Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sending-mailbox-management

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent creates mailboxes on a sending domain the workspace owns, runs warm-up and the gradual volume ramp (5 to 40 a day), checks the remaining allowance and reads reply threads and delivery events. A mailbox is a monthly credit charge, and sending itself goes through the sendEmail action. You get ready mailboxes and readable reporting.
