Introduction

Laravel Disposable Email is a fast, offline email validator designed to detect and block disposable, temporary, and fake email addresses before they enter your Laravel application.

When users register with throwaway inboxes like Mailinator, 10MinuteMail, or Temp-Mail, applications suffer from drained free trial credits, polluted databases, and hard bounces that damage your SMTP domain reputation.

This package eliminates fraudulent registrations using an open-source dataset of 124,220+ verified disposable domains. It runs natively inside your application across Laravel 10, 11, 12, and 13, delivering instant protection with zero third-party API dependencies and zero recurring subscription costs.

What Makes It Unique

• Zero-Latency Offline Validation: Operates entirely within your application. No outbound HTTP calls, no third-party API downtime, and no added latency to signup forms.
• 124,220+ Preloaded Threat Domains: Ships with comprehensive domain coverage to identify and halt burner email services on contact.
• Multi-Layered Verification: Combines local domain blocklists with optional RFC 5322 syntax compliance and live DNS MX record lookups.
• Custom Blacklist & Whitelist Control: Safely whitelist corporate or testing domains while mounting your own custom blacklist files directly from storage.
• Automated List Updates: Keep threat data up to date using native background synchronization with the Laravel console scheduler.
