### Which Claude model should I use for inbox triage prompts?
Sonnet 4.5 is the default for high-volume per-email classification (#2, #3, #4, #6) — fast and cheap enough to run against an entire morning pile in under a minute. Use Opus 4.7 for the synthesis-heavy steps (#1 briefing, #8 thread summarizer, #10 weekly retro) where holding many messages in working context matters more than latency. See Anthropic's model selection guide.
### Is it safe to paste my inbox into Claude?
Only after the redaction step. The redaction prompt at the top of this article is the load-bearing safety control — it replaces credentials, PII, and confidential blocks with placeholder tokens before any triage prompt sees the body. Anthropic's commercial terms document data handling, but a redaction step on your side is the right belt-and-suspenders posture for any inbox automation.
### Will Claude make up deadlines from email bodies?
Yes, unless constrained. Prompt #2's due_date_source field requires the model to return the exact substring of the email body that justified the deadline. If no substring exists, due_date is 'none stated'. The same exact-substring discipline appears in Anthropic's prompt engineering documentation.
### How does this compare to Outlook Copilot or Gmail's built-in summarizer?
Outlook Copilot and Gmail summaries do the equivalent of prompt #1 — and they do it well — but they don't chain. The 90-minutes-to-20-minutes gain comes from chaining briefing into action-item extraction into reply drafting with confidence flags routing the override cases.
### Can these prompts replace an executive assistant?
No. The prompts replace the read-and-classify labor; they don't replace the relationship judgment an EA brings — which messages need warmth, which board members hate one-line replies, which vendor is one nag away from being fired.
### What if my inbox is too large to fit in one Claude call?
Chunk by date range (last 12 hours, last 24 hours) and run #1-#4 per chunk. Sonnet 4.5's 200K context handles roughly 300-500 typical emails per call before chunking is required.
### Are the sample outputs synthesized or real?
Synthesized for illustration. The structure, constraint compliance, and confidence-flag behavior are representative of Sonnet 4.5 and Opus 4.7 outputs with the prompts as written; specific senders, threads, and dates are illustrative.
