Summary
Wonderchat is the pick when an AI agent should answer the repeated questions from your help center before anyone opens support@, with the helpdesk on every plan and no per-seat cost.
Front or Missive are the picks for drafting replies together in email, with Missive at the lower seat price.
Hiver keeps the whole shared inbox inside Gmail, with AI agents on every plan.
Zendesk or Freshdesk stay put if your queue already runs on one.
Ranked for teams adopting their first AI customer service software, on who answers first and what three and six people pay a month. Wonderchat publishes this guide.
Shared inbox software lets several people work one address, such as support@, with an owner and a status on every email. Pick it by who answers first.
Eight of the nine tools bill per seat. Every person who answers adds to the bill.
An AI customer service agent can take the repeated questions before the inbox sees them. Say three people share support@, and “How do I add a teammate to our account?” arrives about ten times a week.
Without an agent, someone types that answer ten times. With one, it’s answered from the help center page, and only the variations your docs don’t cover reach a person.
What does a shared inbox tool fix, and what doesn’t it?
A shared inbox tool fixes ownership. Each email gets an owner, a status, and one history, so two people stop answering the same customer.
Assignment, collision detection, internal notes, and rules that sort the mail are the four features Google’s AI answers list for this search.
What it doesn’t fix is the question itself. The teammate question still arrives ten times a week, and a person still answers it, at best by pasting a canned response.
The same question in two inboxes: one answers it every time, the other answers it once from the help center.
The bill is the second thing buyers notice. In Wonderchat’s read of 837 reviews across 18 vendors in September 2026, pricing was the largest complaint theme, 211 of 1,309, and setup came next with 197.
Pricing pain starts with the seat. A tool billed per person costs more with every hire, even when the new hire spends the day answering questions the help center already covers.
So decide who answers first before you pick the inbox. A faster inbox answers the same question faster, and the question keeps coming.
The answer that comes first also has to know when to stop. Asked about a status page its help center doesn’t cover, Wonderchat‘s agent says so and offers a person.
A question the docs don’t cover gets an honest “no page for that” and a way to reach a person.
How were these shared inbox tools compared?
Each tool was reviewed from its own pricing page and docs in November 2026, on the same six points.
Point | What it records |
|---|---|
Who answers first | An AI agent, and how it’s billed, or a person |
Plan for three people | The cheapest plan where three people work one support inbox |
How it bills | Per seat, per user, per agent, or one plan price |
AI on top | Per resolution, per outcome, per session, per conversation, or HubSpot Credits |
Free plan or trial | As the pricing page shows it |
Six people | The same bill after three more hires |
Every bill uses one example team. Three people share support@, about 400 conversations arrive a month, and an AI agent answers 200 of them without a person.
Half is a cautious start, below the 69% median across 687 businesses in Wonderchat’s study of 5,848,078 conversations. Where a tool bills per session or per conversation, all 400 count.
If you’re not sure the team needs more than Gmail yet, start with whether you need a help desk at all.
The 9 best shared inbox tools for support teams
In the same study, 58.5% of a random sample of 5,000 unresolved conversations asked for an answer never documented anywhere the agent could reach. The repeated question is a docs job first and an inbox job second.
The bills are Wonderchat’s arithmetic for the example team, from each vendor’s printed monthly price.
1. Wonderchat, best for an AI agent that answers from your docs before support@
Wonderchat is an AI customer service agent and AI helpdesk in one. The agent answers first, and every conversation it hands over lands in the shared inbox on the same plan, as a ticket with the full chat.
Wonderchat’s month for the example team stays on one plan price as the team grows.
Who answers first: the AI agent, only from the help center, docs, and files you connect, with the source on every reply.
Three and six people: Basic at $149 a month, billed monthly, with 3,000 AI replies and no per-seat cost.
Free plan: 50 AI replies refilled every month, 2 team seats, the shared inbox, and live chat, with no credit card.
