I use it for Amazon to send out emails to our customers about product. After setting everything up, I just left it there. Their token expired for 3 months but they didn't send out any alerts or warnings that they weren't able to send out emails through Amazon and yet kept charging the monthly billed amount. So much for an "automated" email service. When I contacted them about it, they said it was not their fault and refused to credit for the months inactive when they rendered no service to us. Do not know how to do business.
