What is Salesmsg?

Salesmsg Reviews can now trigger follow-ups automatically based on a customer's latest rating.

Salesmsg upgraded Reviews: follow-ups can fire automatically based on a customer's most recent rating, reviewers can be messaged in bulk or answered directly from review analytics, and results can be exported. It follows an official MCP server listed with Claude and ChatGPT, call tracking and AI call scorecards, and recurring NPS surveys that enrol contacts in automations.

What is Slack?

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

Salesmsg vs Slack: editorial side-by-side

S5.0

Salesmsg Reviews can now trigger follow-ups automatically based on a customer's latest rating.

◆ Current state

Salesmsg upgraded Reviews: follow-ups can fire automatically based on a customer's most recent rating, reviewers can be messaged in bulk or answered directly from review analytics, and results can be exported. It follows an official MCP server listed with Claude and ChatGPT, call tracking and AI call scorecards, and recurring NPS surveys that enrol contacts in automations.

◆ Where it's heading

Salesmsg is connecting feedback (surveys, NPS, reviews) to its texting and calling automations, so a customer's score decides what happens next. Alongside that, AI agents for calls and texts and the MCP server extend who, or what, can act on those conversations.

◆ Prediction

Expect review and survey scores to feed the AI texting and calling agents directly, and more CRM sync for review data.

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

◆ Current state

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

◆ Where it's heading

The install requirement moving back up is a distribution decision arriving in the middle of a platform push, and the two point the same way. Slack is making it easier to build agents and harder to list one, which favours developers who already have distribution — existing workspace tools and vendors — over a new app hoping the Marketplace supplies its first users. Combined with the assistant deprecation and the Agent Sessions API, the platform is narrowing on one agent surface and one class of builder rather than widening the funnel.

◆ Prediction

The threshold is described as a return from a temporary lower bar rather than a new policy, so the open question is what replaces the Marketplace as the discovery path for an app that cannot reach ten workspaces on its own. These entries do not answer it.
