I have a tableView of id, name, mail, phone and select.
I wanna get all selected row of my tableView and add selected mail to my email list in my model class.

Is the FilteredList Solution appropriate for you?
It is hard to say. It is one potential approach.
As trashgod notes in the comments, the best approach for your application may depend on your overall UI and application architecture.
For example, rather than using the filtered list, you could have a Save button or some other commit point, where it checks a dirty flag such as the modelChanged flag in trashgod's solution (or even do away with the listener/modelChanged concept completely). Then just iterate over the original list extracting any items which are selected at that point in time, and reflect those values back in your model (e.g. commit to the database). Such would be a kind of MVVM approach, where the observable list for selection is just involved as the view-model (VM) and the separate list of committed mailing information is the model (M).
Even if you did use the separate save point approach outlined above, perhaps the addition of the filtered list could still ease the conversion task for you, as all you would need to do is look at all items in the filtered list.
Also, the filtered list could be used in other functions of the app, such as the mailing list view displayed in this solution.
