If for some reason you are not getting emails from your website (contact form or any other form) then it means the mail function of WordPress is not working properly.
This problem can be caused by several reasons, some hosting companies restrict/disable the mail function for security reasons.
So, the standard way to troubleshoot the email related issue is to install Check Email plugin and send an email to your email address.
If you receive the email then please install and setup WP Mail SMTP Plugin or Postman SMTP Mailer/Email Log Plugin but if it failed then kindly contact you hosting provider and ask them to enable/activate the mail function.
