Turn on error report or troubleshooting universal email
I feel like I've asked this in years past, but I can't seem to find an answer in the threads. A client website with a long standing web form has discovered they're not receiving submissions. I've tried alternative receiving addresses and indeed, regardless of junk mail filters we're not getting delivery.
I'm looking for a guide or guidance on how to troubleshoot. Is there error reporting we can turn on on the page? What are some things to troubleshoot?
