Leads to mailing list

We have several “status” for our Leads - e.g. “waiting”

I would like, that when a leads gets update with a status - the lead is added to a maillingliste/targelist acc. to that status

How to do that?

I can do a work flow where "if lead has this status " but there seems to be now way, to add it to a specific target list -

anyone with an advice?
