Can Rules do this with email?

I am using Rules to send out reminder emails to users who have not logged in after X days, the idea being that we want them to come back and do stuff on our site.

These messages might get a bit monotonous, so it would be great if I could create a pool of possible messages to be sent with different copy or calls to action to re-engage users so they are not always getting the same messages.

Can Rules send a random message, like Views can display a random node of a type, when reacting on a certain event?
