Merkle is a leading data-driven customer experience management firm that focuses on helping brands enhance their customer interactions to thrive in an increasingly competitive market. Merkle is part of dentsu, and this notice offers no self-service opt-out form — you must email the Data Protection Officer (Americas.DPO@dentsu.com for US/Canada, DPO@dentsu.com globally) or write/call the Americas Privacy Office at (877) 570-5939. Note this notice covers dentsu's own marketing/website data, not Merkle's US data products or client advertising activity; the page links separately to 'go here' for Merkle US data processing requests and to product-specific privacy notices, so a second request may be needed for the data-broker databases. Identity verification is required and no specific response deadline is stated (except 20 days for Mexico).
