Native AI credits and a steady drip of MCP integrations turn Missive into a credible AI inbox.
Missive is releasing on a roughly bi-weekly cadence, with most of the energy going into the AI assistant: tool-call introspection, native AI credits as an alternative to BYOK, MCP integrations with Todoist and ClickUp, and an Activity feed that lets the assistant analyze inbox/team-inbox/label state on demand. Calendar UX got drag-to-move and resize, Analytics gained inline time-series charts, and OpenAI EU residency support was added for European customers.
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.

Calendar UX got drag-to-move and resize, Analytics gained inline time-series charts, and OpenAI EU residency support was added for European customers.
The product is methodically converging the team-inbox surface with an AI assistant that has actual context — not just a sidebar chatbot but one that can mention specific labels, fetch conversations, and reach into external task systems via MCP. The AI Credits launch is the strategic move; it ends the BYOK-only friction and starts building a new revenue line on inference markup. Continued MCP integration additions suggest more partner connections ahead.
Expect more MCP integrations (Linear, Asana, Notion are obvious next targets), AI Credit consumption analytics for admins, and likely a paid AI tier or assistant-only seat type once the credit usage data is in. Calendar will probably see more two-way sync polish given the drag-to-move foundation.

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