Probably it cannot send email. You can either be sure you can send email through your server and email client working correctly. If not you can try plugins that sends email via SMTP.
You can try https://wordpress.org/plugins/easy-wp-smtp/ this plugin for example. You can open an email account enter smtp details on plugins page. After that you can test that you can send email it should work fine.
Use another contact plugin and check after submit its working or not.
