when comes to email, macro initiator sends an e-mail that the treatment received by the system.
open in $L.new="Open" and null(cpx.impact in $L.new)
E-mail information about the macro takes from callback.contact:
How can I exclude from sending one particular contact?
callback.contact in $L.new ~="username" and (open in $L.new="Open" and null(cpx.impact in $L.new))
It leads to the fact that the macro does not work.
