A common use for a web form is a 'contact us' or 'enquiry form' that is embedded on your website. 

Notification of these being submitted is really important, a web form has the email action capabilities that any other form in Formitize has. 

An easy way to be notified that a form has been submitted is an Email PDF, this video shows how this can be set up and for an email to be sent to your company email upon submission.
