:::caution[Coming soon]
The official Syvel app is not yet available on the Shopify App Store. This page describes the planned integration and its features.

In the meantime, you can validate emails via the [REST API](/docs/api/check) from a Shopify Function, a server-side webhook, or a custom storefront.

## What the integration will do

The Syvel Shopify app will let you block disposable and temporary email addresses at two critical touchpoints — without any code required.

## Customer registration

Block accounts created with throwaway email providers before they are stored in your customer database. The check runs at registration time and shows an error if the address is detected as disposable.

## Checkout

Validate the email address entered at checkout. If a disposable address is detected, the customer is asked to use a real address before completing their order — preventing order fraud and unreachable delivery notifications.

## Configuration

After installing the app, connect your Syvel API key and choose a sensitivity threshold:

- **Standard** — blocks well-known disposable providers (yopmail, mailinator, etc.)
- **Strict** — also blocks lesser-known providers and high-risk free domains
- **Custom** — fine-tune based on your own risk tolerance
