Google has started notifying advertisers that it will automatically enable Conversion based Customer Lists for eligible accounts. According to the email, the rollout begins on June 17, 2026, with data processing starting on August 18, 2026.
The change applies to advertisers already using Enhanced Conversions and Customer Match but who have not activated this feature yet.
No action is required, although advertisers can opt out before August 18, 2026.
Once enabled, these audiences can be attached to campaigns for additional first party targeting opportunities.
This email was shared by Arpan Banerjee.
