How to Build a Claude Skill That Handles Your Email Triage

The average knowledge worker spends about 28% of their workday on email. That's roughly two hours and fifteen minutes of every eight-hour day reading, sorting, drafting, and re-reading things they already read. If that number doesn't make you want to throw your laptop into the ocean, you've either made peace with it or you stopped feeling it years ago.

Either way, there's a better approach. A Claude-based email triage skill won't zero out your inbox time, but it can dramatically reduce the cognitive cost of processing it.

The triage problem

Triage has three steps: categorize, prioritize, and respond. Most people do all three in parallel, which is why inbox time feels exhausting. You're reading a message while simultaneously deciding what it is, how urgent it is, and what you need to say back. That context-switching is expensive.

A good triage skill separates those steps. You paste a batch of emails in, and it gives you a structured breakdown before you make a single decision. Then you can actually think.

The skill structure

Here's what a solid email triage skill looks like under the hood:

You are an executive assistant helping triage an email inbox.

For each email provided, output the following structure:

FROM: [sender name and email]
SUBJECT: [subject line]
CATEGORY: [Action Required / FYI / Waiting For Reply / Scheduling / Junk]
PRIORITY: [High / Medium / Low]
SUMMARY: [one sentence: what does this person actually want?]
SUGGESTED RESPONSE: [2-3 sentences if action required; No reply needed otherwise]
DEADLINE: [date if mentioned or implied; None stated otherwise]

Prioritization rules:
- High: requires action today or has a deadline within 48 hours
- Medium: requires action this week
- Low: no time sensitivity or purely informational

For suggested responses, be direct and professional.
Match the formality level of the incoming email.

The categories are the key design decision here. Adapt them to your actual inbox patterns. If you get a lot of vendor pitches, add a Vendor Outreach category so you can batch-process them. If scheduling is a constant drain, treat it as its own category and handle it in one focused session.

The copy-paste workflow

This works best as a morning ritual. Select ten to twenty emails from your inbox, copy the sender, subject, and body for each, paste them into the skill, and review the structured output. The whole process takes about five minutes. What you get back is a prioritized action list, not a pile of messages.

The goal is not to automate email entirely. It's to separate the sorting from the deciding, so your attention goes to the things that actually need it.

For suggested responses, you still review and edit. The skill is giving you a starting draft and a frame, not a finished reply. Most of the time you'll adjust the tone or add context the skill didn't have. But starting from a draft is categorically faster than starting from a blank field.

Practical limits to know up front

A few things this skill genuinely cannot do well. It cannot know your relationship with the sender. An email from your biggest client reads the same as one from a stranger on paper, but you know the difference. The skill doesn't. Always override its priority rating if you have relational context it's missing.

It also cannot read between the lines on political emails, the kind where the real message is buried under three paragraphs of professional pleasantries. You'll know those when you see the suggested response and think "absolutely not." That's fine. The skill isn't trying to replace judgment. It's trying to reduce the volume of decisions so the ones that need judgment get your full attention.

Build it or buy it

If you want to build your own, start with the template above and iterate based on your actual inbox for two weeks. Pay attention to where the suggested responses miss the mark: those gaps will tell you exactly what to add to the prompt. If you'd rather start with something already tuned, browse the email and productivity skills on SkillsLib.ai. Several sellers have built triage skills for specific professional contexts: legal, sales, customer support. Starting from one of those will save you the iteration time.
