@dvankooten. Again, thank you for taking time to answer.
My question is: If the basic plugin (MC4WP: Mailchimp for WordPress) does the same job, i.e. updating from WordPress user list to Mailchimp list (on your server), then are there any reason to keep MailChimp User Sync?
Shouldn’t I just delete it, if all I used it for was to keep WordPress user list synched with Mailchimp list?
Or do I loose any of abovementioned functionality by deleting MailChimp User Sync?
