I also should have mentioned we use shared IPs so there is no issue
with volume from our servers, however volume from the domain is
definitely spikey. They only send every 2-3 months when they promote

I think you should try and send at least ~100 mails every day to keep
an IP warm. Otherwise you're a ghost...
So now you have to send spam to avoid being thought to be a spammer ?
Microsoft is the same way. It's too common now that you need a continual
and reasonable volume of email from an IP to keep a high reputation.
It's difficult to publicly point to the result in the places that matter
because they're all closed and internal, but it's very noticeable and MS
will tell you it's true if you talk to the right people. This is why I
cut our sending pool down to a /24 from a /22 a while back, spreading
out the volume too thin caused increased spam folder delivery
(determined by testing and volume of user complaints).
