--- title: System Health & Advanced Settings description: Monitor your automation engine, troubleshoot common issues, and manage advanced plugin maintenance. --- NotifyBay is built to be a robust, "set and forget" solution. However, for high-volume stores, it’s important to know how to check the "health" of your notification engine and where to go if something isn't working as expected. This guide covers the **Status** and **Advanced** tabs located in your NotifyBay settings. --- ## 1. Monitoring the Background Engine Navigate to **NotifyBay > Status** to see the real-time performance of your automated notification queue. ### The Engine Queue (Jobs) NotifyBay processes emails in small batches to ensure your site remains fast for other shoppers. The **Action Scheduler Queue** card shows exactly how many notifications are in flight. ![Action Scheduler Queue Card](/notifybay/assets/screenshots/status-engine-queue.png) * **Pending:** Your "to-do" list. These are customers waiting for an email in the next scheduled batch. * **In-Progress:** What the engine is working on at this exact second. * **Complete:** A historical count of successfully sent notifications. * **Failed:** Emails that couldn't be sent. This usually points to an issue with your site's email server (SMTP) rather than the plugin itself. ### Lead Health (Diagnostics) This card helps you identify if specific customer data points are getting stuck in the database. ![Lead Health Diagnostic Card](/notifybay/assets/screenshots/status-lead-health-card.png) * **In Processing:** Leads currently being evaluated by the engine. If this number stays high for more than an hour, it may indicate a conflict with another plugin. * **Failed Leads:** These are subscribers that encountered a permanent error (e.g., an invalid email format). You can review and fix these in your [Leads Table](/notifybay/leads/lead-management/). --- ## 2. Troubleshooting Common Merchant Issues ### "My customers aren't receiving emails" If your analytics show notifications are being "Sent" but customers claim they haven't received them, follow these steps: 1. **Check Spam:** Ask the customer to check their junk folder. 2. **Verify Sender Email:** Ensure your "From Email" in **Settings > Email Templates** matches your domain (e.g., `sales@yourstore.com`). 3. **Install an SMTP Plugin:** We strongly recommend using a dedicated SMTP plugin (like WP Mail SMTP) to ensure high deliverability and prevent your emails from being blocked by providers like Gmail or Outlook. ### "The 'Notify Me' button isn't appearing" 1. **Check Stock Status:** Ensure the product is set to **"Out of Stock"** in WooCommerce. 2. **Check Settings:** Verify that the Waitlist feature is enabled in **Settings > General**. 3. **Theme Conflict:** If you are using a custom page builder (like Elementor), you may need to place the button manually using [Shortcodes or Blocks](/notifybay/getting-started/manual-placement/). --- ## 3. Advanced Maintenance The **Advanced** tab contains powerful tools usually reserved for troubleshooting or store migrations. ### Debug Mode (Developer Logging) If you contact our support team, they might ask you to enable **Developer Logging**. ![Debug Mode Toggle](/notifybay/assets/screenshots/status-advanced-debug.png) - **What it does:** Writes a detailed "play-by-play" of the plugin's background actions into your WooCommerce logs. - **Where to find logs:** Navigate to **WooCommerce > Status > Logs** and look for files starting with `notifybay-`. - **Important:** Disable this once your issue is resolved to save server disk space. ### The "Deep Uninstall" Option This setting determines what happens to your data if you delete the NotifyBay plugin. ![Deep Uninstall Setting](/notifybay/assets/screenshots/status-advanced-uninstall.png) - **OFF (Default):** Keeps your data safe. If you delete and later reinstall NotifyBay, your thousands of leads and analytics history will still be there. - **ON:** Wipes the slate clean. This will **permanently erase** all leads, analytics, and settings from your database when the plugin is deleted. > [!WARNING] > Only enable **Deep Uninstall** if you are certain you want to lose all your NotifyBay data forever. We recommend taking a database backup first.
