Send us Fan MailMeta has put its ad system in open beta behind an MCP server and a CLI, letting ChatGPT, Claude and any other MCP-aware agent read reports, build campaigns, manage catalogues and run signal diagnostics across Meta ad accounts in natural language. The unit of work for paid social is shifting from the UI to the prompt.YouTube has rebranded BrandConnect as YouTube Creator Partnerships and folded it into Google Ads and Display & Video 360, with Gemini doing the discovery across more than three million YouTube Partner Program creators.

Influencer marketing has been pulled inside the performance stack.OpenAI has launched Workspace Agents — a successor to Custom GPTs that runs inside ChatGPT Business and Enterprise and plugs into Slack, Salesforce, Google Drive, Microsoft 365, Notion and Atlassian. Free until 6 May, then credit-based pricing kicks in. This is the first time OpenAI has shipped an enterprise automation runtime, not a chat product.GPT-5.5, GPT-5.4, Codex and a new Bedrock Managed Agents product are now in limited preview on AWS.
