Email triage is the sorting that happens before any reply: what needs a person now, what can wait, and who should handle it. AI email triage does that sorting for every incoming thread. It scores priority, tags the intent and assigns an owner by rule, so the inbox is already in order when the team opens it in Gmail or Outlook.
This explainer covers what triage is, what the AI version does and does not do, how to evaluate a tool, and which shared inbox products ship it. We build Sektra, which ships priority scoring and intent tagging, so this is a Product post and our own section is the fullest. The table of other tools is neutral and checked against each vendor's site in October 2026.
AI email triage reads each incoming thread and attaches three things: a priority, an intent tag and an owner. It does not send anything. Evaluate a tool on whether it explains the score and whether it works on Gmail and Outlook, shared mailboxes included. Then ask what happens when it is wrong, and whether triage runs on every thread at no extra charge.
What is AI email triage?
Triage is a word borrowed from medicine, where it means sorting patients by urgency before treating anyone. In email it means the same sorting before anyone replies. A person does it by reading everything in arrival order. Filters do a crude version by sender and subject line. AI triage reads the content and the context and produces a judgment for each thread.
The output is three fields on the thread. A priority, which is a ranking of what it would cost to leave the thread unanswered. An intent tag, which is what the sender wants. And an owner, which a rule assigns using the first two. Everything else the AI might do, such as summaries or draft replies, is adjacent to triage and should be judged separately.
What AI email triage does
Priority scoring
A score ranks threads by consequence instead of by arrival time. The inputs that matter are who is waiting on whom, deadline language in the message, how long the thread has been open, and who the sender is to your business. A good score comes with its reason attached, so the person reading it can agree or disagree in a second.
Intent tags
An intent tag says what the sender wants: a contract to sign, an approval, a renewal, a payment, a complaint, a meeting. Tags make the inbox filterable by what the mail is about instead of by who sent it, and they are the input that assignment rules use.
Assignment by rule
The AI supplies the tag; the rule supplies the owner. Payments to finance, renewals to the account owner, everything else round robin or to whoever has the least on their plate. The rule is written by the team and runs the same way every time. Nobody has to work out who should take a thread before anyone can start on it.
What AI email triage should not do
It should not send anything on its own. Triage is advisory. A wrong score costs a few minutes; a wrong reply sent to a client in your name cannot be recalled. Tools that answer inbound without a person are AI agents or deflection products, a different category with a different risk. AI deflection vs relationship memory covers them.
It should not hide mail. A low score is still visible in the list, below the high ones. And it should not need weeks of hand training per tag before it works. Front's legacy AI Tagging asked admins to approve ten messages per tag before automatic tagging began. Its help center now marks that feature as no longer available to new users. Tagging that works on day one is the standard.
How to evaluate an AI email triage tool
- Does it explain the score? A priority with no reason gets ignored within a week.
- Does it run on Gmail and Outlook, including Microsoft 365 shared mailboxes, with the same features on both?
- What happens when it is wrong? You should be able to change the priority or tag on the thread in one click, and a rule should be able to override the model for a named sender.
- Does the tag drive a rule? Tagging without assignment leaves the sorting half done.
- Does triage run on every thread, or is it metered? A per-thread or per-resolution charge changes how a team uses it.
- How does the tool reach the mailbox? For Gmail and Outlook, through Google or Microsoft sign-in, with no password handed to the vendor.
- What does it remember past today? A score sorts the morning. A record of what each client was promised and what they are still waiting on is what the afternoon needs.
Which shared inbox tools ship AI email triage?
Five shared inbox products name triage features on their own sites. The table lists what each site says, in its own terms, and whether the AI sends anything by itself. Prices and tiers are left out because they change; each vendor's pricing page has them.
| Tool | Where it runs | Triage features named on its site | Sends on its own |
|---|---|---|---|
| Front | Its own app | Topics, which reveal patterns behind conversations, under analytics; intelligent routing, named in its FAQ without detail. Autopilot is an AI agent sold as a separate add-on, and Copilot suggested replies are also an add-on below Enterprise. AI Tagging is marked legacy. | Autopilot resolves inquiries on its own |
| Missive | Its own app | AI rules that analyze emails and perform actions; auto-assignment to a coworker; workload balancing by round-robin, least busy first, all at once or randomly. Each rule needs configuring. | No. Drafts wait for approval |
| Hiver | A Chrome extension in the Gmail interface; a browser app its site says is under development | Automation rules for routing, triage and SLA alerts, built for support queues; sentiment under Customer Intelligence; AI Copilot drafts; AI Agents that can be assigned tasks. | AI Agents act on assigned tasks |
| Gmelius | A Gmail-native platform; its site does not mention Outlook | AI Agents that read and triage a shared inbox, and Meli, an AI chief of staff described as the intelligence layer behind them. Its site names no priority score or intent tag. | Agents act across connected tools |
| Sektra | A separate workspace synced two-way with Gmail, Outlook, IMAP and WhatsApp Business | Priority scoring with the reason shown, intent tags, assignment round robin or to the least loaded teammate, on every thread at no extra charge. Underneath, a record per client of what was promised. | No. Drafts and actions wait for confirmation |
Two patterns in the table. The tools that run in the Gmail interface triage only there, so an Outlook shared mailbox sits outside them. And the products whose AI acts on its own put the sending question on the buyer: every agent needs a boundary written for it. Sektra draws that boundary once, in the product. The comparison pages set each of these tools beside it in full.
How Sektra triages an inbox
Every thread that arrives in a connected Gmail, Outlook, IMAP or WhatsApp Business mailbox is scored by what it would cost to ignore, and the score shows its reason. Sektra knows whether you owe the reply or you are waiting on them, and ranks accordingly. On Outlook, Microsoft's Focused and Other classification is one input to the score, so promotional mail stays low.
The same pass tags each thread by intent. Contracts, approvals, renewals and payments are labeled as they arrive, and the inbox filters itself by them. Assignment rules then route by tag, round robin, or to whoever has the least open. Triage runs on every thread as part of the plan, with no meter on it.
Nothing is sent by the AI. The assistant is what we call Sektra's AI. It drafts replies and answers questions about a client with links to the threads the answer came from. It acts on the inbox with confirmation: assign, tag, snooze, archive, add a note. Those requests use credits, the unit the plan meters, and triage does not.
Under the triage sits the memory layer, a record per client of what was promised in either direction with dates. It also holds what they asked that has no answer yet, and who is involved. Lens, the panel beside every thread, shows it. Action items, the list of reminders, watches and jobs, includes a silence watch that tells you the day an account goes quiet past a day count you set. The morning digest lists what you owe and who owes you.
That is the part of triage that outlasts the morning, and the reason an account management team on Outlook or Gmail chooses it. The Outlook integration page covers shared mailboxes and categories, and the product page has the rest.
