping failed logs for troubleshooting.
• Sender Tracking: Captures and logs the display name of the WordPress user who sent each email.
• Log Retention Settings: Automatically prune expired logs after 7, 14, 30, 90, or 180 days, or keep them forever.
• Access Permissions: Configure which user roles are permitted to see the product editor meta box and send emails.
• Duplicate Protection: Ensures each customer receives the email only once, even if they bought the product multiple times.
• Performance: Uses object caching to minimize database load on large stores.

1. Upload the plugin files to the /wp-content/plugins/joopeter-email-to-product-buyers-for-woocommerce directory, or install the plugin through the WordPress plugins screen directly.
2. Activate the plugin through the ‘Plugins’ screen in WordPress.
3. Configure role permissions under Tools > JooPeter Email Panel > Permissions & Settings.
4. Navigate to any WooCommerce Product edit page to find the “Email Customers Who Bought This Product” meta box in the sidebar.

Does this save a log of sent emails?

Yes, the plugin saves a history of sent emails inside the JooPeter Email Panel (accessible under the Tools menu). It logs the date/time, recipient, product, subject, sender’s name, and delivery status (success/failed).

Can I retry failed emails?

Yes! The Control Center provides a Retry Failed Emails bulk action button that will resend all emails marked as failed.

Can I control who can send emails?

Yes, under the Permissions & Settings tab in the Control Center, administrators can select which user roles have access to the product editor email composer meta box.

How long are logs saved?

You can customize log retention settings under the Permissions & Settings tab to automatically prune logs older than 7, 14, 30, 90, or 180 days. You can also disable pruning by selecting “Keep Forever”.

Can I cancel a send after clicking the button?

Yes, the plugin features a cancelable 10-second countdown. If you click send and realize there is an issue, you can click the red “Cancel Send” button before the timer hits zero to safely abort the send.
