Constant Contact's feed is a small-business marketing blog with no product news in it.
The feed runs several evergreen guides a day and none of them report a product change. The recent set is vertical and channel coverage — event marketing, Google Business Profile optimization, healthcare marketing, digital asset management, small business websites, lead generation — plus a competitor comparison page aimed at Brevo users. Occasional original data appears, such as the 2024 Small Business Now finding that most owners have an hour or less a day for marketing, but it serves the content rather than any release.
Surfer shipped the MCP server its May API release said it was building toward
Surfer has spent 2026 collapsing the distinction between ranking on Google and being cited by AI models, and the last month completes the delivery path it laid out in May. The API rebuild was described at the time as the foundation for an MCP server; that server is now in beta, exposing the Content Editor lifecycle, Auto-Optimize, SEO and AI Search guidelines, AI Tracker visibility data and Recommendations as tools an agent can call. Alongside it, Recommendations began consuming AI Tracker signals to prioritise which mentions to earn and which sentiment to fix.

The editorial strategy is breadth: cover every vertical and every adjacent marketing task a small business might search for, then convert on comparison pages against competing platforms. The topics reach well past email into local search, asset management, and website conversion, which suggests the company wants to be found for the whole small-business marketing problem rather than the mailing list alone. Whether the product is expanding in the same direction is not observable from this feed.
The vertical guide series will keep extending to new industries and the competitor comparison pages to new rivals; release information will continue to be absent here.

The direction is Surfer as a capability an agent uses rather than an application a writer opens. Everything shipped since May points that way: the API first, then the agent interface, with the scoring and guideline logic being the part that stays proprietary. The AI Tracker work suggests the second front is measurement — owning the data on whether models cite you, which is what makes the recommendations worth calling in the first place.
Expect the MCP beta to move to general availability with the Agentic Surfy work the May release named, and for AI Tracker data to keep spreading into the surfaces that already existed.
