Hi @armancse,
We have checked the email feature, which works fine in our testing environment and with other users.
If you have recently set up your site, there is a high chance that your WordPress installation is not set up correctly for sending the email. To test this, you can install this very simple plugin called Check Email: https://www.ads-software.com/plugins/check-email/
Once the plugin has been installed and activated.
Go to Tools->Check Mail.
Under Send Test Email, enter your site’s email address where you would like to receive a test email.
Then click on the Send Test Email button.
If your WordPress site SMTP is correctly set up, you will receive a test email in the email address you entered. If this fails, you must contact your host and ask them to fix the email configuration.
Alternatively, you can also use the SMTP plugin to set up SMTP on your site easily. Check this documentation to learn how to set up SMTP using the Easy WP SMTP plugin: https://docs.everestforms.net/docs/how-to-setup-smtp-using-easy-wp-smtp/
Regards!
