I apologize for the experience you were having in your account last night. Maintenance to Constant Contact was scheduled for last night from 11pm-1:30am ET. This maintenance caused some customers to see errors when managing your contacts and emails to not be sent during this time frame. Notifications of this can be seen prior to a scheduled maintenance in your account, in the Community, and on our Status Page as well.
