+Dear {{ user.first_name }},
+
+Your need to re-confirm that you still use your account on the BEAT Platform.
+This check is done on a yearly basis.
+
+This can be done by going to your profile and making a revalidation request by
+clicking on the corresponding button.
+
+If you haven't done this by this expiration date: {{ expiration_date }}, your account
+will be blocked and you will then need to go trough an unblock account
+procedure to re-activate it.
