+<!--TODO DOCS-586 Issue description-->
+
+There may be different reasons for this issue to happen:
+
+-   **The commit email address isn't associated with the account of a Codacy Cloud user**
+
+    Make sure the user [updates the email addresses associated with their Codacy account](../../account/emails.md#updating) to include the missing commit email address.
+
+-   **Git isn't configured with the correct email address**
+
+    Make sure the user [sets the Git email address](../../account/emails.md#git-config) correctly.
