Recommend email subscribe plugin?

[AMcDermott]

I'm looking for a well supported, free or single-payment, email subscribe plugin for WordPress. Once that creates a nice lightbox, looks decent, strong preference for something that is responsive & mobile friendly. Mailchimp or Aweber support required.

What are my options? Any recommendations?

Have you looked at pop up domination?
