There are a few different options worth checking out, including SurveyMonkey, SurveyGizmo, Typeform, Fieldboom and AskNicely.

Fieldbloom makes it easy to design beautiful surveys and online forms in less than 5 minutes.

You can analyze responses one-by-one and also tag them with labels, star them and mark them as read or unread (just like Gmail). You can also use the simple but powerful reports to understand trends in the feedback you’re receiving.
