Hi! I was implementing some new emails and couldn't figure out an issue - some mails were not showing up on activity feed. Turns out I was sending an invalid receiver email (id instead of email). The weird part is that sending the trigger worked fine, it was acknowledged and even a transactionId was returned, but on the platform these triggers are already filtered out. This made it difficult to debug as the entire flow seemed to work. Is there any way to have this as part of input validation so a trigger with a bad email throws an error? Or have them show up on activity feed with the 'invalid configuration' like what happens for example if a 'sendAt' is in the past? Extra info: I am using the PHP SDK
