Criteo retargets consumers via email

In 2016, when data scientist Fred Benenson investigated why he had received an email from Sears asking if he was still interested in a product shortly after he had browsed for it on the Sears website, he discovered that Sears had contracted the French company Criteo to make this type of connection. Although Benenson had never given Sears his email address, Criteo could use the cookie it placed on his machine to match other information held about him in advertising partners' databases and sign him up for the email he received. Benenson found that this end run around the opt-in process is probably legal in the US, he regarded it as contrary to user expectations and ripe for abuse.
