HubSpot users can now connect Microsoft Advertising, the company said in its September product update on the Microsoft Advertising blog. Advertisers can reach HubSpot contacts across Bing, Copilot, Outlook and Xbox. A newly captured lead can set off a follow-up step defined in HubSpot, for example routing it to a salesperson or sending a nurture email. Ad clicks tie to contacts and deals, so pipeline and revenue can be compared by channel.
LinkedIn company lists now hold up to 10,000 company names, up from 1,000. Lists work with LinkedIn profile targeting in Search and Audience campaigns. They are available globally in supported markets, though the consumer data behind them leaves out users in the EEA, the UK and Switzerland.
Microsoft also tells advertisers that integrations must be on the REST API by January 31, 2027 to keep running.
B2B teams running account-based programs can load full target-account lists in one pass, while anyone with SOAP-based tooling should schedule the REST migration well ahead of that date.
