I am not receiving form submissions via email

Forms (Rain Makeup Form) are being submitted by I am not receiving them via email.  The email address is correct (atkinsonrenee@comcast.net) but for some reason I haven't received any submissions since 1/18 even though there are several.  

Your email is not in our servers' bounce list, so notifications should arrive just fine. May I advise you to look for the missing notifications in your SPAM folder?  

Meanwhile, I shall be conducting more investigation to see if something else is amiss. I will let you know my results thereafter.

Update:

I tested a clone of your form multiple times, and I received the notifications on my personal Gmail account just fine. I have also checked your account's email notification history, and found out that your email was added to our bounce list multiple times.

When your email is added to our bounce list, it means that your mail provider blocks the emails from our servers. 

If this happens again, we recommend that you contact your mail provider and ask them to whitelist notifications coming from us.

What does "ask them to whitelist" emails coming from us mean? What information will they need about where the emails are coming from?

You can ask them to whitelist noreply@jotform.com. Here are the full list https://www.jotform.com/help/145-Whitelisting-JotMails-IP-Addresses.

Take note that our mail server uses dynamic IP address, meaning the IP may change over time. With that said, whitelisting all the IPs from the guide above does not ensure you of a bounce free email. 

If your email still goes in the bounce list, we recommend you to use your SMTP server to send emails. Guide: http://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form
