When you land on a page that just says 404 Not Found, the natural question is whether the link was malicious. In the case of p01i.t.eloqua.com, the evidence points to a tracking pixel that has been removed or expired. The subdomain belongs to Eloqua, a marketing automation platform owned by Oracle. Legitimate marketing emails often include such tracking links to measure open rates, but when a campaign ends, the links stop working.
For a tracking endpoint, security is fine: the certificate is valid and the connection is encrypted. There are no blacklists or threat warnings. The lack of a privacy policy or contact information on this specific subdomain isn't a red flag, because these services typically rely on the parent company's disclosures. That said, because the link leads nowhere, there's nothing to interact with or buy. You won't be asked for payment or personal data here.
If you're worried about whether p01i.t.eloqua.com is a scam, the short answer is no. It's a broken link from a legitimate marketing service. Your focus should be on the original email itself: if the rest of the message looks suspicious, treat it accordingly, but this specific domain isn't the danger.
