If you do not receive the submitted contact forms, please check the following:
1. Make sure the contact form is setup with a valid email address:
- Edit your Website and from 'Pages in your website' menu, select Webpage which contains the contact form 
- Left-clicking on a contact form field to edit it  and at the Edit tool bar, make sure a valid email address is entered into the 'Send to' field .
(If the entered email address is '[email protected]', make sure you replace it with your e-mail address)
2. Make sure submitted forms are not routed to the Spam folder of your email account:
When a form is submitted, it gets automatically compiled into an automatic email and sent from the routing alias '[email protected]' to the email address your contact form is setup with.
As the email is automatically generated, it's likely that it gets routed to the Spam folder of the email account/address your contact form is setup with.
Therefore, if the automatic emails containing the submitted forms data are not received in your INBOX, please check the SPAM/BULK folder for them.
If it's the case and in order to receive the automatic emails directly in your INBOX, all you need to do is to authorize the alias '[email protected]' at your Spam Filter settings level.
