By default, WordPress uses the PHP mail function to send out email notifications. However, this function doesn't work as expected due to a number of reasons.
Most WordPress hosting companies restrict usage of this function to prevent abuse and spam.
Spam filters on popular email service providers check incoming emails to monitor if they are sent from authentic mail servers. Default WordPress emails fail this check and sometimes may not even make it to the spam folder.
SMTP (Simple Mail Transfer Protocol) is an industry standard for sending emails. Unlike the PHP mail function, SMTP uses proper authentication, which can improve e-mail deliverability.
Gmail provides an SMTP service, which you can use to send emails from your WordPress website. If you only want to send WordPress notification emails to yourself and a few users on your site , the Gmail SMTP server is the best choice.
However, if you plan to use WordPress to send newsletter emails , you should use a popular email service provider, such as Sendinblue or Mailgun.

Log in to your cPanel account and create an email account that matches your Google apps email address. This might seem strange because you're not using your server for emails. This step tricks your server into believing that you're sending the email through the server.
In your cPanel account, go to the MX Records and change the MX routing from automatic to remote. It might be a little tricky to find since each host now has a custom cPanel interface. You need to look for a small link next to MX that says Email Routing: Remote Mail Exchanger.
