A few years ago, you had to use a special bot to run a poll on Telegram. Now you can easily do that yourself in two clicks. Hit the Menu icon and select “Create Poll.” Write your question and add up to 10 options. Running polls is a powerful strategy for getting feedback from your audience. If you’re considering the possibility of modifying your channel in any way, be sure to ask your subscribers’ opinions first.
