// Your email address for subscribers and contact form
$config['emailaddress'] = 'kurac@live.com';

// Should a csv file be generated?
$config['savecsv'] = false;
// the name of the CSV file
$config['csvfile'] = 'emails.csv';

// Use MailChimp? (http://www.mailchimp.com/)
$config['mailchimp'] = false;

// API Key - get won at http://admin.mailchimp.com/account/api-key-popup
$config['mc_apikey'] = 'YOUR MAILCHIMP APIKEY';

// Login to MC account, go to List, then settings, and look for the List ID entry
$config['mc_listId'] = 'YOUR MAILCHIMP LIST ID';

// Use Campaignmonitor? (http://www.campaignmonitor.com/)
$config['campaignmonitor'] = false;

// API Key - see http://www.campaignmonitor.com/api/
$config['cm_apikey'] = 'YOUR CAMPAIGNMONITOR APIKEY';

// Login to CM account, select a client from the list, go to Lists & Subscribers, then select or create a list, and go to 'change name/type'
$config['cm_listId'] = 'YOUR CAMPAIGNMONITOR LIST ID';

// do not edit beneath this point

// make some constants for easy access
