I've been using Mailchimp for a while and I'm very confused with the software. Lists changed to "Audience", and it seems they want me to segment my audience using tags instead of having separate lists which just makes things more confusing for me. I guess they are moving away from "email" software to more general "marketing" software. Also the editor is surprisingly bad.

I'm planning on experimenting with https://www.mailerlite.com to see if it's more to-the-point.
