What is Superhuman?
Superhuman's MCP now lets Claude and ChatGPT attach files, set reminders and share threads.
Superhuman is a premium email client building a calendar, team comments and AI around its mail core. On 11 November its Mail MCP gained four abilities in Claude, ChatGPT and other AI tools: setting follow-up reminders, sending attachments, using private and team snippets, and sharing threads for team comments. The MCP stays on Business and Enterprise plans, a week after a team admin console reached every plan.
What is Salesmsg?
Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.

Superhuman
5.0COMMS
Superhuman's MCP now lets Claude and ChatGPT attach files, set reminders and share threads.
◆ Current state
Superhuman is a premium email client building a calendar, team comments and AI around its mail core. On 11 November its Mail MCP gained four abilities in Claude, ChatGPT and other AI tools: setting follow-up reminders, sending attachments, using private and team snippets, and sharing threads for team comments. The MCP stays on Business and Enterprise plans, a week after a team admin console reached every plan.
◆ Where it's heading
Superhuman is making its mail features callable from outside AI assistants rather than only from its own app. Each MCP addition maps an existing Superhuman feature, such as reminders, snippets or shared comments, onto a tool an assistant can use, with sharing gated on the user's confirmation. Keeping the MCP on paid team plans ties it to the admin and usage reporting shipped the week before.
◆ Prediction
More Superhuman features exposed through the MCP is the likely next step, with calendar and Auto Labels the obvious gaps; the entries do not show whether the MCP will reach lower plans.
Salesmsg
6.3COMMS
Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
◆ Current state
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
◆ Where it's heading
With AI now able to send messages, Salesmsg is adding the brakes: an organization-wide stop switch and weekly reports on what its AI agents did. Calling features keep catching up with texting, with queue callbacks and recording rules.
◆ Prediction
Expect more controls over what Sherpa and AI agents may send, such as per-agent limits or approval rules, alongside further HubSpot call-data sync.
