number@vtext.com (SMS), number@mypixmessages.com (MMS) no longer work

Is there a workaround to getting vtext or mypixmessages to work with xfinity? I can not send an email to either and receive it as a text message on my phone. I don't know when it quit working but it is a very valuable feature for me. Is there an app that can convert an email to a text? Is there a way of doing it through forwarding to xfinity mail? What are the options to get around this service being removed from xfinity? I really need it.

Thank you for any helpful ideas.
