To query łączy dane użytkowników z lokalnej witryny WordPress z danymi tych samych użytkowników w Mailchimp, używając adresu e-mail użytkownika jako wspólnego identyfikatora między obydwoma systemami.

Wynikiem będą dane email, name i lastname użytkowników pochodzące z WordPress, wzbogacone o pole location z Mailchimp.
