What is Greylytics?

Greylytics automatically suppresses bad leads from your advertising campaigns. When a contact in your CRM is marked as unqualified — wrong number, unreachable, duplicate, or disqualified — Greylytics adds them to a custom suppression audience in Meta Ads so they stop seeing your ads.

The suppression loop

Here's how it works end to end:

Key concepts

Space — A Space is your workspace in Greylytics. It holds your integrations (Meta Ads, CRM), your lead list, and your settings. Most users have one Space per business or brand. Agency accounts can create multiple Spaces, one per client.

Lead — A lead is a contact that Greylytics has received from your CRM via webhook. Every lead has a sync status that tells you whether they've been added to your Meta Ads suppression audience.

Sync — When Greylytics sends a lead to Meta Ads, that's called a sync. A lead can have a status of Synced, Pending, or Failed. See Understanding lead sync status for what each means.

Custom Audience — The Meta Ads Custom Audience that Greylytics creates and manages on your behalf. It's used as an exclusion on your ad campaigns or ad sets.

What Greylytics does not do

• It does not stop bad leads from entering your CRM — that's your intake process.
• It does not modify your campaigns or ad creative.
• It does not manage your ad spend or bidding.
