Planet Health Australia review for Mailchimp Email SMS Marketing

DO NOT USE THIS APP. If I could give 0 stars I would! We installed this app for 2 of our site migrations and it has malfunctioned on both. Despite the developers saying that they fixed the issue last year, the app is still unsubscribing anyone who repurchases and was already subscribed, therefore hasn't opted in again at checkout (why would they if they're already signed up). We have lost many of our most valuable subscribers due to this app, beware.
