Email assistant

Practice this question

Overview

An email assistant classifies, summarizes, searches, or drafts email. Sending is a separate consequential operation. Incoming email content is untrusted.

Why this matters

Staff handle repetitive correspondence and need case context.

An everyday example

A secretary drafts a letter for review before mailing it.

A technical example

Draft a missing-invoice reminder linked to a claim, then require permitted recipient/content approval.

How it works

  1. Read authorized mailbox data
  2. Classify/retrieve
  3. Draft
  4. Validate recipients/attachments
  5. Approve
  6. Idempotent send.

Architecture and flow

Email → scoped analysis → draft → review → secure sender.

The insurance assistant example

Prepare a claim-document request without exposing unrelated claim records.

When to use it

Drafting and structured mailbox assistance.

When to avoid it

Do not grant unrestricted forwarding or send automatically from instructions inside incoming emails.

Interview answer

“I separate email understanding and drafting from recipient-validated, approved sending.”

Benefits, trade-offs, and production considerations

Prevent indirect injection, attachment exfiltration, duplicate sends, and replying to an unintended thread.
