I'm getting a ton of email bounces, which I know is not rare, and I'm not sure if it is the 'reply to' email or the 'send from' email that is designating the return address. Any input?
No, it's neither the Reply-To nor the From header that designates the recipient of bounces (DSNs). Bounces go to the envelope sender, which is an address @*.mktomail.com by default; if you've added branded sender(s) to your account, the sender will be @ your domain instead.
