Upon checking your form's notification configuration, I found that submission emails are being delivered to your email address "firstname.lastname@example.org".
Please be noted that changing your account email address will not change the email address which is used to receive submission emails. To send submission emails to different email address you need to change the "Recipient E-mail" of your email alert.
Here is a guide which should help you: https://www.jotform.com/help/41-Finding-out-E-mail-Address-used-for-submission-notifications
