Laravel Mail Not Sending? Eight Fixes That Work

Emails that never arrive from a Laravel app are a very common problem, often despite code that appears correct and no obvious error. The guide says the cause is usually something small and recommends checking the likeliest culprits first, such as the .env settings, stale config cache, and mismatched port and encryption. It also covers queues that never process because no worker is running, and Gmail rejecting normal passwords in favor of App Passwords. Readers are pointed to storage/logs/laravel.log for error details and to a quick tinker test to confirm whether SMTP is working.
