Short answer — Yes – if they’re a collaborator on your survey.
Longer answer — Here’s how previews work on doopoll:
If you created the survey, you can preview it by clicking ‘Preview’ on your editor. Here’s a link to preview your most recent survey. You can answer the questions and run through it as often as you like and it won’t affect the results in your report.
If you invite your team mates to collaborate on your survey with you by clicking ‘Add Collaborators’ – they’ll be able to do the same thing.
If the person you want to preview the survey isn’t a doopoll user yet, they won’t be able to see the Preview screen. If you would like to add them to your account, you can do that by clicking here
