Bot Libre allows a bot to be connected to email. This lets you create a bot to be your first tier of support or customer service for your business. The bot can answer common user questions and defer more difficult questions to your second tier support.
Connecting a bot to email can also be used to let your bot send email notifications from scripts, such as when a user wishes to escalate an issue from live chat. Email also provides a novel way to let people interact with your bot.
