AI agents for Gmail inbox triage

Busy executives, ops leads, and account managers spend hours each day on email — reading, prioritising, deciding what needs a response, and drafting replies. AI agents connected to Gmail handles the triage layer: it reads the inbox, surfaces what matters, extracts action items, and drafts responses for review. The human reads less and responds faster.

The inbox management problem

A full inbox contains a mix of things that don't look the same from the subject line:

• Emails that need a response today
• Emails that need a response eventually
• Emails that contain an action item for someone else
• Emails that are informational and need no response
• Emails that are noise and should be archived

Most people process all of these the same way — they open each one, read it, decide what to do, and move on. For 100+ emails a day, that's a significant drain on attention.

What AI agents handle

An Envelope team connected to Gmail reads your inbox on a schedule, classifies each unread email, surfaces the ones that need your attention today, extracts action items, and drafts replies for your review.

The agents

Email Reader fetches unread emails from the inbox (or a specific label) in the defined window — last 24 hours is the most common interval. It reads the full content of each message and any relevant thread history.

Priority Sorter classifies each email into one of four categories: respond today (time-sensitive, sender is a key contact, or contains a question requiring your answer), respond this week (not urgent but needs a reply), action item for someone else (you need to delegate or forward), or archive (informational or no action required). Priority signals include sender importance, keywords, time references, and whether you're in the To or CC field.

Action Item Extractor reads the emails tagged "respond today" and "action item for someone else" and extracts the specific asks: what do they need, by when, and from whom. It formats these as a clean action list.

Response Drafter writes draft replies for each email in the "respond today" category. The draft matches your communication style, addresses the specific question, and is ready to send with light editing. Drafts are saved to Gmail as drafts, not sent automatically.

Setting this up in Envelope

1. Describe the team: "Each morning, read my Gmail inbox from the last 24 hours, surface emails that need a response today, extract any action items, and draft replies for my review."
2. Connect your Gmail account under Tools — the team needs read access for triage and draft access for responses.
3. Define your priority signals: which senders are always high priority, which domains to deprioritise, which keywords indicate urgency.
4. Set your communication style: formal or informal, how long your replies typically are, any phrases or sign-offs you use.
5. Set the schedule: most people run this once in the morning, some run it after lunch too.
6. Review the output in the Envelope workspace before going to your inbox.

What you see each morning

The team delivers a structured digest:

Respond today (3 emails)

• Sarah Chen, re: Q3 budget sign-off — needs approval by Friday, draft saved
• James from Acme Corp, re: contract renewal — asks about pricing for 50 seats, draft saved
• Legal, re: NDA for supplier — awaiting your signature, action: check DocuSign

Action items for others (2)

• Forward Marcus's question about the API docs to the engineering team
• Schedule follow-up with Priya per her request — delegate to EA

Archived (14 emails)

• 8 newsletters, 3 automated receipts, 3 informational updates

You open Gmail with three things to respond to and a clear action list. The rest is handled.

Variations worth building

VIP sender routing — emails from a defined list of key contacts bypass the queue and trigger an immediate notification regardless of the schedule.

Thread summariser — for long email threads you've been CC'd on, the team reads the full thread and posts a two-sentence "what you need to know" summary rather than asking you to read 40 messages.

Weekly communication review — every Friday, the team reviews the week's sent emails and identifies any threads that have gone unanswered for more than 5 days, and any follow-ups you promised that haven't been sent yet.
