Slackforce Surfaces, Lightning, and Big Mode

Day 1 introduced Slackforce as a companion surface. Day 3 filled in the useful detail: what is available now, what waits for October, and where Slackbot appears outside the channel.

The important change is the output. Ask Slackbot for something useful and the result can be an interactive interface that the team pins, filters, and uses from the same place.

Excalidraw schema: Slackforce stack

Slackbot in Lightning places that conversation next to the record. Big Mode provides the full-screen workspace for research and writing, then lets you push the finished work into a Surface.

Slack states that Surfaces are available now for workspaces with Slackbot on Enterprise+, Business+, Pro, Legacy, and Free Teams. Live-data refresh begins in October. Slackbot in Lightning is available now on Business+ and Enterprise+, with Flex Credits for other Salesforce customers. Big Mode is available now. Rollout timing, plan, and extra-license requirements can still affect access, so admins should verify the exact entitlement.

Slack Code, Channels, Voice, Video, Frontline

Slack Code is available now on all Slack plans. Its code channels bring conversation, plans, diffs, and live preview tabs together. Partner agents need separate access. During Dreamforce week, Slack also named Cedar, Coderabbit, Datadog, Factory, Lovable, Mistral, NanoClaw, Replit, Rhythms, and Snowflake, among others (Slack-stated).

Slackbot in Channels is an early pilot. A team can tag Slackbot in a channel and build on the answer together.

The roadmap is separate from what is live. Two-way Voice is coming later this year. Video generation is also coming later this year or this fall. Slack Frontline is in preview, with GA planned for a future release. Slack labels each of those stages clearly.

Marketing: Campaign Agent and the October GA cluster

On the marketing side, Campaign Agent is the concrete Day 3 move. The marketer provides goals and guardrails. Campaign Agent assembles the audience, content, and channels, personalizes the work, then prioritizes sends across campaigns according to customer intent.

Excalidraw schema: Campaign Agent loop

Campaign Agent is scheduled for GA in October 2026 in Marketing Cloud Next (Salesforce-stated).

Salesforce places the same October cluster on Marketing What’s New: Account Discovery Agent, Account Based Recommendations, Headless Marketing (MCP), Adaptive Web Quick Setup, Personalized Paths in Flow, Mobile Flash Sending, Data Guardian, and Budget Optimization. Event Management is tagged for GA in November 2026.

Palmata, the Contentful AEO story, sits beside that cluster. It covers brand visibility in answer engines, competitor comparison, and suggested content edits. Salesforce’s editor note says the Contentful acquisition closed on 1 September 2026.

Access can still depend on region, customer agreement, rollout timing, plan, or packaging.
