Email System Audit SKILL.md

The Email System Audit skill makes Claude, Codex or another AI agent find where your email time goes and fix the biggest leaks. It counts a typical week by source, measures checking habits, scores ten areas from triage to security, designs a simple email system with filters, response targets, templates and follow-up tracking, agrees team norms and rolls changes out over four weeks.

email-system-audit/SKILL.md, version 1.0.0, 1,499 words.

Email problems rarely come from one bad habit. They come from a system nobody designed: notifications on for everything, dozens of newsletters, folders nobody uses, colleagues copying everyone, no rule for response times and an inbox checked fifty times a day. Each part costs a few minutes; together they cost hours a week and much of the person's focus.

This skill audits how a person or small team uses email, measures where time goes, finds the few changes with the biggest effect and builds a simple email system: rules, filters, a triage rhythm, response targets, templates and team norms. It is the entry point for the Email and Inbox set.

Operating principles

  1. Measure before changing. Volume, sources and time spent show where the real problem sits.
  2. Fix the source, not the symptom. Unsubscribing and team norms beat faster reading.
  3. Few moving parts. A handful of categories, filters and routines the person will keep.
  4. Protect focus. Email should fit into set sessions, not interrupt every hour.
  5. Keep people informed. Clear response targets make batching safe.

When to use, and when not to

Use it when email takes too much of the day, the inbox feels out of control, a person starts a new role, a team wants better email habits, or before setting up an AI email assistant.

Don't use it to sort today's inbox (inbox-triage) or to write a specific reply (email-reply-drafting).

Inputs to ask for, in one message

  1. Role and the people the person most needs to hear from.
  2. Rough daily volume, or access to count a typical week.
  3. Current folders, labels and filters.
  4. Notification settings on desktop and phone.
  5. What feels most broken.
  6. For teams: how email, chat and meetings are used.

# Email System Audit

Email problems rarely come from one bad habit. They come from a system nobody designed: notifications on for everything, dozens of newsletters, folders nobody uses, colleagues copying everyone, no rule for response times and an inbox checked fifty times a day. Each part costs a few minutes; together they cost hours a week and much of the person's focus.

This skill audits how a person or small team uses email, measures where time goes, finds the few changes with the biggest effect and builds a simple email system: rules, filters, a triage rhythm, response targets, templates and team norms. It is the entry point for the Email and Inbox set.

## Operating principles
1. **Measure before changing.** Volume, sources and time spent show where the real problem sits.
2. **Fix the source, not the symptom.** Unsubscribing and team norms beat faster reading.
3. **Few moving parts.** A handful of categories, filters and routines the person will keep.
4. **Protect focus.** Email should fit into set sessions, not interrupt every hour.
5. **Keep people informed.** Clear response targets make batching safe.

## Audit areas
| Area | What to check | Typical finding |
|---|---|---|
| Volume and sources | Emails a day by type: people, notifications, newsletters, internal lists | Over half is automated or bulk mail |
| Checking habits | How often the inbox is opened; notifications on or off | Checked constantly; alerts for every message |
| Triage | How messages get decisions | Messages read several times before action |
| Structure | Folders, labels, filters | Many folders, few used; no filters |
| Response times | Expectations by sender type | No targets; anxiety about slow replies |
| Writing | Length and clarity of sent emails | Long emails, unclear asks |
| Follow-ups | How promises and waiting items are tracked | Relies on memory; things slip |
| Templates | Repeated replies | Same answers rewritten weekly |
| Team norms | Cc habits, reply-all, chat versus email | Everyone copied; urgent issues by email |
| Security | Phishing awareness, two-step login | Payment change requests not verified |

## When to use, and when not to
Use it when email takes too much of the day, the inbox feels out of control, a person starts a new role, a team wants better email habits, or before setting up an AI email assistant.

Don't use it to sort today's inbox (`inbox-triage`) or to write a specific reply (`email-reply-drafting`).

## Inputs to ask for, in one message
1. Role and the people the person most needs to hear from.
2. Rough daily volume, or access to count a typical week.
3. Current folders, labels and filters.
4. Notification settings on desktop and phone.
5. What feels most broken.
6. For teams: how email, chat and meetings are used.

## Workflow

### Step 1. Count a typical week
Group messages by source: named people, internal lists, notifications from tools, newsletters and promotions, external requests. Note which sources lead to action.

### Step 2. Estimate time
Time in the inbox per day, how many sessions, and time on replies versus reading.

### Step 3. Score each area
Score 0 to 3 with one line of evidence each.

### Step 4. Find the top leaks
Usually: too much bulk mail, constant checking, no follow-up tracking, or team habits that create mail.

