+{{ $total_updates }} package updates are available for your server {{ $name }}.
+
+## Summary
+
+- Operating System: {{ ucfirst($osId) }}
+- Package Manager: {{ $package_manager }}
+- Total Updates: {{ $total_updates }}
+
+## Available Updates
+
+@if ($total_updates > 0)
+@foreach ($updates as $update)
+
+Package: {{ $update['package'] }} ({{ $update['architecture'] }}), from version {{ $update['current_version'] }} to {{ $update['new_version'] }} at repository {{ $update['repository'] ?? 'Unknown' }}
+@endforeach
+
+## Security Considerations
+
+Some of these updates may include important security patches. We recommend reviewing and applying these updates promptly.
+
+### Critical packages that may require container/server/service restarts:
+@php
+$criticalPackages = collect($updates)->filter(function ($update) {
+                return str_contains(strtolower($update['package']), 'docker') ||
+                    str_contains(strtolower($update['package']), 'kernel') ||
+                    str_contains(strtolower($update['package']), 'openssh') ||
+                    str_contains(strtolower($update['package']), 'ssl');
+            });
+@endphp
+
+@if ($criticalPackages->count() > 0)
+@foreach ($criticalPackages as $package)
+- {{ $package['package'] }}: {{ $package['current_version'] }} → {{ $package['new_version'] }}
+@endforeach
+@else
+No critical packages requiring container restarts detected.
+@endif
+
+## Next Steps
+
+1. Review the available updates
+2. Plan maintenance window if critical packages are involved
+3. Apply updates through the Coolify dashboard
+4. Monitor services after updates are applied
+@else
+Your server is up to date! No packages require updating at this time.
+@endif
