I tried to skim the official Marketing Cloud doc but I didn't find a clear answer.
Is it possible to enforce an "exactly once" delivery for a triggered send?
The final goal would be to enforce that only one email is ever sent to a given email address for a specific triggered send executed via the REST API.
I've find the possible usage of an Exclusion Script (i.e. https://salesforce.stackexchange.com/a/184793/57712) but I'm actually not sure if it is a viable and proper way to handle my desiderata.
Thanks in advance.
