Answer 1

MailChimp API v3.0 is now live! and they've also added a better batch operations feature which lets you make multiple operations in just one call. You can use below code with the help of this php wrapper for MailChimp apiV3 for the batch operations.

    $data1 =array(
            'email_address' => 'testingmail1@gmail.com',
            'status' => 'subscribed',
            'merge_fields' => array('FNAME' => 'Testing', 'LNAME' => 'Mail1'));
    $data2 =
        array(
            'email_address' => 'testingmail2@example.com',
            'status' => 'subscribed',
            'merge_fields' => array('FNAME' => 'Testing', 'LNAME' => 'Mail2'));
    $attributes = array(
        'operations' => array(
            array(
                'path' => 'lists/' . $listID . '/members',
                'method' => 'POST',
                'body' => json_encode($data1)
            ),
            array(
                'path' => 'lists/' . $listID . '/members',
                'method' => 'POST',
                'body' => json_encode($data2)
            ),
        ));

    $response = $MailChimp->post('batches/', $attributes);
