Good but Limited

Works well for basic email setup & easy to connect with Mailchimp. UI is simple. But needs more flexibility in forms. Overall, a good plugin. tnx 👍

Simple Mailchimp Connect

Good plugin for connecting Mailchimp with WP. Setup was pretty easy and forms started collecting emails without much hassle. UI is clean too. A few more design options would be nice, but overall works
