Sure do! I like to start with some qualitative research first to help get at any nuances in messaging, especially across different audience segments. Then, run a survey (max diff is a great technique) to understand what resonates most with your different segments. If you also have the budget and/or time, running your messaging by focus groups is another good option, so you can get a deeper understanding of their reactions and sentiment.
