+<p>
+  There's been a fatal error with your batch export {{ name }} at {{ time }}. Due to the nature of the error, it cannot be retried automatically and requires manual intervention.
+
+  We recommend reviewing the batch export logs for error details:
+</p>
+
+<div class="mb mt text-center">
+  <a href="https://us.posthog.com/project/{{ team }}/batch_exports/{{ id }}"
+     target="_blank"><b>Go to the batch export</b></a>
+</div>
+
+<p>
+  After reviewing the logs, and addressing any errors in them, you can retry the batch export run manually. If the batch export continues to fail we will disable it.
