We have various trigger sends definitions setup for transactional notifications. The TSD have now gone live and there has couple of errors under the same error code:
"messageErrorCode":180008,"messageErrorStatus":"Unable to queue Triggered Send request. There are no valid subscribers."
However I have checked all the attributes, their types and validations seems to be correct.The API requests doesn't even get through the Triggered data extensions or Triggered Send Definitions. The type of email addresses in the API requests are:
email@example.com firstname.lastname@example.org email@example.com
I am guessing the List Detective in sfmc is filtering out these types of email addresses and it is a concern for business because these are transactional requests and cannot be ignored.
Has anyone been able to bypass/turn off the List Detective or is there a way to pass these requests in API to TSD?
