ChatGPT Ads expands its reach and adds sponsored conversations
On September 23, OpenAI began rolling out ChatGPT Ads in Indonesia, Malaysia, the Philippines, Singapore, Thailand, Vietnam, and Taiwan, bringing its announced footprint to more than 60 countries. OpenAI specifies that self-service Ads Manager access is for eligible businesses and that ads appear only on Free and Go plans.
Sponsored Agents, introduced on September 16, let users choose a clearly labeled conversation with a business-sponsored agent after clicking an ad; these conversations are separate from ChatGPT’s independent answers and the original chat. The same OpenAI release adds an Ads Manager plugin for creating, updating, and analyzing campaigns in ChatGPT, plus suggested copy and imagery in Ads Manager that advertisers can review and edit.
HubSpot adds campaign management and conversion feedback
HubSpot’s ChatGPT Ads integration guide documents campaign creation, performance reporting, and attribution of contacts and deals, with auto-tracking adding UTM parameters to ad URLs. The connection remains labeled beta, with Super Admin opt-in, an active ChatGPT Ads account, and Ads publishing permission required.
HubSpot also documents conversion-event syncing that sends form submissions or contact lifecycle-stage changes to ChatGPT Ads for targeting optimization. Its requirements include permission to share each contact’s data, and only record updates occurring after the conversion event is created count toward optimization.
Campaign agents: drafting, planning, and live campaign decisions
HubSpot Campaign Agent prepares drafts for review
HubSpot’s September 16 documentation says Campaign Agent uses campaign goals, audience information, briefs, performance history, brand identity, and CRM data to prepare plans and assets. The documented entry point is Marketing > Marketing Studio: select or create a campaign, open the AI panel, and enter a prompt; campaigns and assets are not automatically published. A Super Admin must enable the relevant AI settings, and certain features require HubSpot Credits.
Salesforce names October for Campaign Agent availability
Salesforce’s September 14 announcement describes an agent that assembles audiences, channels, and content, then personalizes messages and prioritizes or suppresses competing campaign sends for individual customers. Its workflow description puts marketer review and approval before publication and describes subsequent adjustments to budget, channel mix, offers, and send timing. The release names October for general availability in Marketing Cloud Next without specifying a rollout day.
Demandbase, Madison Logic, and Adobe add campaign capabilities
These releases address different parts of campaign work:
| Product | Date | What the company announced | Access information in the source |
|---|---|---|---|
| Demandbase Mojo | September 15 | Audiences, briefs, and campaign execution across connected advertising and CRM tools; tracking and audience corrections presented for approval | Launch announced; the release does not give full account eligibility or pricing |
| Madison Logic AI Planner | September 9 | Audience priorities, channel mix, and budget recommendations for account-based campaigns, with validation and approval controls | Immediately available as a core feature for all Madison Logic clients |
| Adobe Marketo portfolio | September 28 | Marketo Optimizer for coordinated engagement, Qualifier for prospecting and qualification, and Coworker for assisted workflow building | Products introduced; the article does not specify a general availability date for each |
Meta Muse and OpenAI dots connect marketing work across apps
Meta introduced Muse for Small Business on September 29, connecting Facebook and Instagram business accounts, Meta ad accounts, and tools including Canva, Klaviyo, Shopify, and Slack. Its announcement includes campaign analysis and drafting and says publishing, sending, and spending require approval.
OpenAI introduced dots on September 29: persistent agents with cloud computers and connected apps, accessible through ChatGPT, Slack, and Teams. Dots began rolling out to Pro and Business Premium users in eligible markets, with an administrator-enabled beta for Enterprise users. OpenAI separately describes specialist dots for organizational responsibilities, including email marketing, as focused enterprise pilots.
Google adds measurement tools and previews AI Max reporting
Google’s September 10 measurement update adds Data Manager integrations with Google Analytics and Display & Video 360, a universal Data Manager API, and diagnostics for data issues. Its Data Strength Uplift Metric calculates additional conversions recovered by first-party data setup, while the same release makes Meridian GeoX globally available for geographic experiments and calibration of marketing mix models. The metric describes improved conversion reporting; GeoX is the separate tool for testing causal advertising effects.
On September 23, Google expanded AI Brief’s closed beta to Dutch, French, German, Italian, Japanese, Portuguese, and Spanish, allowing advertisers to give AI Max business, audience, and messaging context in natural language. It also announced a unified Search ads journey report connecting triggering search terms, displayed creative, and landing pages; further details and availability were promised later in 2026.
Microsoft Advertising connects to HubSpot
HubSpot’s Microsoft Advertising connection guide, updated September 18, documents management and reporting of existing Microsoft campaigns in HubSpot and lists availability across all HubSpot products and plans. The connection requirements specify individual advertising accounts, HubSpot ads publishing access, and Super Admin access in Microsoft Advertising; accounts managed under a Microsoft customer account must be connected individually.
Creative releases: images, voice generation, and interactive avatars
ChatGPT Images 2.5 adds targeted editing tools
OpenAI released ChatGPT Images 2.5 on September 8, with sketch references, templates, comments for focused edits, and availability across ChatGPT, ChatGPT Work, and Codex. OpenAI says the model improves detail preservation and editing consistency and introduces GPT-Image-2.5 Flare and Sunburst in the API, with Sunburst positioned for more precise creative workflows.
Google and ElevenLabs expand voice production
Google’s September 23 Gemini 3.8 TTS release introduces Flash TTS and Flash-Lite TTS, including voice design and line-by-line direction of delivery. Its availability section lists developer access through the Gemini API and Google AI Studio, Flash-Lite rollout in Google Vids, and enterprise API availability as coming soon.
ElevenLabs’ September 28 changelog makes Eleven v4 and Eleven v4 Turbo available, describing expressive speech and improved voice cloning across more than 90 languages. Its documented distinction places v4 in content creation and long-form audio, and Turbo in real-time agents and interactive applications.
Gemini Live Avatar adds a visual interface
Google introduced Gemini 3.8 Live with Live Avatar on September 24, combining dialogue with generated video for interactive walkthroughs and other conversational experiences in Gemini Enterprise. Its custom avatar capability can preserve a reference image’s likeness or brand styling and is available through enterprise allowlisting.
AI adoption research and a synthetic-performer disclosure law
WFA’s September 30 research reports generative or agentic AI use at 96% of surveyed major brand owners, based on 54 senior respondents from 46 companies. In that survey, 54% reported AI use for media buying or optimization, 48% for strategy and planning, and 46% for workflow automation or autonomous agents. WFA also reports 20% testing paid advertising in large language models, with 4% placing it among their top priorities; these figures describe the surveyed brand owners.
California approved SB 1050 on September 16, with chaptered text published September 17. The text sets a disclosure requirement for advertisements prominently featuring a defined synthetic performer: an AI-created figure or voice giving a realistic impression of a human performance, without being recognizable as an identifiable natural person. Its exceptions include AI used solely for language translation of a human performer or accessibility features.
