Hi Florent:
Thanks for you reply.
Yes. If Adobe Campaign support send email by my own JS connector, I can write a connector to send emaill over http.
But the next issue I meet.
(1) If I set the External Account with ["Channel" = "Email"] and ["Delivery mode" = "Bulk delivery"], I cannot set the JS Connector to it.
(2) If I set the External Account with ["Channel" = "Email"] and ["Delivery mode" = "external"], I can set the JS Connector to it, but the JS connector was not execute when I send a email.
Would you like to tell me how to configuration a Email External Account to specify a JS connector.
Best regards.
