The latest addition to Pool is Engagement! Keep track of how engaged your research participants are across all your studies, or by segment. See a quick Overall Engagement metric at the top of Pool and drill down to see how you're doing on participants opening emails, clicking links, and hopefully not very many bounces. :-)
We've radically improved the design and branding options for your incentive redeem links. Try it from incentives >> emails & redeem pages >> redeem pages >> branding & colors
Let's say you ask the same opt-in question across 30 screeners and 30 uploads in Pool along the lines of "Are you interested in participating..." You can now create one filter that looks for any question with the word "interested" containing the answer "yes," and have an automatically updating segment to keep track of your opt-ins from multiple sources. Gigantic time-saver.