### Step 5. Design the system
- Triage two to four times a day with the six triage categories.
- Filters that move bulk mail and notifications out of the main inbox.
- Response targets by sender type.
- A waiting-for list for follow-ups.
- Templates for the five most repeated replies.
- Notifications off except for priority senders.

### Step 6. Agree team norms (if relevant)
When to use email versus chat versus a call, Cc and reply-all rules, subject line conventions, and the route for urgent issues.

### Step 7. Roll out gradually
Week one: filters and unsubscribing. Week two: triage rhythm and notifications. Week three: templates and follow-up tracking. Week four: team norms.

### Step 8. Measure again
After a month, compare volume, time in the inbox and missed follow-ups.

## Scorecard template
```
| Area | Score (0-3) | Evidence | Fix | Skill |
| Volume | 1 | 62% bulk mail | Unsubscribe and filter | newsletter-cleanup, inbox-rules-filters |
| Follow-ups | 0 | Two missed client replies | Waiting-for list | follow-up-tracking |
```

## Response targets example
| Sender | Target |
|---|---|
| Key clients and manager | Same working day |
| Team | Within 24 hours |
| External requests | Within 3 working days |
| Newsletters and notifications | No reply needed |

## Team email norms example
- Email for decisions and external contact; chat for quick questions; calls for anything urgent or sensitive.
- Cc only people who need to act or must know; say why in the first line.
- Reply-all only when everyone needs the answer.
- Subject lines start with the action and date when one is needed.
- No expectation of replies outside working hours.

## Measures to track
| Measure | Why |
|---|---|
| Emails a day reaching the main inbox | Volume after filters |
| Inbox sessions a day and minutes per session | Checking habits |
| Median reply time to priority senders | Responsiveness |
| Missed follow-ups a month | Reliability |
| Bulk senders unsubscribed | Source reduction |
Record a baseline before changes and compare after four weeks.

## Quick wins in the first hour
Turn off new-mail notifications, unsubscribe from the ten noisiest senders, create one filter for tool notifications, and book three daily triage slots in the calendar.

## Edge cases and judgement calls
| Situation | What to do |
|---|---|
| Role is mostly email (support, sales) | Shorter triage cycles; strong templates; shared inbox rules |
| Executive with assistant | Delegation rules and a daily brief |
| Heavy regulatory record-keeping | Keep archiving and retention rules; never auto-delete |
| Several accounts | One triage session covering all, or forwarding to one inbox |
| Team resists norms | Trial for four weeks and review the results together |

## Handoffs to specialist skills
- Daily sorting: `inbox-triage`
- Replies: `email-reply-drafting`
- Follow-ups: `follow-up-tracking`
- Filters: `inbox-rules-filters`
- Subscriptions: `newsletter-cleanup`
- Repeated replies: `email-templates`
- Hard messages: `difficult-emails`
- Clearer emails: `email-writing-clarity`
- Phishing and fraud: `email-security`

## Worked example
A sales manager received about 180 emails a day and spent close to three hours in the inbox. The audit found 58% bulk and tool notifications, the inbox open almost all day, no filters and two missed client follow-ups in a month. The plan unsubscribed from 40 senders, filtered tool notifications into a weekly digest folder, set three triage sessions, turned off notifications except for key clients, added a waiting-for list and five reply templates, and agreed Cc rules with the team. A month later, daily volume in the main inbox had fallen by more than half, inbox time was about an hour, and no client follow-ups were missed.

## Output format
```
# Email audit: <person or team>, <date>
## Summary (top leaks and first moves)
## Volume and sources
## Time and checking habits
## Scorecard
## Email system (triage rhythm, filters, targets, templates, follow-ups)
## Team norms (if relevant)
## Four-week rollout
## Measures to check after a month
```

## Common mistakes
- Reading faster instead of reducing volume.
- Folders for everything.
- Notifications on for all mail.
- No response targets, so batching feels risky.
- Ignoring team habits that create mail.

## Self-check before you answer
- Is volume measured by source?
- Are the top two or three leaks fixed first?
- Is the system simple enough to keep?
- Is there a measure to check after a month?

  • Is volume measured by source?

When to use this skill, and when not to

Use it when email takes over your day, your inbox feels out of control, you start a new role, your team wants better habits or before setting up an AI email assistant.

Email problems come from a system nobody designed: notifications for everything, dozens of newsletters, unused folders, everyone copied and the inbox checked constantly. Each costs minutes; together they cost hours.

Don’t use it to sort today's inbox; use Inbox Triage.

