Free Shared Inbox: Every Genuinely Free Option in 2026 (And Where Each Breaks)

Yes, you can run a shared inbox for free, and this guide covers every option that is genuinely free rather than a trial wearing the word: Google Groups Collaborative Inbox, Gmail delegation, Google's new native Workspace shared inbox, an Outlook or Microsoft 365 shared mailbox, and the real free tiers of a handful of tools. Each one works, each one breaks at a specific team size or workflow, and this guide gives you the setup steps and the honest breaking point for all of them, so you know exactly what free buys and when it stops being enough.

If you want the ground-level definition first, our guide to what a shared inbox is covers it; this page is the deep-dive on the free options specifically.

Free tier or free trial? Read this first

Most roundups of free shared inbox tools quietly count free trials as free. A trial is a countdown, not a plan. This guide draws the line hard: everything below is either genuinely free forever on some plan you may already pay for, like Google Workspace or Microsoft 365, or a real free tier with published limits. Where a tool only offers a trial, we say so, including our own: Drag is a paid tool with a 7-day trial and no free plan, and we would rather tell you that in the second paragraph than have you discover it at checkout.

What to look for in a free option

Two questions decide whether a free option fits. First, does it fit your team: most free options cap how many people or inboxes you get, which rarely matters for a handful of users but bites the moment you grow past it. Second, does it carry your workflow: an option that gives shared access but no assignment or collision detection works at low volume and strains as email climbs. Match those two against your real numbers before you commit, because the migration later is the expensive part.

Google Groups Collaborative Inbox

Free with Google Workspace, Collaborative Inbox turns a Google Group into a shared queue where members can take, assign, and mark conversations as resolved. It is the closest thing to a shared inbox that Google shipped before 2026, and for a small team on low volume it works. You enable it from the group's settings by turning on the additional Collaborative Inbox features. Our Gmail shared inbox guide walks the full Gmail-method setup.

Where it breaks

It lives in a separate, dated Groups interface, not inside Gmail, with no collision detection, no automation, and no analytics. The structural trap: if a member forgets to copy the Group address when replying, the thread goes dark for everyone else. Fine at dozens of emails a week, painful at hundreds. For the full setup, see our dedicated Google Groups Collaborative Inbox guide.

Gmail delegation

Gmail delegation is free on any Gmail account and takes one minute: Settings > Accounts and Import > Grant access to your account, then the delegate can read, send, and delete on your behalf from their own Gmail. It shares one person's mailbox with a team without shared passwords.

Where it breaks

Delegation shares access but adds no teamwork layer: no assignment, no status, no collision detection. The caps are generous on paper, up to 1,000 delegates on Workspace (25 on a regular Gmail account) with about 40 simultaneous users recommended, but the real limit is coordination, not seats. It suits one inbox one or two people help with, not a team running a queue.

Google's native 2026 shared inbox

The genuinely new option: Google began rolling out a true native shared inbox through 2026, admin-created with a "sent by" field, a real step up from the dated Groups interface. It is free with Workspace and lives closer to Gmail than Collaborative Inbox does.

Where it breaks

Its main limit right now is availability: it is rolling out in phases, so whether you have it depends on your Workspace edition and release track. Where it has landed it is the best native free option; where it has not, Collaborative Inbox or delegation is still the free method. It is a shared-access layer, not a full workflow tool, so the assignment-and-accountability ceiling still applies.

Outlook / Microsoft 365 shared mailbox

If your team is on Microsoft 365 rather than Google, the equivalent free method is a shared mailbox: a native mailbox an admin creates that appears right inside each member's Outlook, with replies sent from the shared address rather than the individual. It is free, no separate license for the mailbox itself, as long as it stays under 50GB, and it includes a shared calendar. To set one up:

1. Sign in to the Microsoft 365 admin center with an Exchange admin role.
2. Go to Teams & Groups > Shared mailboxes.
3. Select Add a shared mailbox, enter a name and address, and Save changes.
4. Under Next steps, select Add members to this mailbox, choose the people who should see and reply to its mail, and add them.

Members access it from their own Outlook (it maps in automatically), on desktop, web, or the Outlook mobile app.

Where it breaks

A shared mailbox gives shared access, not a workflow: no assignment, no collision detection, no analytics, and two people can still reply to the same message. Every member needs their own Microsoft 365 license (the mailbox is free, the people are not), and once it passes 50GB of storage, uses in-place archiving, or goes on litigation hold, it needs a paid Exchange Online Plan 2 license.

The real free tiers (verified)

A handful of paid tools keep a genuinely free tier alive. The limits below are the vendors' own published numbers as of this update, and where a free tier has quietly become a trial since you last checked, that is noted, because these change more often than the roundups that recommend them.

HubSpot - best if you already use the HubSpot CRM

HubSpot's free plan includes a shared inbox (its "help desk" and Conversations tools) with ticketing, live chat, and basic AI routing, attached to the HubSpot CRM. The free plan is capped at 2 users and 1 shared inbox (and 1,000 contacts), so it fits a very small team already living in HubSpot; the jump to paid seats is steep once you outgrow it.

