On Sunday January 10th, 2016 between the hours of 9AM-2PM EST we will be performing a system upgrade to unveil a major upgrade to our marketing features in our Control Panel. During this maintenance window the Control Panel will be unavailable. Email delivery via SMTP or HTTP will not be affected. Customers using the existing marketing features in the Control Panel (such as the Newsletter or Autoresponder features) should prepare for several changes as a result of the upgrade.
