Hey Deandra,
Thanks!
I wanted to use segments, because you can trigger of a segment change, and my segments are made up of a smart lists (but i dont think you can trigger by joins smart list) They also give you a good view of where your leads are - People can be in many smart lists, but only one segment of a segmenation.
Also i can say if in Lead Status segment "known" AND Segment PST send at 8am pst or something, and Known and EST send at 5am pst.
But overall i am just a little nervous to use the engagement engine was didn't like createing too much trigger logic advanced logic in the
