We’ll email you to let you know when a paid survey is coming and you’ll receive a second email with your personalised link to the survey. If you don’t finish it all in one go, you can save it and come back to it later. All of the surveys are usually open for one week, but we’ll let you know the deadline when we send you the survey.
Sometimes we’ll send shorter surveys if we need a little more information to help us understand what we’re seeing in the trials data. These will be emailed to you and won’t be paid, so they won’t have a deadline.
