Configuring assign action type as email action for self service

Hello.

I’d like to replace smart mail with email action for managing email templates and so on. I noticed that it works fine for actions starting from assyst Portal. However, I could not replicate such behavior for events logged from self service portal by end users. My guess is that when contact users are logging events, they do not select an email template. Nonetheless, if there’s something like a system parameter for such use case, I guess we’d be able to substitute Smart Mail with Email Actions.

Am I right or is there something else I should know?
