# Overview

The Email Intelligence API lets you submit one or more email addresses and receive a comprehensive risk assessment. Results are delivered via webhook and are always available in the [Dashboard](https://dashboard.verisoul.ai). It is designed for offline, asynchronous use cases where you need deep analysis before making a decision about an email.

## Identity Intelligence

For customers doing account creation, onboarding, or high-value transactions, The Email Intelligence API offers an optional **Identity Intelligence** layer that goes beyond email-level signals.

When enabled, Verisoul performs deeper identity analysis:

* **Online Presence** — discover which platforms an email is registered on (Google, Facebook, LinkedIn, etc.)
* **Name & Phone Verification** — match provided claims (name, phone, country) against identity data linked to the email
* **Connected Identities** — surface names, phone numbers, and countries associated with the email across data sources

## How It Differs from Real-Time Email Scoring

Verisoul's `/session/authenticate` endpoint provides email risk context as part of a real-time session and account. The Email Intelligence API provides richer signals and is purpose-built for standalone email decisions.

|                           | Real-Time (Authenticate) | Email Intelligence API                      |
| ------------------------- | ------------------------ | ------------------------------------------- |
| **Use case**              | Inline session scoring   | Standalone email analysis                   |
| **Delivery**              | Synchronous response     | Asynchronous webhook                        |
| **Identity Intelligence** | Not available            | Optional deep identity analysis             |
| **Claims matching**       | Not available            | Per-email name, phone, country verification |
| **Batch support**         | No                       | Up to 1,000 emails per request              |
