<p>Here are a few examples of how to use the <a title="Package supporting the parsing, manipulating, and generating email messages, including MIME documents." class="reference external" href="email.html#module-email"><tt class="xref docutils literal"><span class="pre">email</span></tt></a> package to read, write,
and send simple email messages, as well as more complex MIME messages.</p>
<p>First, let’s see how to create and send a simple text message:</p>
