Customer Impact

What This Means For You

Email tracking pixels operate without recipient consent or awareness. GDPR Article 5(1)(a) requires transparency; invisible tracking violates this. Email fingerprinting enables cross-channel attribution (email → web) without user knowledge.
Recommended Actions

What To Do About It

Role-specific actions based on observed behavior

If You Use Emailchaser

  • →Audit email tracking pixel deployment
  • →Review privacy policy: is email tracking disclosed?
  • →Confirm CAN-SPAM/GDPR compliance for commercial email

If You're Evaluating Emailchaser

  • →Ask: what data does email tracking pixel collect?
  • →Test recipient experience: any disclosure of tracking?
  • →Verify email preference center includes tracking opt-out

Negotiation Leverage

  • →C06 fingerprinting in email tracking pixels creates cross-channel attribution. Is this disclosed to recipients?
  • →C09 consent bypass: email recipients cannot consent to invisible tracking. How do you address GDPR transparency requirements?
  • →Email tracking enables sales surveillance. Does this require disclosure in commercial email?
