You can automate email tasks using AI-powered tools, specifically by pairing OpenAI's GPTs with Zapier's AI actions. This allows users to create custom email assistants that can connect to various apps like Gmail or Microsoft Outlook, streamlining business communication and reducing inbox clutter. The process involves setting up a Zapier account, creating custom GPT instructions, configuring the assistant with web browsing and image generation capabilities, and adding necessary actions to bring all the connected apps together. Once configured, users can test their email assistants by sending emails through them, refining their setup as needed, and sharing their custom chatbots with others.
