I run a support inbox and a personal one, and the morning triage used to eat my first hour. These three prompts cut it to about 20 minutes. Swap in your own senders and folders and they work as-is.
[Claude]
[Claude] Here are my inbox rules: clients get replies within 2h, vendors within 24h, newsletters get archived. Below is a pasted list of 40 subject lines plus senders. Sort them into: reply now, reply today, archive, delegate. Output a markdown table with sender, subject, bucket, and a one-line suggested reply opener. Flag anything from a domain I have not emailed before.
[ChatGPT]
[ChatGPT] Rewrite this draft email so it is 60 words or fewer, keeps the ask in the first sentence, and drops hedging phrases like “just wanted to” and “circling back”. Keep my tone: direct but friendly. Output the rewritten email, then a two-item list of what you cut and why.
[Cursor]
[Cursor] Write a Python script that reads an exported Gmail mbox file, groups messages by sender domain for the last 30 days, and outputs a CSV of domain, message count, average reply latency in hours, and unread percentage. Sort by message count descending. Use the standard mailbox library only, no API keys. Include a docstring and a sample run command.
