Should tracking pixels be disclosed?

Whether tracking pixels should be disclosed is debated. GDPR's transparency requirements suggest informing recipients about data collection including tracking. Privacy focused best practices favor disclosure.

Practical disclosure might appear in privacy policies linked from emails or subscription signup processes. Some senders explicitly note tracking in footers. The trend toward transparency suggests proactive disclosure builds trust.

Apple's Mail Privacy Protection and similar developments reduce tracking effectiveness regardless of disclosure. As tracking becomes less reliable, the ethical question of disclosure may become less practically significant while remaining relevant for principle.
