Why didn't MD's email cancelling match sent via Practiscore reach anyone?

Match director sent out email using Practiscore cancelling match due to rain. But nobody got email and showed up anyway. Which was a good thing as the rain stopped and we went ahead with the outdoor match.

Doug,
Your club seems to be having enough issues lately why don’t you have your match director contact us directly and we can help them.
Have them contact me directly at this email.

Regards,

I will pass along your direct offer to help. Thanks in the past for your patience and answering my questions.
