Notifications not working aside from new tickets

it's not working. Any ideas? they get no notification.

my config:

{
  "Closed Sign": "[#262626][[#red]CLOSED[/#]][/#]",
  "Notify About Closing": true,
  "Notify About New Tickets": true,
  "Notify About Replies": true,
  "Notify About Wipes": true,
  "Open Sign": "[#262626][[#C4FF00]OPEN[/#]][/#]",
  "Slack Channel": "general",
  "Title": "[#262626][[#C4FF00]Tickets[/#]][/#]",
  "Use Email API": false,
  "Use Push API": false,
  "Use Slack": false
}
seems none of the notification are working except new.
