Are you having problems sending operational emails?

[Anonymous]

Is anyone else having issues sending operational emails since the April 19th, 2013 release?

Starting 4/19/13 all of our operational emails sends are resulting in a soft bounce error of "System send failure: Error: email doc is invalid".

Curious if anyone else is running into this issue.

The only operational email bounces that we've had since 4/19 were hard bounces due to an unknown contact.  You should open a case with tech support.

Not aware of any problems here.
