If your rules in Outlook are not marking the mail as spam then the anti-spam system your email provider is using is doing that. Your email provider will have to contact SpamHaus.org or other to get upwork removed from the blacklist.
As Valerie said look at the header of the email. Upwork uses different servers for difference messages, so some could get marked as spam and others not. And show that header to your email provider.
You can look yourself to see if Upwork is flagged as a spammer. For example with this tool.
And enter the IP address of the sending server (i.e, upwork's server which seems to be mailgun.net), which you can read from the email header like these two lines:
domain of mg.upwork.com designates 22.214.171.124 as permitted sender
Received: from do158-66.mailgun.net (do158-66.mailgun.net [126.96.36.199]) by mx.zohomail.com

Upwork obviously has an issue with these types of email notifications. Either their SPF, DMARC, or DKIM records are incorrect because I have multiple email providers (exchange online and Apple mail) both rejecting these messages.
You might want to reach out to the Customer Service team. Since this problem has not been reported by anyone else in the Forums (this is the Forums), the problem may not be a simple as it seems.

this has been happening to me for a long time. and my email is from my own website. so its not some "outdated" host. its really annoying. upwork is obviously doing something wrong if people are having this issue. seems silly to me that we have to contact our email providers and and try to get upwork unblacklisted in order for their emails to be recieved. and it didnt do this for the first few months. once i realized it, i had missed quite a few notifications. very annoying.
I'm sorry about the issue you're experiencing with receiving email notifications. Our team will reach out to you directly via a support ticket, take a closer look and provide more information.
