I agree with @smgdarien The slow search on a large order database (155k orders) has made it frustratingly slow for the customer to search orders with the default "All" filter....

What do you mean by subscription expiration date? Your contacts (Subscribers) have join dates but their expiration to your list doesn't automatically expire. They must manually click the unsubscribe link....

I'll ask GetResponse about it. We may have to wait for version 3 of the API, which is currently only in beta: http://apidocs.getresponse.com/en/v3/resources/customfields#customfields.update

Great! So using the PHP Wrapper might look something like this, then: $multivalues = array( 'name_of_your_multivalue_custom' => 'value1', 'name_of_your_multivalue_custom' => 'value2', 'name_of_your_multivalue_custom' => 'value3' ); $setCustoms = $api->setContactCustoms($contactID, $multivalues);
