I used the landing page analysis feature for a page in Spanish, and it gave me many insights into things I needed to improve; the output was in English, but it was very helpful to me. I also used the email marketing option, and I liked the output (it was in the desired language - Spanish). A valuable addition would be if Superline had the capability to create the questions for surveys, to gather customer opinions about your products or to assist in other marketing research efforts. All in all, I see a lot of potential.