Example prompts

  • “Audit my email habits and tell me what to fix first.”
  • “Where does my email time go?”
  • “Set email norms for my team.”
  • “Prepare my inbox before I connect an AI assistant.”
  • “Measure my email before and after changes.”

Example output

The skill returns a fixed structure. A shortened example for an imaginary site:

Volume: 180 a day, 58% bulk and tool notifications
Time: about 3 hours a day; inbox open all day
Leaks: no filters, constant checking, 2 missed client follow-ups
System: 40 unsubscribes, notification filter, 3 triage sessions, VIP alerts only, waiting-for list, 5 templates, Cc rules
After a month: main inbox down by half, about 1 hour a day

Volume is measured by source before anything changes, so fixes target the real cause rather than reading faster.

What the agent needs from you

The skill asks for your role and priority senders, rough daily volume or access to count a week, current folders and filters, notification settings, what feels most broken and, for teams, how email, chat and meetings are used.

How to run Email System Audit step by step

  1. Install the skill as email-system-audit/SKILL.md.
  2. Count a typical week by source.
  3. Score the ten areas.
  4. Pick the top two or three leaks.
  5. Roll out changes one week at a time.
  6. Measure again after four weeks.

Situations this skill handles

Email setups differ. The skill handles these:

SituationWhat the skill does
Support or sales roleShorter cycles, strong templates
Executive with assistantDelegation rules and daily brief
Record-keeping rulesArchive, never auto-delete
Several accountsOne triage covering all
Team resists normsFour-week trial and review
AI assistant plannedFilters and rules first

What makes this skill different

Most email advice is about answering faster. This audit measures where mail comes from and removes it at the source, then builds a small system of filters, targets, templates and follow-up tracking you will actually keep.

It includes team norms, because colleagues often create much of the volume.

Practical tips from real projects

  • Measure before changing.
  • Fix the source.
  • Few moving parts.
  • Protect focus.

A worked example: a sales manager received about 180 emails a day and spent close to three hours in the inbox. The audit found 58% bulk and tool notifications, the inbox open almost all day, no filters and two missed client follow-ups in a month. The plan unsubscribed from 40 senders, filtered tool notifications into a weekly digest folder, set three triage sessions, turned off notifications except for key clients, added a waiting-for list and five reply templates and agreed Cc rules with the team. A month later the main inbox had fallen by more than half and inbox time was about an hour a day.

The audit scores ten areas from 0 to 3: volume and sources, checking habits, triage, structure, response times, writing, follow-ups, templates, team norms and security. Typical findings include more than half of mail being automated, constant checking with alerts for every message, messages read several times before action, many unused folders, no response targets, long emails with unclear asks, promises tracked by memory, the same answers rewritten weekly, everyone copied by default and payment change requests not verified.

The resulting system is small: two to four triage sessions a day, filters that move bulk mail out of the main inbox, response targets by sender type, a waiting-for list, templates for the five most repeated replies and notifications only for priority senders. Example targets are same working day for key clients and the manager, 24 hours for the team, three working days for external requests and no reply for newsletters.

Team norms keep email for decisions and external contact, chat for quick questions and calls for urgent or sensitive matters, ask people to Cc only those who must act or know, reserve reply-all for when everyone needs the answer, start subject lines with the action and date and remove any expectation of replies outside working hours.

The rollout spreads change over four weeks: filters and unsubscribing first, then the triage rhythm and notifications, then templates and follow-up tracking, then team norms. Quick wins in the first hour are turning off new-mail notifications, unsubscribing from the ten noisiest senders, creating one filter for tool notifications and booking three daily triage slots.

Measures recorded before and after include emails a day reaching the main inbox, sessions and minutes a day, median reply time to priority senders, missed follow-ups a month and bulk senders removed.

Some roles need adjustments. Support and sales roles that live in email use shorter triage cycles and strong templates. Executives with assistants get delegation rules and a daily brief. Teams with record-keeping duties archive and label but never delete automatically. People with several accounts run one triage session covering all of them or forward everything to one inbox, and teams that resist new norms try them for four weeks and then review the results together.

The first hour usually delivers the most visible change, because turning off notifications and filtering tool mail removes dozens of interruptions immediately.

Frequently asked questions

Volume by source, checking habits, triage, structure, response targets, writing, follow-ups, templates, team norms and security.

Unsubscribe from unread senders, filter tool notifications, switch tools to digests and agree team Cc rules.

Two to four batched sessions a day with response targets work for most roles.

Agreed reply times by sender type, such as same day for key clients and three working days for external requests.

Email for decisions and external contact, chat for quick questions, calls for urgent issues, careful Cc and reply-all.

Compare main-inbox volume, inbox time, reply times and missed follow-ups after four weeks.
