What it does

This skill teaches an AI agent running inside the Paperclip platform how to use the email inbox that has been assigned to it. The agent can list its assigned inboxes, read the email thread attached to a task, send a new email or a reply, and check whether a sent message was delivered. It is written with strict rules: email goes out only through the official commands or API, replies reuse the original conversation, every send carries an idempotency key so retries do not duplicate mail, and the agent never handles the email provider's keys itself.

Great for

  • Teams running Paperclip agents that handle customer or vendor email tasks
  • Operators who want an agent to reply to inbound email under company-set permissions and budgets
  • Developers configuring Paperclip AgentMail connections who need a reference for the agent-side workflow

Skip it if

  • Anyone wanting a general email client or personal inbox outside Paperclip, since it only works with an inbox assigned through Paperclip's AgentMail connection
  • Use with sensitive or high-stakes correspondence without human review, because the agent can send real external email that cannot be recalled once queued

Try asking

  • “Read the email thread attached to my current task and summarise what the sender is asking for.”
  • “Reply to the latest message in this conversation, keeping the original thread intact.”
  • “Send a new email from my assigned inbox to the vendor about the delayed invoice, with the report attached.”
  • “Check whether the email I sent earlier was actually delivered.”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • State the recipient, subject and purpose clearly, since sent email is external and cannot be recalled.
  • Ask the agent to summarise a thread before drafting a reply so you can check its understanding of the sender's request.
  • Keep attachments and CC/BCC lists explicit in your instructions; the skill only includes them when named.
