Hi, I'm using a third party app to assigned lead owners based on a round robin. I works fine but is lacking email notifcation when the queue changes the ownership to the user.

I'm trying to get a WFR that will action this but becuase ownership is changing immediately, I'm struggling. I've tried various WFR including

Owner:User.Profile.Name = "Sales User"
ISCHANGE(OwnerId)

but none of these have an effect.

You can see the lead history on create here, is there anything I can do that doesn't include a timebased workflow?
