I'm struggling with how I can do the below (under my current personal subscription):I want to import subscribers from a CSV file, then "divide them into categories" and send each category a different copy of the posts I post! All ofc are free subscriptions, but each will receive a different post.
Example: I have a set of emails named "Founders and CEOs" and another set of emails named "IT people". I want a different newsletter to be delivered to each category as per the set of emails I already have. When I add the subscribers manually, there's only one option for one email set, and not more.
If I have to upgrade my wordpress account, I will (but I don't prefer it ofc), what kind of plugin…etc. I'll need to install in order to achieve the above?
