Unable to receive contact form submissions

If you're not able to receive the email that user submit via the contact form,  you will have to do is install Postman SMTP plugin, configure it with the Wizard and you are good to go!
  1. Install and activate Postman SMTP through the 'Plugins' menu in WordPress.
  2. In the WordPress 'Settings' menu select 'Postman SMTP'.
  3. Choose 'Start the Wizard' and follow the instructions.

Contact your webhost for the SMTP details for your website.

After following the instructions it's important to go to Postman SMTP->Show All Settings->Message and check the "Prevent plugins and themes from changing this" for both the Email address and name.

Thanks to Jason Hendriks for the awesome plugin! :)
