Kazi,
I think Email Ninja had a name change recently and is now Genesys Cloud Email Wizard (https://appfoundry.genesys.com/filter/genesyscloud/listing/8e458a3b-bac0-4280-8964-661a3b00b118). If you scroll to the bottom of that listing you'll find additional details and information on how to get in touch with that team to notify them about what you've experienced. You can also use the Contact Us button on the listing as well.
