Rules

Rules sort mail for you. Each rule has conditions (from, to, subject, body, attachment, importance) and actions (move, categorise, flag, mark read, set importance, delete). Rules run on new mail, or on demand.

Calendar

Click or drag over empty time and type to make an appointment.
Drag an appointment to move it, or drag its edge to resize it. Hold Ctrl to copy it.
When you change a repeating item, MailCraft asks whether to change just this one or the entire series.
Use Find a Time to see when the people you invite are free.
With a Microsoft 365 account, changes go to the server straight away, and meeting invitations, updates and cancellations are sent for you.

AI agents (MCP)

Every action in MailCraft is a command. The same commands drive the ribbon, the keyboard, the CLI, a JSON control channel and an MCP server.

mailcraft --sample --control 7991          # the app, with a control channel
mailcraft-cli mcp --connect 127.0.0.1:7991 # an MCP server connected to that window
mailcraft-cli mcp --sample                 # or headless, with no window

See the MCP guide and the control protocol.
