5. Submit to MailChimp when – select your preferred option for when attendees/registrant should be added to a specific list on MailChimp. The default option to add when a registration is completed with an approved status.

Usage for the Event Espresso 4 MailChimp Integration

Now when you are creating or editing an event, you will have a MailChimp List box. This drop-down menu allows you to specify which MailChimp mailing list to add the attendees too. The list must already exist, so if you want to have each event have a separate list, you will first need to create the lists in MailChimp. Event Espresso 4 will pass the attendee’s first name, last name, and their email address to MailChimp.

Groups

You can also set up the groups within the lists in your MailChimp account. Once groups are set up within a list, you select that list in the Event editor in the MailChimp List integration box. Once a list that has groups is selected a new select box will appear below that will let you select a group.

List merge fields (new feature in Event Espresso 4)

Event Espresso 4 allows you to use custom merge fields within your MailChimp lists and then select which question’s answer should be sent for which merge field. So for example within your MailChimp list you need to collect the company name, so you set this as an extra merge field within your list and set it to required:

The EE4 MailChimp integration will display these merge fields within the MailChimp integration box, and allow you to select which question’s answer should be sent for which field:

function tw_limit_mailchimp_list_call( $params, $mailchimp_controler ) {
    $params['limit'] = 50;
    return $params;

}
add_filter( 'FHEE__EE_MCI_Controller__mci_get_users_lists__list_params', 'tw_limit_mailchimp_list_call', 10, 2 );
