There are lots of reasons for testing that your WordPress site is sending emails properly. Maybe you’ve just added or updated an email-related plugin or for some other reason you want to ensure that WordPress is able to send emails and they are being delivered.
WP Sent Mail has a “Test Email” page that makes this quite simple. Navigate to WP Admin > WP Sent Mail > Test Email, enter an email address, and click the “Send Test Email” button.
When the form submits WP Sent Mail calls the wp_mail function and sends a simple test email to the address you entered.
