Chatfuel is a very popular building platform, used by Forbes, TechCrunch and several NBA and NFL teams. One of the easiest free chatbot creation sites offers an easy interface and many different plugins. For example, you can integrate your bot with Zapier, Google Calendar, Instagram, Slack, YouTube, and many other apps. The broadcast feature allows you to send personalized messages to user groups. Since Chatfuel only works on Facebook Messenger and Telegram, you will need to get authorization from your contacts before you start broadcasting. After your chatbot engages at least three users, you will gain access to the Analytics panel. There you can analyze the bot’s work and gain useful information for future upgrades.
