For many executives the inbox is the to-do list, the filing system and the source of most interruptions. Handing it to an assistant can give back hours a week — but only with a clear system. Here's one that works, adaptable for Gmail or Outlook.
The goal
Define success in one sentence, for example: "At the end of each day, fewer than 20 messages need my attention, and everything important has been answered or is on my list."
The folder or label system
Keep it simple. Five folders cover most needs:
| Folder | What goes there | Who acts |
|---|---|---|
| 1-Action-You | Needs your decision or personal reply | You |
| 2-Review | Drafts prepared by your assistant for approval | You |
| 3-Waiting | Awaiting someone else's response | Assistant tracks |
| 4-Read | FYI, newsletters you want, reports | You, when you choose |
| Archive | Done or no action needed | — |
Your assistant moves every new message into one of these during triage.
Triage rules
Write rules your assistant can apply consistently:
Always flag for you
- Board members, investors, your manager
- Top customers and partners (keep a VIP list)
- Legal, HR or financial matters
- Anything mentioning a deadline in the next 48 hours
Assistant handles directly
- Scheduling requests (using your calendar rules)
- Routine vendor and admin correspondence
- Confirmations, receipts and notifications
- Unsubscribing from unwanted newsletters
Assistant drafts for review
- Replies to routine requests where your voice matters
- Introductions and follow-ups after meetings
- Polite declines
Delegation access: start with drafts
Both Google Workspace and Microsoft 365 support delegate access. Start with permissions to read, organize and draft. After a few weeks, if you're comfortable, grant send-as or send-on-behalf for defined categories — scheduling, confirmations, introductions.
Security basics apply: a named delegate account, MFA and clear rules about what may be forwarded. See the remote assistant security checklist.
Writing in your voice
Give your assistant five to ten examples of emails you've written — short replies, declines, introductions. Ask them to build a style sheet:
- Greeting and sign-off
- Typical length
- Level of formality
- Phrases you use (and ones you never use)
Review drafts closely in the first two weeks, then spot-check.
The daily rhythm
- Morning triage before your day starts: everything sorted, urgent items flagged at the top.
- Midday sweep: new messages sorted; quick items handled.
- End-of-day summary: what's waiting for you, what's been handled, what's pending with others.
You check 1-Action-You and 2-Review at set times rather than all day.
Handling sensitive email
Agree in advance what's off-limits or must be left unread, such as personal matters, HR investigations or board-confidential threads. Use filters to route those directly to a folder your assistant doesn't process, or use a separate account.
Tracking follow-ups
The 3-Waiting folder is only useful if someone checks it. Your assistant reviews it daily and nudges where responses are overdue, using templates you approve.
Phishing awareness
Executives are frequent targets of impersonation and payment-redirection scams. Your assistant should:
- Verify any unusual payment or data request through a known channel
- Never click links or open attachments from unexpected senders without checking
- Report suspicious emails to your IT contact
The FBI's Internet Crime Complaint Center is where business email compromise incidents can be reported.
Common mistakes
- Too many folders. Five is plenty.
- No VIP list. Your assistant can't guess who matters most.
- Granting send-as on day one. Build trust with drafts first.
- Checking everything anyway. Trust the system; check the folders at set times.
A worked example: from 180 emails a day to a 15-minute review
Here's an illustrative inbox for a CEO receiving about 180 emails a day. With an assistant triaging, the CEO's daily involvement drops to two short review sessions.
| Category | Share of volume (illustrative) | Assistant action |
|---|---|---|
| Newsletters, notifications, receipts | ~45% | Auto-filtered by rules; receipts forwarded to bookkeeping |
| Scheduling requests | ~15% | Handled directly under calendar rules |
| Vendor and sales pitches | ~10% | Polite decline template, or forwarded to the right team |
| Internal FYI and cc's | ~15% | Summarized in the daily brief |
| Needs the CEO's reply | ~10% | Drafted for approval, or flagged with context |
| Truly urgent | under 5% | Sent to the CEO immediately by text or Slack |
The CEO reviews the "Needs reply" folder twice a day and sends approved drafts. The rest never needs their attention.
Folder or label structure
Keep it short. More folders mean more decisions:
- 1-Action (needs the executive)
- 2-Waiting (sent, awaiting reply; follow-up dates tracked)
- 3-Read (FYI, summarized in the daily brief)
- 4-Done (archived)
- Receipts (auto-forwarded to finance)
Numbering keeps the important folders at the top in Gmail and Outlook.
The daily brief template
The assistant sends this once or twice a day:
- Urgent (handled or flagged): one line each
- Needs your reply: item, sender, one-line context, suggested response
- Decisions waiting: what's blocked until you answer
- FYI summary: five bullets maximum
- Follow-ups due today: people you're waiting on
Delegation permissions, step by step
| Stage | Permission | When to move on |
|---|---|---|
| Weeks 1–2 | Read and organize; draft only | When drafts need few edits |
| Weeks 3–6 | Send scheduling and routine replies from the executive's account or as "on behalf of" | After two weeks with no corrections |
| Month 2+ | Send approved categories of replies in the executive's voice | Review a sample weekly |
Gmail's mail delegation and Outlook's delegate access both let an assistant work in your mailbox under their own credentials, without your password. Use those features instead of sharing a login.
Rules for sensitive email
- Legal, HR, board, M&A and personal health or family topics go to a restricted folder that the assistant doesn't open, if that's the executive's preference. Agree this explicitly.
- Never forward sensitive content to personal email or external tools.
- Payment or banking requests, even from known senders, are verified by phone using a known number before any action. Business email compromise often impersonates executives and vendors.
Weekly inbox metrics
- Emails in "1-Action" older than 48 hours
- Items in "2-Waiting" past their follow-up date
- Median time to reply for external emails that need a response
- Number of urgent escalations, and whether each was truly urgent
Revisit the filters and folders every quarter. New tools and new roles change what arrives, and stale rules quietly bury important mail.
The bottom line
Inbox management is delegable when it runs on a simple folder system, written triage rules, staged access and a daily rhythm. Most executives who set this up find they spend far less time in email — and miss fewer important messages.
