Troubleshooting: Laravel Not Sending Email and Not Giving Errors
Email functionality is a core part of many web applications, and Laravel offers a robust solution for handling emails. However, it can be quite perplexing when your Laravel application isn't sending emails and isn't throwing any errors. This scenario can lead to significant debugging challenges. Here are some steps to help you identify and resolve the problem.
Check Basic Configuration
Environment Configuration
Ensure that your environment variables are correctly set in your .env file. The basic configuration for mail services looks like this:

Inconsistencies or mistakes in the .env file can lead to silent failures. Also, remember to clear the configuration cache if you make changes:

Mail Driver Settings
Ensure that the correct mail driver is set. Laravel supports several mail drivers like SMTP, Mailgun, and Amazon SES. Make sure the driver you're using is properly configured in the config/mail.php file.

Inspect the Logs
Check your laravel.log file located in the storage directory. Even if no errors are prominently displayed in the application, there might be breadcrumbs or warnings logged there.

Debug Mailing Service
Test with a Minimal Setup
Create a minimal test route to send an email. This can help isolate configuration issues from application logic problems. For instance, consider adding the following route in your web.php file:

Visit your-app-domain/test-email to test if the mail is sent.
Verify SMTP Credentials
Incorrect SMTP credentials can cause emails not to be sent without explicitly generating errors. Verify that your SMTP credentials like username, password, host, and port are accurate.
Common Pitfall Areas
Email Queue
If you are using Laravel's queue mechanism to send emails, ensure that the queue worker is running:

Additionally, check if there are exceptions in the failed_jobs table if you are using a database driver for queues.
Error Handling
Sometimes, third-party SMTP services might delay or silently fail email delivery. Consider wrapping your email-sending logic in try-catch blocks and logging the exception to catch subtle errors:

Network Issues
A firewall or network issue might prevent your application from connecting to the SMTP server. Try sending emails using a local SMTP server or another network to rule out connectivity issues.
Advanced Debugging
Mailtrap
Using services like Mailtrap can allow you to monitor the emails sent by your application in a development environment. It helps in identifying issues specific to your production SMTP setup.
PHPUnit Testing
Utilize PHPUnit for testing your mail functionality. Create test cases to ensure that your mail logic is correct, and your emails are dispatched properly.

Conclusion
When Laravel fails to send emails and doesn’t produce any errors, it’s crucial to systematically check your configuration, validate credentials, and inspect logs. Using debugging tools and techniques like minimal setup routes, try-catch blocks, and services like Mailtrap can assist you in pinpointing the issue.
Resolving email sending issues in Laravel, especially without error messages, requires a methodical approach. Following the steps mentioned above can help you identify and fix the problem effectively.
