To manage spending effectively without the Existing Customer Budget Cap, use these workarounds:
1. Create Separate Campaigns – Run one campaign for new customers and another for existing customers instead of relying on automatic budget caps.
2. Manual Audience Segmentation – Use Custom Audiences to target existing customers and Lookalike Audiences for new customer acquisition.
3. Use Advantage Campaign Budget (ACB) – Optimize budget distribution across multiple ad sets by setting minimum spend caps for new customers.
4. Set Exclusions in Ad Sets – Exclude past purchasers or loyalty program members from new customer-focused ad sets.
These adjustments help maintain budget efficiency and control over customer targeting despite Meta’s changes.
