When you use the FormidablePro plugin (and we use it a lot when developing WordPress websites) to collect data from visitors to your website, you can set a form to send you an email notifying you of the fact that the form was submitted. However, email is simply, to my mind, one of the weakest links on and least reliable aspects of the Internet.
So even if you set up email notification, you will want to check form entries on a regular basis to make sure you don’t miss anything (I also recommend setting up a Twilio text message alert, but that’s for another day).
This tutorial shows you how to check for entries (or submissions) from your Formidable Pro form.
