Multiple sending IPs not assigned to specific brands
Our enterprise portal has two sending IP addresses (not including our transactional IP addresses).
Hubspot should allow enterprise users with multiple brands to assign a specific sending IP to a specific brand. One brand's IP sender score rating shouldn't affect another brand's ability to avoid spam filters due to high volume sending.
Multiple sending IPs not assigned to specific brands
Using your illustration, here is our current setup:
Dedicated IP Address #1 === brandA.com + brandB.com [up to max sending volume]
Dedicated IP Address #2 === brandA.com + brandB.com [after max sending volume of IP Address #1 is reached]
Dedicated IP Address #3 === brandA.com + brandB.com (transactional)
So, in the current setup, if brandA.com has a large send that may have low open rates, then brandB.com is affected because using the same IP means sharing the same sender score rating. Thusly brandB.com is put into the spam folder because of a bad send from brandA.com.

Using your illustration, here is our ideal setup:
Dedicated IP Address #1 === brandA.com
Dedicated IP Address #2 === brandB.com
Dedicated IP Address #3 === brandA.com + brandB.com (transactional)
Ideally, we would like assign specific brands to specific IPs or even add additional IPs per brand to prevent brandA.com from affecting brandB.com.

Yes, we have contacted both the HubSpot Email Deliverabilty team and our Designated Tech Support. It has been reported that HubSpot does not have the ability to assign IPs per brand within one enterprise portal supporting multiple brands. The solution may be more complicated that currently illustrated here since we have seven+ brands not only two withing one portal.
