Free Missive Alternatives for a Shared Inbox (2026)

Missive charges per seat on every paid tier, and "free shared inbox" is one of the most searched escape hatches for small teams who like the product but cannot yet justify the monthly line item. Real free alternatives exist — but almost none are free in the way Missive's paid tiers are polished. They are free the way Google Calendar's shared calendars are free: functional, sometimes rough, extracting a cost you did not notice at signup.

This page walks through eight of them — starting with Missive's own free plan (the sensible first move is usually not to leave at all), through the Google Workspace and Microsoft 365 options most teams pay for and forget, and the Gmail-extension tiers of Hiver and Drag, ending with two self-hosted open-source inboxes that cost nothing per user forever on a VPS. Every capability claim was checked against vendor's own live pages in the last week of the update month.

The short answer: which free Missive alternative fits which team#

There is no single winner, because "a free shared inbox" describes at least four different problems. For a team of two or three, Missive's own free plan is the honest first pick — you get the collaboration Missive is known for and a small history window, without leaving the tool that already fits.

For a team already inside Google Workspace or Microsoft 365, the free shared inbox you have already paid for is your admin console, not a new SaaS. Google Groups Collaborative Inbox turns a group address into an assignable queue at no extra cost, and a Microsoft 365 shared mailbox does the same shape without eating a mailbox licence. Neither is a beautiful product — both are the truest form of "free" on this list.

For a small team that lives in Gmail and wants a shared-inbox layer without leaving Gmail's UI, Hiver's Free tier or Drag's Free tier each cover the basics — assign, note, status — for a handful of users. For teams comfortable running a container on a VPS, Freescout (help-desk-style) and Chatwoot (omnichannel) both self-host to zero recurring cost.

We build AI Emaily. We are not entry #1 here — AI Emaily has no permanent free plan (7-day trial on Pro or Autopilot, card required, cancel by day 7 for $0), and the product is an AI agent for the individual mailbox, not a shared team queue. Where we fit is stated further down.

How we compared#

This is a documented capability comparison as of August 2026, not a lab test — we did not spin up eight shared inboxes with fake teammates. Every capability claim was checked against vendor's live pricing or docs pages in the last week of the update month; where a vendor does not publish an answer we say so rather than fill it in.

The comparison axes are the ones that decide the switch for a budget-constrained team, not the generic feature list most roundups reprint from a marketing page:

• What free actually means for that option — free plan capped by users or history, free with a Workspace/365 licence you already pay for, free tier inside a paid tool, or open-source self-hosted.
• Where the shared inbox lives — a Gmail extension over your existing mailbox, a Google Group, a Microsoft 365 shared mailbox, a standalone web app, or a Docker container on your own server.
• Assignment and accountability — can a teammate claim a thread, hand it off, and see who owns what, or does the tool leave that to whoever answered last.
• Collision detection — does the tool warn a second person before they start typing on a thread someone else is already replying to.
• Real history — how many days or months of past conversation the free option keeps, because a shared inbox with no memory is a group chat you cannot search.
• The upgrade cliff — what a paid step up gets you, so you can tell whether "free" is an on-ramp or a wall.

Free Missive alternatives for a shared inbox: comparison table#

The "What free means" column matters more than the feature columns. Sort your options by what kind of free you actually have access to — free-with-Workspace, self-hostable, or capped-free-plan — before comparing the finer details.

1. Missive Free — the honest first stop for teams of three or fewer#

Before anything else, check whether Missive's free plan fits — it usually does for the smallest teams. The free tier seats a handful of users on one shared account with a short history window: enough for two or three co-founders, an ops-and-support pair, or a one-inbox agency team to run their shared address at no cost.

You get what Missive is known for: real-time collaborative drafting with live cursors, in-thread comments and mentions, two-way sync so the underlying Gmail, Google Workspace or IMAP mailbox stays checkable in its native client, and channels beyond email. Assignment is present, collision is baked into the co-editing model, and the mobile and desktop apps are the same ones paid users get.

Where it bends: history window is short, integrations and rules are capped, seat count is modest. Missive is deliberately quiet about the free plan on its pricing page — the sign-up flow surfaces it — so "can we stay free" is a question the plan answers but marketing does not advertise.

For a team of two or three who already like Missive's collaboration model, no free tool on this list beats staying put. It is the only option here that does not degrade the collaboration experience — it just trims history and seats. Only leave when a hard limit bites.

