On his site has posted parts one and two of a series showing how to build a chatbot that can help provide more direct interaction with your users via a "newsletter" feature.

Since the beginning of the year, I am working on a new project of mine. It's a book called Build Chatbots with PHP. Follow the link to find out what it is about and who it is for.

More interesting to us is the newsletter, to which you can subscribe on the book's website. About once or twice a month I will send out an email with news on the development of the book.

He starts part one by outlining the general plan and functionality for the bot and its integration with Facebook. The tutorial then walks through the installation and configuration of the BotMan Studio project. It also shows the setup of the application on the Facebook service and how to connect it to the BotMan application. He walks through the setup of a few commands to welcome the user and start the conversation. Part two continues the process showing how to store the user and subscription information and how to send the newsletter notifications. He also makes some suggestions of extra functionality you might want to add like a typing indicator, a "fallback" for unknown commands.
