How to avoid banning a domain during mass mailing (10000)?

Question

Mail server

I don’t even know what technical indicators to indicate here ... I apologize for this ....
We have the task of implementing a one-time mailing to more than 10,000 addresses, what is the best way to implement this project with the least likelihood of blacklisting?
SPF and PTR records are naturally prescribed, but I don’t understand how to avoid this.
mdaemon 14.5

Answer 1

Domains are not included in spam, IP addresses of sending servers are included.

Answer 2

As required by law, obtain the prior express consent of all recipients so that there are no spam complaints from them.

Answer 3

neosun, as Aleksey Lazutin wrote above... there is always a human factor, but at least I try to deal with it. We have 1.2k mail accounts on the domain , the only way out of this situation is to create an additional domain to send commercial offers. Maybe someone has already solved such problems, well, at least limited to 1000-5000 thousand recipients?
Thank you for your help.