Zoho Desk - best free help-desk shape

Zoho Desk keeps a genuine free-forever tier for up to 3 agents, with email ticketing, a knowledge base, and basic reporting. It is a real free help desk rather than an inbox layer, which is its strength and its cost: no automation, SLAs, live chat, or multichannel on free, all of which sit behind paid tiers.

Thryv Command Center - best free multi-channel for very small teams

Thryv Command Center offers a genuinely free plan for up to 3 users with a centralized inbox across 3 channels, plus team chat, on a plan with no time limit and no card required. Functionality is deliberately limited on free, but for a tiny team wanting more than one channel at zero cost it is a real option.

Open-source, if you can host it

FreeScout - best open-source shared mailbox

FreeScout is licensed under AGPL-3.0 and free to self-host, with unlimited agents, mailboxes, and tickets, plus email integration and collision detection built in; official modules for extra channels and workflows are paid add-ons. Free in license, not in effort: you host it, update it, and fix it yourself, which is a real cost paid in time instead of seats.

Chatwoot - best open-source omnichannel

Chatwoot's community edition is MIT-licensed and free to self-host with no seat cap; email, live chat, and social channels are all in the open-source build, with some advanced features reserved for its paid enterprise edition. Its hosted cloud has a separate free plan capped at 2 agents. Free in license, not in effort: you host it, patch it, and support it yourself, time spent instead of seats.

osTicket - best open-source ticketing veteran

osTicket is GPL-2.0 licensed and completely free to self-host, routing email, web forms, and API requests into a classic ticket queue; a paid osTicket Cloud exists if you would rather not run the server. Free in license, not in effort: you host it, update it, and fix it yourself, a cost paid in time instead of seats.

The last kind of free is open-source: self-hosted help desks with no license fee and no seat cap. Three are worth knowing, and they share one honest catch, noted under each.

Trial, not free: read before you sign up

Several tools that top "free shared inbox" lists are not free at all, they are trials or time-limited programs. Naming them is the point, so you do not lose a week setting one up:

• Freshdesk - free for 6 months for 1 to 2 agents, then paid (Growth from $19 per agent per month). A time-limited program, not a forever-free tier.
• Zoho TeamInbox - 14-day trial only, no free plan (distinct from Zoho Desk, which does have a free tier).
• Helpwise - 7-day trial only, no free plan.
• Front - 14-day trial only, no free plan (paid from $25 per seat per month).
• Loop Email - 14-day trial only, no free plan.
• Missive is the strangest case on this page: it removed its free plan from its pricing page in 2024, but still offers one inside the product, $0 for up to 3 users with 15 days of history. The roundups that call it free and the ones that call it paid-only are both half right. If the hidden tier fits your team, it is real; just know the pricing page will not show it to you.
• Drag - ours, and we will say it plainly: a 7-day trial and no free plan, from $12 per user per month.

Chat-first tools (not email inboxes)

Two tools often listed as free shared inboxes are really live-chat products, free but built for chat, not the email queue this page is about:

• Tawk.to - free and genuinely so, but a live-chat product, the wrong tool for the email-inbox intent of this page.
• Crisp - chat-first: its free plan is a website chat widget with a shared inbox, but email is a paid feature, so the free tier has no email channel and it belongs here rather than in the roster above.

Compare every free option

When free stops being enough

Every option above shares one gap that no free option closes: accountability. A Collaborative Inbox cannot tell you who owns a thread, delegation cannot distribute work, and a shared mailbox cannot show you what is overdue. The moment your team fields enough email that "did anyone reply to this?" becomes a daily question, you have outgrown free, not because the tools got worse but because the job changed from reading mail to running a workflow. That is the line where a paid layer earns its price: Drag turns the Gmail accounts your team already has into shared boards with assignment, statuses, and visibility, from $12 per user per month with a 7-day trial and no card, and no free plan, which we told you up front. If you want the full paid-tools comparison before deciding, our shared inbox software guide ranks the field honestly.

Start with free, and when "who owns this?" becomes a daily question, that is the moment Drag pays for itself.

Drag is $12 per user per month, with a 7-day trial that needs no card and no free plan. Start your free trial.

Frequently asked questions

Is there a completely free shared inbox?

Yes, several. Google Groups Collaborative Inbox and Google's new native shared inbox are free with Workspace, Gmail delegation is free on any Gmail account, and an Outlook shared mailbox is included with Microsoft 365 business plans. A few tools also keep real free tiers, and the open-source options if you can host them.

Is Google Collaborative Inbox good enough for a small team?

For a low volume of email and a small team, yes. Its limits are structural: it lives in a separate interface outside Gmail, has no collision detection, and a reply that misses the Group address disappears from everyone else's view. Fine at dozens of emails a week, painful at hundreds.

Is Drag free?

No. Drag is a paid tool from $12 per user per month, with a 7-day trial that needs no card. This guide exists to give you the genuinely free options first, because if free covers your team's needs, you should use it.

What is the difference between a free shared inbox and a paid one?

Free options give shared access; paid tools add the workflow layer: assignment, statuses, collision detection, automation, and reporting. Teams usually switch not for features but for accountability, when knowing who owns each conversation starts costing real time.
