This plugin, like many others, provides a shortcode to add a simple contact form in any page of your site. The difference is that messages are stored on-site, using a custom post type. Instead of sending the whole message by e-mail, just a 
notification is sent in configurable intervals.
The shortcode syntax is the following:
<pre><code>[cpt-contact-form] </code></pre>
Please note that no default styling is provided, so if the form looks crappy, you’ll have to find a way to provide the 
relevant css yourself, by adjusting your child theme’s style.css or otherwise.
When a message is stored, shortcodes are stripped and html attributes are escaped. Although, I’m planning to add a configuration option for that in the future.
The plugin is in (hopefully correct) English, but a Greek translation is provided as well.

CPT Contact Form

A contact form that utilizes a custom post type to host messages on-site instead of directly sending them by e-mail.
