In the form of Laravel Project, mail doesn't recieve from user but thank you mail goes to the user. How can I fix this issue?

To troubleshoot the issue where users are not receiving emails from your Laravel project but thank-you emails are being sent, follow these steps:

Check your email configuration: Ensure that your email configuration is set up correctly in the .env file. Make sure that the MAIL_MAILER, MAIL_HOST, MAIL_PORT, MAIL_USERNAME, and MAIL_PASSWORD are correctly configured.

For example:
```
MAIL_MAILER=smtp
MAIL_HOST=mail.example.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=your_email_password
```
Verify that your email server accepts the connection: You can test your email server connection by sending a test email using the Laravel Artisan command:
```
php artisan mail:test
```
If the test email is sent and received successfully, then your email configuration is working fine. If not, you may need to contact your email server administrator for assistance.
Check your email logs: Laravel logs all email-related events in the laravel.log file located in the storage/logs directory. You can check this file to see if there are any errors related to sending emails.
Check your spam folder: Sometimes, emails may end up in the spam folder instead of the inbox. Ask the user to check their spam folder for the missing email.
Use a third-party email service: If you are still experiencing issues with sending emails from your own email server, consider using a third-party email service like SendGrid, Mailgun, or Amazon SES. These services provide reliable email delivery and offer features like email tracking, bounce handling, and spam filtering.
Check your Laravel mailer implementation: Ensure that you are using the correct Laravel mailer method to send emails. For example, to send an email using the Mail facade, use the following code:
```
use Illuminate\Support\Facades\Mail;

// ...

Mail::to('[email protected]')->send(new WelcomeEmail());
```
Check your Laravel queues: If you are using Laravel queues to send emails, ensure that the queues are running correctly. You can check the status of your queues using the following command:
```
php artisan queue:status
```
If you see any queued emails, try running the queues manually using the following command:
```
php artisan queue:work
```

By following these steps, you should be able to identify and fix the issue with users not receiving emails from your Laravel project.
