您指的是新用户注册网站后发送的电子邮件吗？

如果是这样的话，它是一个可插入的功能，这意味着您可以根据需要超越它。

将此代码放入主题函数中。php。

if( ! function_exists(\'wp_new_user_notification\') ) {
    function wp_new_user_notification($user_id, $plaintext_pass) {
        $user = new WP_User($user_id);
        $user_login = stripslashes($user->user_login);
        $greetings = $user_login;
        if ($user->display_name != \'\') {
            $greetings = $user->display_name; 
        }
        $user_email = stripslashes($user->user_email);
        $email_subject = sprintf(__(\'Welcome to %1$s %2$s!\', \'cell-email\'), get_bloginfo(\'name\'), $greetings);

        $message = \'Your welcome message here\';

        wp_mail($user_email, $email_subject, $message);

    }
}
