How to Block Disposable Email Addresses in Laravel (Prevent Fake Registrations)

If your Laravel application allows user registration, there's a good chance you've encountered disposable email addresses.

These temporary email services allow users to create email accounts that expire after a short period of time. While they can be useful for privacy-conscious users, they are frequently used to:

• Create fake accounts


• Abuse free trials


• Bypass verification systems


• Exploit referral programs


• Generate spam registrations

For SaaS products, communities, e-commerce platforms, and membership websites, disposable emails can become a serious problem.

To solve this issue, I built TempMailBlocker, an open-source Laravel package that helps developers detect and block temporary email addresses during validation.
