+## Sent Emails
 
 LocalStack keeps track of all sent emails for retrospection.
+The sent messages can be retrieved in following ways:
+- Filesystem: All messages are saved to the state directory (see [filesystem layout]({{< ref "filesystem" >}})).
+    The files are saved as JSON in the `ses/` subdirectory and organised by message ID.
+- API endpoint: LocalStack provides a service endpoint (`/_aws/ses`) which can be used to return in-memory saved messages.
+    A `GET` call returns all messages.
+    Query parameters `id` and `email` can be used to filter by message ID and message source respectively.
+    A `DELETE` call clears all messages from the memory.
+    The query parameter `id` can be used to delete only a specific message.
 
-The sent messages can be retrieved via a service API endpoint (GET `/_aws/ses`) or from the filesystem.
