Groups - Authenticating SMS

Hello,
I am creating a group "goalies".  I have successfully added some external e-mail accounts.  I am trying to add and e-mail to SMS account, eg. 6071234567@txt. att.net.  My phone receives the authentication email but it is truncated and I am unable to click on the authentication link because that part of the message doesn't show.  Here is an example of what I receive -

Is there anything I can do to add an SMS email account to a ZOHO Group?

Thank you.
