What needs you today, this week, or not at all — sorted by what happens if you ignore it, not by when it arrived.
Email agents

Your agent, on Email
AI agents for email
Email is where work goes to wait. Your agent gets its own mailbox: it triages what arrives, answers the routine threads in your voice, drafts the ones that need you, chases the replies nobody chased, and sends one digest instead of four hundred unread.
TL;DR
What it handles
01
What needs you today, this week, or not at all — sorted by what happens if you ignore it, not by when it arrived.
02
Pricing, availability, where to send the invoice, the attachment they lost — answered in your voice from your own information.
03
Quote, thread history and what you said last time are assembled, so you edit instead of composing.
04
The thread that went quiet eleven days ago gets one polite nudge, and the reply lands back in the same thread.
05
“Any time Tuesday?” becomes a proposed time, an invite and a reply, instead of six messages narrowing it down.
06
Anything committing money, dates or promises you did not authorise stops as a draft rather than being sent.
A real thread
The sender gets a real answer to the actual question, in your voice, with you on the thread. Nothing announces that a machine handled it, because nothing about the answer needs an excuse.
An email agent vs inbox rules and templates
Rules, labels and canned responses sort your inbox into piles you still have to work through. The unread count goes down; the amount of writing you owe people does not.
| Capability | Your Email agent | Filters, labels and templates |
|---|---|---|
| What it does with a message | Answers it, or drafts the answer. | Puts it in a folder. |
| Routine questions | Handled end to end, in your voice. | A template you still have to pick and edit. |
| Follow-ups | Chased on its own, once, in the same thread. | A reminder you snooze. |
| Attachments | Read, with the missing piece named. | Downloaded, by you. |
| Scheduling | Proposes, invites, confirms. | Six emails and a calendar link. |
| Your morning | One digest of what matters. | Four hundred unread, neatly labelled. |

The assistant that never sleeps: email intelligence, calendar, reminders, a daily digest, and a browser handoff when the answer is behind a login.
What comes with it
Evidence
Published research on email load and AI-assisted writing. None of these studies tested Keiki — they measure the behaviour an email agent is built on.
Time in the inbox tracks stress and fragmented attention.
A study of information workers logging email activity found that longer time spent in email was associated with higher stress and more self-interruption.

Drafting with AI is faster and rated better.
In a preregistered experiment with 453 professionals, ChatGPT cut the time spent on mid-level writing tasks and raised output quality as judged by blinded evaluators.

Replying quickly is what keeps an enquiry alive.
A study of how firms handle online enquiries found most reply far too slowly to reach a prospect while the enquiry is still live.
