Slack vs Salesmsg: at a glance
What is Slack?
Slack is rebuilding its app platform around agents, not bots.
Slack's developer platform is running two tracks at once: a modernization sweep through its SDK layer and a steady buildout of agent-specific primitives. The SDK track is shipping breaking major versions — Bolt for JS v5 and a coordinated wave of Node Slack SDK majors — that drop legacy features and move onto native web APIs. The platform track keeps adding pieces aimed squarely at agent apps rather than classic message-posting bots.
What is Salesmsg?
Business-texting platform reorients around AI agents and CRM depth.
Salesmsg is a business SMS/MMS and calling platform whose recent releases are dominated by AI agents (booking, calling, and general automation) and deep CRM workflow integration with HubSpot and Salesforce. Monthly roundups also ship steady operational controls like credit tracking and permissions.

Slack is rebuilding its app platform around agents, not bots.
◆ Current state
Slack's developer platform is running two tracks at once: a modernization sweep through its SDK layer and a steady buildout of agent-specific primitives. The SDK track is shipping breaking major versions — Bolt for JS v5 and a coordinated wave of Node Slack SDK majors — that drop legacy features and move onto native web APIs. The platform track keeps adding pieces aimed squarely at agent apps rather than classic message-posting bots.
◆ Where it's heading
The center of gravity is shifting from apps that post messages to agents that hold context. Agent context injection, the new agent messaging experience, and the Slackbot MCP client together sketch a platform where third-party agents run inside Slack with real tools and awareness of what the user is looking at. The SDK major-version bumps are clearing deprecated surface — Workflow Steps from Apps, axios — to make room for that direction.
◆ Prediction
Expect the next releases to keep deepening the agent surface — more manifest-driven agent configuration and MCP tooling — rather than classic Block Kit or bot features. The clustering of agent-context, agent-messaging, and MCP entries over the last month points that way.
Salesmsg
6.3COMMS
Business-texting platform reorients around AI agents and CRM depth.
◆ Current state
Salesmsg is a business SMS/MMS and calling platform whose recent releases are dominated by AI agents (booking, calling, and general automation) and deep CRM workflow integration with HubSpot and Salesforce. Monthly roundups also ship steady operational controls like credit tracking and permissions.
◆ Where it's heading
Salesmsg is moving from a texting tool to an AI-agent execution layer that lives inside the CRM: agents book meetings, run call flows, and act on live data, while admins get tighter governance. The MCP release extends this to any external AI assistant.
◆ Prediction
Expect the AI agents to take on more of the outreach and scheduling workflow end to end, and continued expansion of CRM object coverage so texting reaches any record type.
