Matching without a shared ID
Match members on email alone, or on a first and last name paired with a phone number or zip code. These are the same identifiers StackAdapt uses to resolve a person.
StackAdapt
Polytomic connects your data warehouse, databases, and SaaS tools to sync audiences to StackAdapt from your first-party data. Use Polytomic's no-code UI or the Polytomic MCP server to sync audiences to StackAdapt without writing a line of code.
Rate limits respected
Requests that exceed StackAdapt's query budget are detected automatically. Polytomic backs off and retries instead of failing the batch.
Audiences discovered automatically
Every CRM audience already built in StackAdapt appears as a destination automatically. There is no ID to look up by hand.
Example workflows
Push warehouse customer lists into StackAdapt for retargeting
What you can sync

How it works
Connect an API key and point a sync at an audience you already built in StackAdapt. Polytomic discovers every CRM audience in your account automatically.
Each sync only adds members to the audience. There is no update or delete path. Send email, name, phone number, and zip code as plain values. StackAdapt hashes them for matching on its side.
- Existing CRM audiences discovered automatically, with no manual lookup
- Match members by email alone, or name with phone or zip
- Send plaintext values that StackAdapt hashes for matching
- Choose Experian, LiveRamp, or both for identity resolution
- Every sync only adds members, never updates or removes them
- Requests that exceed StackAdapt's query budget retry automatically
How to set up
