Magento 2 Disposable Email Validator

Adds ability to block against 90,000+ known disposable/temporary email domains during customer registration.

Description

Disposable email addresses (like tempmail.com, guerrillamail.com, etc.) are commonly used for spam registrations, fake accounts, and abuse. This module validates emails against 90,000+ known disposable email domains and blocks them during customer registration.

Recommended usage: By default, Magento does not require email confirmation during customer registration. Without email confirmation enabled, blocking disposable emails has limited effect — users can still register with any fake but valid-looking email address. I recommend enabling this module alongside Magento's email confirmation feature (Stores → Configuration → Customers → Customer Configuration → Create New Account Options → Require Emails Confirmation).

Features

• Validates against 90,000+ disposable email domains (auto-updated via composer)
• Custom blocklist — add your own domains to block
• Whitelist support — allow specific domains to bypass validation

Installation

composer require max-stan/magento2-disposable-email-validator
bin/magento mod:en MaxStan_DisposableEmailValidator
