Using VDV to send email certainly does not violate any terms of service. Was this a permanent disabling, or a temporary? It's hard to find details on google's limits, though they certainly do exist. For example:https://support.google.com/mail/bin/answer.py?hl=en&answer=22839&topic=1669057&ctx=topic specifies that there is a 500 person per message limit, and a limit on bounced messages. It is easy to extrapolate that they may have a "messages in a day" limit as well, though I am unable to find this. If you were generating an enormous number of emails and this was a temporary disabling it is possible you found this limit? If it was a permanent disabling, or you have a low number of emails per day there is likely some other issue at play.
