Please take a look at this 3rd party module:
They have just released a new version that supports Sitefinity 4.3.
I think this is in our TO-DO list, however I am not sure when this feature would be implemented. As you know there are many upcoming features that wait to be implemented. We will try to fit this implementation into our schedule for the next major release.
I can confirm that this feature is coming in 5.0 next year. We won't be able to add it for 4.4. Not sure if you know, but there won't be 4.5 release. We are going to 5.0 right after 4.4.
Can you please elaborate on "email triggering"? Do you mean e-mail bounce-tracking?
I agree absolutely, and we have already wireframes on how this will work. We'll add it to the product as soon as possible, but I cannot promise when exactly.
