eBlast and Blacklisting

We are going to contract a company to manage our marketing via eBlast. I am concern about the possible issues with our domain getting blacklisted. Our marketing department wants to use a subdomain of our domain to do the eblast.

for example our domain is domain.com - they want to use edition.domain.com

My understanding is that the vendor should be using their public IP and will be able to send as edition.domain.com
by spoofing I guess. So that our public IP addresses are not blacklisted.

Any ideas or guidance on how to deal with this?

Domains do not get blacklisted - it is IP addresses that get blacklisted.
If the vendor isn't using one of their own domains for the bounces, you should probably setup a sub domain with its own MX records to handle them. However this is one of those things that you need to follow the vendor's guidance on.

Can they send from the their IP addresses as one of our subdomains for example editorial.mymaindomain.com
if so, how is the setup going to look like?

Usually bulk email from a provider would be something like

from address.example.com@theirdomain.com on behalf of user@example.com

Sending from a sub domain in your domain is unusual, as the hassle involved with setting it up is rarely worth it.

However these are questions the vendor should be answering, it is their network and they can tell you what setup you need to do if anything.
