Exclusions that keep acquisition budgets focused.

Connect your customer data, define who should be suppressed, and keep every Meta and Google campaign focused on net-new buyers.

Three steps. Ten minutes. Zero code.

01
Connect your data
Link Shopify, Klaviyo, Stripe, HubSpot, your warehouse — any customer signal you want suppressing on. API keys, no engineering ticket.
02
Set your rules
Use a point-and-click rule builder to define exactly who gets excluded — purchases, signup recency, lifetime value, whatever fits the campaign.
03
Protect every campaign
WasteNot pushes fresh exclusions to Meta and Google daily — always within the platform 28-day refresh window. Set it once, forget the spreadsheet.

Designed for the people who actually run paid acquisition — built to live alongside the rest of your stack.

350+ data source connections

Shopify, Stripe, Klaviyo, HubSpot, BigQuery, Snowflake, Postgres — and a long tail of niche tools your stack runs on.

Codeless rule builder

Compose definitions like "bought in last 90 days" or "high-LTV repeat buyer" in seconds. Preview audience size before you publish.

Cross-platform sync

Daily auto-apply across Meta and Google Ads. Audiences are always under the platform 28-day refresh threshold, so they never lapse.

Built for ad ops

Audit logs, granular permissions, environment-aware rules. Your ops team stays in control as the company scales.

Real-time refresh

When a customer converts, they're suppressed within hours — not weeks. No more paying to retarget yesterday's buyer.

Match-rate transparency

See exactly how much of your audience is hitting each platform — no more guessing why CRM uploads only reach half your list.

Walk through your data, your campaigns, and the exact rules your team would launch with. No slideware.
