How WasteNot Optimizes Your Campaigns

WasteNot reduces wasted ad spend by making sure your prospecting campaigns only reach genuinely new customers.

The problem

Advertising platforms like Google Ads and Facebook Ads are designed to maximize conversions. But they cannot tell the difference between a new customer and someone who has already bought from you. This means your "acquisition" campaigns are often just re-targeting existing customers — and you are paying full price for conversions that would have happened anyway.

How WasteNot works

WasteNot sits between your customer data and your advertising platforms:

1. Syncs your customer data from platforms like Shopify, Stripe, and Klaviyo
2. Builds exclusion audiences based on purchase history and engagement
3. Pushes those audiences to your ad platforms as suppression lists
4. Keeps everything in sync so new customers are automatically excluded from future prospecting

What this means for your campaigns

• Prospecting campaigns only reach people who have never bought from you
• Retargeting campaigns can be precisely targeted to lapsed or at-risk customers
• Budget efficiency improves because every dollar goes toward genuine growth

Measuring the impact

After enabling WasteNot, monitor your nCAC to see the impact. Most brands see a meaningful reduction in acquisition costs within the first few weeks as wasted spend is eliminated.
