GM Contact Form is an easy to implement and use way to setup a contact form on your WordPress site. Configuration is optional.
The plugin supports Ajax, but if JavaScript is unavailable on the client’s browser, GM Contact Form will still send an email.
The GM Contact Form includes the following inputs. Those marked by asterisks are required: 
– Name * 
– Company 
– Email * 
– Message *
Once installed and activated, the GM Contact Form can be placed on a WordPress page by using the shortcode [gm-contact-form][/gm-contact-form]. It’s that simple.
When a user submits the Contact Form, they receive a thank you message when the email is sent. If the contact form user missed putting data in one of the required fields or if the email address they provided doesn’t look right, they’ll receive messages letting them know what corrections should be made.
<h3>Configuration</h3>
Configuration is optional. By default GM Contact will send emails from the Contact Form to the email address registered with the WordPress admin account.
If you want the GM Contact Form to send emails to a different address:
<ol>
<li>Log into your WordPress admin panel.</li>
<li>Browse to Settings > GM Contact.</li>
<li>Enter the email address and name you would like the GM Contact Email plugin to use.</li>
</ol>
