Advertisers using Enhanced Conversions plus Customer Match were auto-enrolled in conversion-based lists

Menachem Ani shared the notification on X that Google would automatically turn on conversion-based customer lists for eligible advertisers, with data processing starting August 18 unless they opt out.

Reported by Search Engine Land and Search Engine Roundtable on June 19. Google had described automatic classification of conversion-based lists two days earlier, but the auto-enrollment mechanics were surfaced via advertiser notifications.
