Hello,
this isn’t a viable option, unfortunately. I totally get the difficulties one faces nowadays to succesfully send a newsletter that will (hopefully) hit the subscribers inboxes, however there is no guarantees that even a second email address won’t bounce back incoming newsletters. It’s a complex matter, we know that. What I can suggest to do is to improve every aspect of the so called deliverability, apart from that, bounces can still occur but there’s little we can do at that point.
Thanks,
Michael
