The URL https://core.verisk.com/?utm_medium=email&utm_source=outlook&utm_campaign=Email_Signiture&utm_content=LOB-Hub works for me (Chrome, Chrome Incognito, Firefox), the parameters all stay in place for me.
If you open your browser, open the network panel, and then try to load the above, do you see this page get redirected? (301 or 302, etc status code), then the https://core.verisk.com/ url getting a 200 response?
This redirect could be coming from your server? Or possibly a privacy extension on your browser (something that doesn't load in incognito).. if the site redirects, there's not much you can do... identifying what is causing the site to redirect for you at least is the first step to understanding the potential impact. If it's your server doing it (unlikely since it works for me, and it works for you in incognito), then you can talk to your DevOPs team...
You should also be aware that iOS17 will start removing parameters for users in Private Mode, navigating from Messaging or Mail apps... there is also a setting to apply this change to all Browsing...
Apparently FF also has had a query parameter stripping feature since June 2022, but again this is an optional setting that must be manually turned on by users...
