What is Missive?
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.
What is Subsplash?
Subsplash is wiring automation and AI through the church admin stack it already owned
Workflows came out of beta in mid-July with per-step email automation, then immediately gained completion notifications for team leaders. Around it, the administrative surfaces are being rebuilt in sequence: Transfers and reconciliation now tracks who reconciled what and when, Groups gained member limits with a Full badge and finder filters, and event managers can register guests and waive payments directly from the dashboard. The AI line is filling in too — Trends AI added media and campaign data on top of giving, people, attendance and groups, following the natural-language People Assistant in May.
Missive vs Subsplash: editorial side-by-side
Missive
5.0COMMS
Native AI credits and a steady drip of MCP integrations turn Missive into a credible AI inbox.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

Subsplash is wiring automation and AI through the church admin stack it already owned
◆ Current state
Workflows came out of beta in mid-July with per-step email automation, then immediately gained completion notifications for team leaders. Around it, the administrative surfaces are being rebuilt in sequence: Transfers and reconciliation now tracks who reconciled what and when, Groups gained member limits with a Full badge and finder filters, and event managers can register guests and waive payments directly from the dashboard. The AI line is filling in too — Trends AI added media and campaign data on top of giving, people, attendance and groups, following the natural-language People Assistant in May.
◆ Where it's heading
Two threads run in parallel and are starting to meet. One is turning manual church-admin chores into configured automation — workflows that send their own emails, notify on completion, and enforce group capacity without a staff member watching. The other is putting a natural-language layer over an increasingly complete data set, which only becomes useful once giving, attendance, media and campaigns all live in the same place. Recent releases have been closing the gaps in that data set.
◆ Prediction
The obvious convergence is Workflows becoming triggerable from the data — a Trends AI segment or People Assistant query that drops matching people onto a workflow board automatically. Reconciliation gaining an export or accounting-package integration is the other near-term candidate given how much structure was just added to Transfers.
