## Overview

[AtData](https://www.atdata.com/) is an email intelligence platform that provides email validation, enrichment, and identity matching services. Persona’s integration with AtData enables teams to enrich user data by matching email addresses to postal identities—or vice versa—directly within onboarding, verification, and investigation workflows.

This integration is especially useful for teams that want to improve contact data quality, recover missing emails, or validate identity information using trusted third-party data sources.

## Benefits

**Email enrichment:** Append email addresses to users based on name and postal address data collected during onboarding.

**Identity matching:** Match email addresses to postal identities to improve confidence in user data.

**Improved data quality:** Enhance user profiles with verified and enriched contact information.

**Operational efficiency:** Automate enrichment workflows without requiring manual lookup or third-party tools.

## Integration Features

Persona’s AtData integration enables real-time identity matching and email enrichment within workflows. Key capabilities include:

**Email Append:** Match email addresses to postal contact information using name and address inputs.

**Flexible Input Options:** Support for raw emails as well as hashed formats (SHA-1, MD5, SHA-256) for privacy-preserving workflows.

**Structured Enrichment Data:** Retrieve matched email addresses and associated identity signals for use in downstream workflow logic.
