I see several issues about that in the issue queue, so I would suggest looking there. There is a parameter (at least in D7) to tell Token to suppress empty strings, so there should be a setting for it.

Subject: [support] question about rules module

Hi, I have a rule that sends posts out, but when there is no body of a post
I see

[node:body]

Is there a way to see if [node:body] is empty to use another email template
to send out or a way to stop empty tokens from being shown an the email?

Thanks.
