Yes, you can use a CNAME to help avoid adblockers with Mixpanel. According to the documentation, for hosted subdomains that don't allow cross-subdomain cookies, you can use a CNAME to change from yourdomain.hostapp.com to yourdomain.com as an alternative to disabling cross-subdomain cookies.
This is mentioned specifically in the JavaScript SDK documentation:
However, while a CNAME can help in some cases, Mixpanel generally recommends setting up a proxy server as the more comprehensive solution for dealing with adblockers. The proxy approach is mentioned in multiple documents as the recommended way to reduce data loss from adblockers:
Choosing the Right Method notes that with client-side tracking, "You may lose events for 30-50% of your users. You can resolve this by sending events through a proxy, but it requires a bit more effort."
If you're looking for the easiest option, you might want to consider server-side tracking instead, which is completely immune to adblockers and provides more reliable data collection.
