Hi @JMF21. There are lots of reasons for this. The customer could have changed their email address and deleted the one you have on file. Their email box could be full. Their email service could be suspended for some reason. Their email service could be having technical issues. And the list goes one.
My recommendation would be to look at their customer record and see if you have a phone number on file you can use to contact them.
Good luck.
