Email error when emailing from within Teamzy?

Hi All!

I have just had 3 rejects when trying to email from within Teamzy.  The same emails look to have gone through OK when I send from my email account directly. Am I doing something wrong?

Here is the error message:

Delivery to the following recipient failed permanently:

    bradleys@tds.net

Technical details of permanent failure: 
Message rejected.  See https://support.google.com/mail/answer/69585 for more information.
