It all depends on how well your mail server is set up (there are heaps of ways how to make sure your messages don't get dumped if you are legitimate business) and "reputation" of your servers.
If you run shonky business like KVS does than you cannot have all the required settings to have/gain good "reputation". Obfuscating your real location (is it Canada, USA or Bahamas or whatever country it is), misusing other business services etc, will not work.
I guess Chase doesn't know how to setup a mail server then. BTW I was an email admin for a large government agency and I can assure you that the large providers (MS/Google) would block things (not let them through as Spam) and had nothing to do with the incoming IP "reputation score" (static Class B owned by a large State Government agency). Although trying to get ahold of someone at MS was a royal PITA.
Now we've migrated to O365 where all mail (there is no delineation between "internal" and "external" with O365 Gx tenants) gets treated the same. We've had repeated instances where "internal email" (ie, I send an email to my colleague right across from me) gets treated/marked as Spam.