2. Google Groups Collaborative Inbox — free if you already run Google Workspace#

If your team is already on Google Workspace, the cheapest shared inbox is the one you have already paid for. Configure a Google Group as a Collaborative Inbox in the Admin console (Group → Information → General Information → Enable additional Google Groups features). That flips a distribution list into a shared queue where any member can take a conversation, mark it as "No action needed", "Complete" or "Duplicate", and assign it to another member.

It is free with any Workspace subscription, works with an existing team@ or support@ address, keeps mail in Google's infrastructure, and requires no third-party OAuth, no extension, and no software to install. For a team that just needs to know who is handling what on a low-volume address, it is the truest free on this page.

Where it falls short: the UI looks exactly like Google Groups. No live collision detection, no draft-editing collaboration, no useful keyboard shortcuts, and no analytics beyond message counts. If your reason to look at Missive was polish, Collaborative Inbox will feel like 2012 the moment you open it. Pick it when the free-inside-Google trade is worth the interface — usually it is for internal ops queues and low-volume inboxes.

3. Microsoft 365 shared mailbox — Outlook's built-in equivalent#

Microsoft 365 has a comparable feature most admins forget. A shared mailbox in Exchange Online is a real mailbox with its own address (support@, hello@), owned by the tenant rather than a person, that any assigned user can open in Outlook, Outlook on the web, or New Outlook for Mac. It does not consume an M365 licence up to 50 GB (100 GB if a licensed user assigns their licence to it) — free because you already pay for the plan.

In the M365 admin center, create a shared mailbox, add members, and each member sees it as an additional folder in Outlook. Replies come from the shared address, and sent copies land in the shared Sent Items folder when the tenant is configured to log them.

The catch: Outlook's shared mailbox is a mailbox, not a shared inbox in the Missive sense. No built-in assignment, no collision detection beyond "another person is drafting" hints, no thread ownership, no status like "Complete" — replies just move things to sent. Two people replying simultaneously is a live risk. If your team coordinates informally (a Slack ping before claiming a thread), it works; if not, you need a helpdesk on top and the free ends there.

4. Hiver Free — the Gmail extension option, capped#

Hiver's Free tier suits a team already living in Gmail that wants a shared-inbox layer without leaving Gmail's UI. It is a Chrome extension that presents team@ or support@ as an assignable queue with basic statuses and shared notes — inside Gmail, so no one learns a new tool.

The free tier covers the shared-inbox essentials: assign a conversation, add a private note, set a status (Open / Pending / Closed), and see what teammates are working on. It does not disturb Google's filters, labels, or Vacation Responder.

The limits are what any commercial free tier has. Hiver's paid tiers are Growth, Pro and Elite (verified July 2026); real collision detection, more rules, analytics, live-chat channels, SLA tracking, and more users all sit above the free line. Hiver's Free is a genuine on-ramp: start free and upgrade when you hit a wall. Pick it if Gmail is home and you want the shared-inbox layer without moving providers.

5. Drag Free — Gmail as Kanban boards for a small team#

Drag turns the Gmail inbox into Trello-style Kanban boards, and its Free tier suits teams whose brains work in columns and cards rather than folders and labels. Like Hiver, it is a Chrome extension — no server or migration needed.

In shared-inbox mode, each incoming message becomes a card — assigned, moved between columns (To do / Doing / Done), commented on, given due dates. For a team that has been faking a shared inbox by CC-ing each other on every reply, the mental model change is real: the queue becomes a visible board instead of a personal inbox everyone is pretending is a group's.

The Free tier caps shared boards, teammates, and automations. Drag's paid tiers are Starter, Plus and Pro — verify the current ceilings on dragapp.com, as they have moved before. Pick Drag over Hiver when the mental model is "our inbox is really a task board"; pick Hiver when it is "our inbox is an inbox, we just need to see who owns what".

6. Freescout — self-hosted, help-desk-shaped, free forever#

Freescout is an open-source, self-hosted shared inbox modelled on Help Scout — the pick for a team with a spare VPS that does not want to pay per seat forever. It is a PHP app on a LAMP-style stack with cron access; a $6/month Hetzner or DigitalOcean droplet handles a small team's volume. Code is on GitHub under AGPL-3.0.

It covers the essentials: shared mailboxes via IMAP/SMTP or forwarding, assignment, private notes, statuses (active, pending, closed), tags, workflows, and per-user activity view. No seat cost, no message cap, no history window — the ceiling is your server.

