First, make sure you have an email notification set up under "Form Settings->Notifications". The system will not automatically send emails when your form is submitted, so you need to set up a Notification in order to receive emails.
If you have Notifications set up and are not receiving them, check your email's spam or junk mail folder. If your email program connects to a webmail account, be sure to log in to the webmail and check that junk mail folder, too.
If you determine that the messages are not in your junk mail folder, please contact Formsite support to help track your messages.
Pro tip: Add email@example.com and firstname.lastname@example.org to your address book to proactively tell your email program that we're not spam.
