Question: Can you use the same poll multiple times?
Answer: At the moment, there isn't a way to let people answer the same poll multiple times but we do have two suggestions.
Suggestion 1: You can clone polls to use a new one each week without having to re-do it each time. Here is an article about cloning campaigns: http://help.pastorsline.com/en/articles/2365687-how-to-clone-your-campaigns
Suggestion 2: Use multiple triggers - https://help.pastorsline.com/en/articles/2194708-ninja-trick-using-multiple-keywords-to-trigger-additional-automation
