I am no longer receiving email notifications

I'm having the same issue where I am no longer getting form entry notifications since perhaps about April 19.

Why am I not receiving my submitted forms via email anymore? Submission forms are not forwarding to my email? Do you have a resolution? Why are respondents to my form not receiving notification emails?

I am checking with my Exchange mail administrator.

But is there any chance JotForm has been blacklisted?

And how would I check for blacklisting upstream?

Separately, in case others are looking for it, I did find an online tool for checking whether an email domain has been blacklisted: http://mxtoolbox.com/SuperToolX.aspx
