Email to Text (vtext.com) Not Working

[PghExpat]

I have had automatic email to text messages sent to my iPhone for many years now with nary an issue.  Last week I stopped receiving all automatic messages to my vtext.com address.  I've tried to send a sample email to text message from my Gmail account to my iPhone and the message is not received.  The root cause appears to be on Verizon's end.

PghExpat, we want to make sure you are able to continue to receive emails to texts. Let's review. Can you please confirm that your mobile device has the latest Software Update? Also, which text message application are you using on your device?
