My website is integrated with WooCommerce, and we have a large number of profiles from WooCommerce. However, these profiles have never subscribed to us because our website didn't previously ask for subscription consent.
We also have subscriptions through Mailchimp. combining WooCommerce profiles with MailChimp profiles, the total would be over eight thousand individuals. However, the number of subscribers in Mailchimp is only four thousand. This means we can only perform email marketing for these four thousand subscribers.
Before we pay for all eight thousand profiles, I'd like to know if there's any way to avoid paying for the additional four thousand subscribers. (I've searched, but couldn't find the right article for this...)
