Slack vs Trumpia
A side-by-side editorial comparison of Slack and Trumpia — release velocity, themes, recent moves, and the top alternatives to consider.
Slack vs Trumpia: at a glance
What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
What is Trumpia?
Trumpia's feed is an SMS marketing blog with no product releases in it.
Every recent entry is educational or promotional content about SMS marketing — campaign prerequisites, KPI lists, an emoji guide, opt-in psychology, RCS-to-SMS instructions. None describes a change to the Trumpia product. One post appears twice under the same title with slightly reworked text.

Slack
6.3COMMSCOLLAB
Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
Trumpia
5.0COMMS
Trumpia's feed is an SMS marketing blog with no product releases in it.
◆ Current state
Every recent entry is educational or promotional content about SMS marketing — campaign prerequisites, KPI lists, an emoji guide, opt-in psychology, RCS-to-SMS instructions. None describes a change to the Trumpia product. One post appears twice under the same title with slightly reworked text.
◆ Where it's heading
This is a content-marketing channel rather than a changelog, so it carries no signal about where the product is heading. The consistent editorial theme is defending SMS against social media and RCS as a reach channel, which indicates where Trumpia positions commercially rather than what it is building.
◆ Prediction
The feed will keep producing SEO content on SMS marketing fundamentals. Any read on product direction would have to come from a different source than this one.
