Unlock professional, HTML-formatted emails from your Microsoft Copilot Studio agents instead of ugly, plain-text walls of text. In this video, AJ Ansari shows you step-by-step how to turn Copilot Studio emails from basic, unformatted blobs into polished, branded messages with tables, colors, banners, signatures, and more. Whether you’re using the Office 365 Outlook MCP server, the standard Office 365 Outlook connector, or Gmail, you’ll learn how to get your agents to output real HTML that renders correctly in modern email clients. You’ll see three stages: 1. A simple agent that sends plain emails with no HTML. 2. A slightly improved agent that uses basic HTML formatting and a better signature. 3. A fully optimized agent using detailed system instructions to generate beautiful HTML emails with: Headline banners and icons Corporate colors and fonts Alternating table rows Proper currency formatting Highlight boxes for key information A professional signature We also walk through a real example where Copilot Studio pulls live customer data (customer name, salesperson code, and balance due) and sends it as a formatted HTML table with totals, so your emails look like real reports—not quick-and-dirty text dumps.