The cost is setup and maintenance: backups, TLS renewals, SMTP relay deliverability, PHP upgrades, and the occasional breaking migration. Paid modules on the Freescout store — tags, workflows, SMS, apps — are one-time payments; total lifetime cost stays low and predictable. Pick Freescout when the team has a technical person willing to own a small server.

7. Chatwoot Community — open-source, omnichannel, Docker-friendly#

Chatwoot is the omnichannel cousin to Freescout: an open-source shared inbox covering email, website live chat, WhatsApp Business, Facebook Messenger, Instagram DMs, SMS via a Twilio-style relay, and API-driven custom channels. The Community Edition is MIT-licensed and free to self-host.

It gives you assignment to individuals and teams, private notes with mentions, typing indicators as a collision hint, canned responses, labels, and per-agent workload views. Deployment is a Docker Compose file or Helm chart; a modest server handles small-team volume easily.

Like Freescout, "free" here means self-hosted and self-operated. The Community Edition excludes Enterprise features — SSO/SAML, custom roles, audit logs — but upgrading to Chatwoot's paid tier is data-preserving, not a rip-and-replace. Pick Chatwoot when the shared inbox needs to cover chat and social as well as email — one queue for all channels is where it materially beats email-only free options.

8. Gmail delegation — the free DIY floor#

Gmail account delegation is not a shared inbox — it is dishonest to call it one — but it is free, built into every Gmail and Workspace account, and what a real number of two-person teams are using instead of any of the tools above. So it belongs here, as the bottom option.

In Gmail settings under Accounts and Import → Grant access to your account, one person can delegate their mailbox to up to 10 other Gmail addresses. The delegates open the mailbox from the account switcher and can read, reply and archive on the delegator's behalf. Replies are sent as the mailbox owner, with the delegate's name shown in the sent header.

Everything that makes a shared inbox a shared inbox is missing: no assignment, no collision detection (two delegates replying to the same thread simultaneously is common), no per-person view of what to handle. Read/unread state is shared, so one person marking a thread read hides it from the others. When the delegator leaves, the mailbox does not transfer. Pick delegation only when the team is two people who already coordinate constantly and the alternative is nothing.

Where AI Emaily fits on a page about free shared inboxes — and where it does not#

We build AI Emaily, so this section is a disclosure. On a page about free shared inboxes, we are not the top pick: AI Emaily has no permanent free tier (7-day trial on Pro or Autopilot, card required, cancel by day 7 for $0), and the product is an AI agent for the individual mailbox, not a shared team queue. Forcing our row to the top would be a category error any informed reader catches immediately.

Where we fit is adjacent. The most common story we hear from teams running Missive, Hiver, or a Google Group is not that the shared inbox is broken — it is that the founder or account manager whose personal mailbox sits next to the shared one is drowning. That is the mailbox AI Emaily is built for: triage across Gmail, Outlook, Microsoft 365 and any IMAP account (iCloud included via app-specific password), drafting from a user-set Personal Context brain and per-client profiles, Copilot mode requiring one-tap approval before anything sends, and an audit log. Keep whichever shared inbox fits your team's address; try AI Emaily's trial for the individual mailboxes it does not touch.

How to choose the right free option for your situation#

Find the one that sounds like your team and go set it up.

• You are already a Missive customer and just want to shrink the bill for a team of three or fewer: stay on Missive's own free plan.
• You are already on Google Workspace and your shared address is an internal ops or low-volume external queue: enable Collaborative Inbox on a Google Group.
• You are on Microsoft 365 and your team uses Outlook for everything already: create a shared mailbox in the M365 admin center.
• You live in Gmail and want an assign-and-note layer without leaving Gmail: install Hiver Free.
• You live in Gmail and your team thinks in tasks and columns instead of threads: install Drag Free.
• You want zero recurring cost forever and you can maintain a small VPS: self-host Freescout.
• You need email plus website chat plus WhatsApp in one queue and you can run Docker: self-host Chatwoot Community.
• You are two people and you both already work out of one Gmail account informally: turn on Gmail delegation and stop pretending it is more than that.

One scoping note. This is the best guide to free shared inboxes, not the guide to the best shared inbox. Free shared inboxes always cost accountability, deliverability quirks, or an evening of setup — fine when a paid seat is genuinely out of reach, a bad trade the day the shared inbox becomes the company's front door. When that day arrives, the honest move is a paid tier on Missive, Front, Help Scout, or whichever paid shared inbox fits your team. This page's job was to keep you free until then.
