The daily briefing for AI marketers, growth hackers, and operators.

TL;DR — OpenAI began serving ChatGPT ads inline to signed-out users, expanding inventory beyond the original logged-in audience (Search Engine Land). The minimum buy-in for pilot advertisers dropped by 75% to $50,000 from $200,000, though early spend is capped by low frequency. Ads appear directly inside chat responses rather than as traditional banners. Tactical implication: Pilot advertisers should re-pace budgets to capture growing inventory, while non-pilot brands must audit product feeds and FAQ pages for answer-engine citations.

TL;DR — Anthropic moved Claude Cowork to general availability for all paid plans, adding role-based access controls and group spend limits (The New Stack). Early adoption extends beyond engineering to marketing and ops teams utilizing the new usage analytics API and 1 native Zoom MCP connector. The platform enables shared, persistent workspaces across macOS and Windows environments. Tactical implication: Run a 2-week Cowork pilot on campaign QA workflows and use the Analytics API to prove usage before expanding seats.

TL;DR — OpenAI is testing an always-on agent platform codenamed Hermes that enables users to create 24/7 persistent teammates with custom skills (TestingCatalog). The beta feature integrates directly with the existing Workflows builder, moving beyond 1-off task runners to continuous autonomous operations. Placeholder examples suggest users can orchestrate multiple functional agents simultaneously. Tactical implication: Map existing marketing workflows into discrete agent roles now to prepare for orchestration when the Hermes platform reaches general availability.

TL;DR — Google Ads added view-through conversion optimization to Demand Gen campaigns, allowing buyers to bid directly on YouTube view-throughs instead of just clicks (Search Engine Land). Google also extended its Commerce Media Suite to Demand Gen inventory, enabling retailers to target high-intent shoppers using 1st-party catalog data. This integration spans across YouTube, Discover, and Gmail. Tactical implication: Switch video-heavy Demand Gen campaigns to VTC optimization this week and upload your product feed to Commerce Media Suite before the next retail push.

TL;DR — Salesforce discusses new challenges in email marketing and strategies to overcome them. Trend: Increasing email volumes demand more personalized content. Play: Use AI to segment audiences and tailor email content for higher engagement rates.

TL;DR — Microsoft introduced AI Max for Search campaigns and updated 3 core areas—measurement, commerce, and media—to track how brands appear in AI-generated answers. The platform updates shift focus from traditional clicks to securing citations within conversational interfaces. Tactical implication: Audit 10-15 of your top products using the Universal Commerce Protocol in Merchant Center to ensure AI agent discoverability.
