Well, yeah.  People can only receive your transmissions if they're
listening.  That kinda goes without saying.

Logically,
therefore, they may send a message via a mode of communication that is
so simple and obvious that we will eventually spot it even without an
active SETI program.

And if you can't conjure up magic from light-years away, what then? 
Logically, you should then broadcast constantly to all even remotely
promising stars nearby, just in case one even starts listening for a
moment.
