Bind params create error while to upload the data in phpMyAdmin [duplicate]

I have created an HTML form for uploading the email through input[type="text"] in phpMyAdmin. I have also created a button for adding more input fields for those users who have more than one email ID. By default it shows one input field but when we have to upload more than one email ID and click add email one remove button is also generated for removing that field. For this functionality, I have used JavaScript. When we finish to adding the emails then we have to submit the data. This will redirect to another page i.e. submit_data.php for handling the backend queries. Now in this, I have created a for loop for multiple input data, two more variables I have also added for the member name and date as I have those rows in my table.

My database name is tui_test
The table name is member_email
I have the following rows in my table-
sno, member_name, member_email, date_upload

I error I have seeing after submit the form is-

Warning: mysqli_stmt::bind_param(): Number of elements in type definition string doesn’t match number of bind variables in D:XAMPPhtdocsachievementtestingsubmit_data.php on line 30

Following are the submit_data.php page for handling the backend queries-

<?php
    if ($_SERVER['REQUEST_METHOD']=='POST') {
        // Database connection settings
        $servername = "localhost";
        $username = "root";
        $password = "";
        $database = "tui_test";

        // Create connection
        $conn = new mysqli($servername, $username, $password, $database);

        // Check connection
        if ($conn->connect_error) {
            die("Connection failed: " . $conn->connect_error);
        }

        // Email start
        // Get the email data
        $emails = $_POST['email'];
        $upload_name = 'name';
        date_default_timezone_set('Asia/Kolkata');
        $date = date('Y-m-d H:i:s');

        // Prepare SQL statement to insert data into table "member_email"
        $sqlEmail = "INSERT INTO member_email (member_name, member_email, date_upload) VALUES (?, ?, ?)";
        $stmt1 = $conn->prepare($sqlEmail);

        // Insert each email and date into the table
        for ($i = 0; $i < count($emails); $i++) {
            $stmt1->bind_param("ss", $upload_name, $emails[$i], $date);
            $stmt1->execute();
        }

        // Close the statement and connection
        $stmt1->close();
        // Email end
    }
?>
