-Red Mail Logging Handlers
-=========================
+Email Logging with Red Mail
+===========================
 
 Red Mail also has logging handlers which
-work with the *logging* library from Python's
-standard library. You may also use the `SMTPHandler <https://docs.python.org/3/library/logging.handlers.html#logging.handlers.SMTPHandler>`_ 
-from logging library but Red Mail provides more 
-customizable alternatives. Red Mail also has a 
-handler that is capable of sending multiple 
-records at once.
+extends the :stdlib:`logging library's <logging.html>`
+:stdlib:`logging handlers <logging.handlers.html>`. 
+The logging library already has 
+:stdlib:`SMTPHandler <logging.handlers.html#smtphandler>`
+but the features are somewhat restricted. It does only 
+send a logging message formatted as plain text. 
+
+Red Mail's email handlers are capable of formatting the 
+log records in arbitrary ways using Jinja, creating 
+visually more pleasing HTML emails and sending multiple 
+log records via email at once.
+
+If you would like to send one email per log record,
+:ref:`ext-emailhandler` is what you need. In case you 
+would like to reduce the amount of emails and send 
+multiple log records at once, use :ref:`ext-multiemailhandler`.
