Hi Lap,

Thank you for the quick response!

I tried this thing and it works, but unfortunately it’s not the functionality I want.

The above code will add to MailChimp only the users that have a specific meta_value, however I want to sync all users into MailChimp, but change their status to UNSUBSCRIBED if the specific meta_value is present.

Any idea on how to do that ?

I’ve tried the following code, but it doesn’t work ??

add_filter( 'mailchimp_sync_user_data', function( $data, $user ) {
    $data['STATUS'] = $user->receiveInformation;             
    // receiveInformation has Subscribed/Unsubscribed values

    return $data;
}, 10, 2 );

I am following up on this, as I still couldn’t make it work ??

Lap, could you please have a look at my last comment ?

To reiterate, I want on first sync the plugin to change the Subscribed/Unsubscribed field in MailChimp depending on whether a specific WP user meta is true or false.

Would that be possible to achieve it ?

Many thanks,

Hi Cboom,

The snippet that my colleague shared should actually do just that. It will not only send the users with that meta key to MailChimp but it will actively unsubscribe everyone without that meta key as well.

The final snippet in your case would look something like this:

/**
* Only synchronise users with a meta field named "mailchimp_opted_in" with boolean value true
*/
add_filter( 'mailchimp_sync_should_sync_user', function( $should, $user ) {
   return $should && (bool) $user->receiveInformation;	
}, 10, 2 );
