I struggle to find a way to notify a backend application when an email broadcast is triggered. Is there a way for a REST hook to trigger when a broadcast is send out? Or is there any automation that allows assigning tags to the people that are part of this email broadcast? I know that i can subscribe to tag events via the REST hooks so that would be a suitable workaround.
There is no hook action that will trigger on sending an email broadcast.
This is one of the reasons I don’t prefer broadcasts (lack of controls).
If you use campaign builder to send emails then you can trigger it with tag applications AND tag when it’s sent, meaning you can then use that sent tag to trigger the webhook.
