+Notification Options
+--------------------
+
+Lemur currently has very basic support for notifications. Notifications are sent to the certificate creator, owner and
+security team as specified by the `SECURITY_TEAM_EMAIL` configuration parameter.
+
+The template for all of these notifications lives under lemur/template/event.html and can be easily modified to fit your
+needs.
+
+Certificates marked as in-active will **not** be notified of upcoming expiration. This enables a user to essentially
+silence the expiration. If a certificate is active and is expiring the above will be notified at 30, 15, 5, 2 days
+respectively.
+
+Lemur supports sending certification expiration notifications through SES and SMTP.
+
+
+.. data:: LEMUR_EMAIL_SENDER
+    :noindex:
+
+            Specifies which service will be delivering notification emails. Valid values are `SMTP` or `SES`
+
+.. note::
+    If using STMP as your provider you will need to define additional configuration options as specified by Flask-Mail.
+    See: `Flask-Mail <https://pythonhosted.org/Flask-Mail>`_
+
+    If you are using SES the email specified by the `LEMUR_MAIL` configuration will need to be verified by AWS before
+    you can send any mail. See: `Verifying Email Address in Amazon SES <http://docs.aws.amazon.com/ses/latest/DeveloperGuide/verify-email-addresses.html>`_
