+
+    <p><strong>1. Using the Dappnode Interface:</strong> For an active Dappnode, simply navigate to <a href="http://my.dappnode/system/notifications">System > Notifications</a> and toggle off <b>Ethical Metrics</b>. This will stop all notifications and halt metric collection from your Dappnode. As long as Ethical Metrics notifications are enabled in the Dappnode UI, your device remains registered in our monitoring system.</p>
 
-  Unregistering from the monitoring system is as easy as uninstalling the Ethical Metrics package. After uninstalling the package, you will no longer receive notifications, and we will no longer collect metrics from your dappnode.
+    <p><strong>2. For Inactive Dappnodes:</strong> If your Dappnode is no longer accessible, locate the <b>unregister link</b> in the welcome email you received upon registration. Keep in mind that using this method won't employ our IP hiding measures, but you can enhance security using tools like a VPN. Please keep in mind that if your DAppNode is still up and running with Ethical Metrics notifications turned on, it'll register again by itself.</p>
+
+    <p><strong>3. Manual Unregistration:</strong> Lost the welcome email? You can also unregister by inputting the following URL into your browser: <code>https://ethical-metrics.dappnode.io/unregister-from-email/?instance=<i>YOUR_INSTANCE</i>.onion%3A9090</code>. Make sure to replace <i>YOUR_INSTANCE</i> with the unique identifier for your Dappnode, excluding ".onion:9090".</p>
