Hello, I need a plugin which has a sign-up-to-the-newsletter system and which allows users to subscribe to the categories they choose from which they will get the latest articles weekly through e-mail. It should also have a pop-up so when a reader goes to a specific article from the category, it pops up and lets him/her subscribe to that category. I used Optin Monster + MailChimp, but it's TOO MUCH work as I have MANY categories and everything must be done manually. Any suggestion? Paid plugins are welcome as well. Thanks!
