It shows error message when I tried to Test Send a marketing email. The error message shows as below:
There was a problem with the test send. Error: Exception 'InvalidPluginExecutionException' occured: Failed to pre create email test send., CorrelationId: d37caec0-bc18-4bf0-849b-4323bbd74e14
And I have checked that the Marketing Page is in Live status.
Please may I ask if anything I can do. Thank you!
