Regain lost domain reputation for email by unmarking from spam/replying.

Due to too many cold emails being sent form my domain, my emails now end up in spam on the recipients' end. It was bound to happen eventually. Domain is a year old and has been properly warmed up when beginning. If you can restore the reputation of the emails, that would be what I am looking for. No signups to newspapers. Maybe you have access to many different emails and you can unmark me from spam and keep on replying to me. I will trial with one email address first but I have 7 more so if you do a good job I can award you the next 7 emails
