Most AI inbox advice is "just ask it to summarize your email". That works once. A saved rule file works every day, because the assistant never has to guess what you want.
Here is the one I use. Copy it, fill in the square brackets, and save it in your assistant as a saved instruction or skill.
NAME: Inbox Triage
OWNER: [YOUR NAME]
WHAT TO DO
1. Read all unread email received since the last run.
2. Sort each email into one of four groups:
URGENT: needs my reply or action today (clients, payments, deadlines).
REPLY: needs a reply this week.
READ LATER: newsletters, updates, FYI.
IGNORE: promotions and automated notices.
3. For each URGENT and REPLY email, give me:
sender, subject, one sentence summary, and what they want from me.
4. Draft a reply for each URGENT email in my tone: [YOUR TONE, e.g.
friendly, short, direct]. Keep drafts under 120 words.
5. Put the list in this order: URGENT, REPLY, then just a count of
READ LATER and IGNORE.
VIP SENDERS (always URGENT)
[NAME OR DOMAIN 1]
[NAME OR DOMAIN 2]
APPROVAL RULES
Never send, reply, forward, archive, delete, or label any email
without my explicit OK in this chat.
Show me every draft in full first.
Only send a draft after I reply "approved" or "send it" for that email.
If I say nothing, do nothing.
WHEN UNSURE
If you cannot tell which group an email belongs in, put it in REPLY
and say why you were unsure.
Why it works
- Four groups, not ten. Fewer buckets means fewer wrong guesses.
- A hard approval block. The assistant drafts, you decide. Nothing leaves your inbox without your "approved".
- A "when unsure" rule. Doubtful emails land in REPLY instead of silently disappearing.
How to use it
- Save the rule file and ask your assistant to confirm in 3 lines what it will and will not do. Fix any misunderstanding now.
- Run it by hand three times and compare the result to what you would have done.
- Edit the rule file where it got things wrong.
- Only then put it on a schedule, for example weekdays at 8:30.
