Is there a way for the second email ID of the Client/Lead profile to recieve a macro (email send to them) automatically as well?

Is there a way for the second email ID of the Client/Lead profile to recieve a macro (email send to them) automatically as well?

I think that when I send macro email to recent entries and part of these have two emails listed, just the primary email gets the information. I want that second email to be receiving the correspondence as well. And if possible - to add third email field/box. Thank you!