The teammate question gets the help center page and a link to it. A variation the page doesn’t cover gets an honest “I can’t find that,” and the visitor can ask for a person.
A handed-over ticket arrives with the whole chat above the reply box. Each one carries one of four statuses (New, On us, On customer, or Closed) and an Overdue badge when it waits too long.
Every handover becomes a ticket with a status, from New to Closed.
A teammate can add an internal note, and when nobody is online the conversation goes to email. “Occasional queries are escalated to a human, and the user answers them from our inbox,” says Luke Tan, CTO and co-founder of Wonderchat.
The $149 a month holds while the 400 conversations average seven AI replies or fewer, by Wonderchat’s arithmetic. Starter, at $39 a month, billed monthly, covers the same three people when the agent needs under 500 AI replies.
Free connects one email address, and paid plans connect more than one.
Routing and assignment rules come with Scale, at $499 a month, billed monthly. See Wonderchat’s plans before you size the queue.
Teams can use Wonderchat‘s helpdesk from the first day or keep their own. Zendesk and Freshdesk sync from Basic, capped at 50 tickets until Scale, and any other help desk receives handovers by email.
About 75% of evaluated conversations on Wonderchat are resolved without a person. Jortt, a Dutch accounting platform, resolves about 92% of roughly 30,000 monthly inquiries that way.
Skip Wonderchat if your team writes every reply together in the inbox and the AI only needs to draft.
2. Front, best for teams that draft replies together in email
Front puts the shared inbox and ticketing on Starter, at $35 a seat billed monthly for up to 10 seats. Front keeps internal comments and shared drafts beside each email.
Front’s month for the example team, with seats plus Autopilot at its starting rate.
Who answers first: Autopilot, an add-on on every plan, starting at $0.39 a conversation, billed with the plan.
Three and six people: from $261 and from $366, seats plus 400 conversations at the starting rate.
Free trial: 14 days with Professional features and no credit card.
The teammate question reaches Autopilot first if you buy it. Without it, a person answers, and two teammates can write the reply together before it goes out.
Starter is for single-channel support, and Professional, at $85 a seat billed monthly, brings email, SMS, and social into one inbox. Copilot, Front‘s drafting assistant for agents, adds $20 a seat a month on Starter and Professional.
Front prints only a starting rate for Autopilot. Ask sales for the full rate before you budget 400 conversations.
Front earns its seat price when drafting together is how your team works, and Autopilot can wait.
3. Missive, best for email teams on a smaller per-user bill
Missive is built around collaborative drafting, with internal threads and chat beside each email. Missive costs $18 a user billed monthly on Starter, which holds up to 5 users.
Missive’s month for the example team, with a person answering every email.
Who answers first: a person. Missive‘s AI assistant drafts replies and finds canned responses, and a teammate sends them.
Three and six people: $54 on Starter, and $180 at six people, who need Productive at $30 a user a month.
Free trial: 30 days on Productive, with no credit card.
The teammate question gets a fast draft and a person’s send, ten times a week. AI drafts run on Missive‘s own AI credits or your own model key.
Missive‘s docs describe drafting together in real time, with teammates’ typing on screen and duplicate replies blocked. At three people, Missive’s bill is the lowest on the list.
Rules, integrations, and API access start on Productive. A team that automates its sorting pays $30 a user a month anyway.
Choose Missive when a person should send every reply and the seat price decides.
4. Hiver, best for a support team that stays inside Gmail
Hiver runs inside Gmail or as its own shared inbox app, Hiver Omni, at the same prices. Hiver puts AI agents in every plan, agents that “triage, resolve requests and act across your systems,” in Hiver’s words.
Hiver’s month for the example team, and the jump at six people from its seat steps.
Who answers first: Hiver‘s AI agents, with no separate AI price on the pricing page.
Three and six people: $105 on Growth at $35 a user billed monthly, and $350 at six people.
Free trial: 7 days on Elite.
The six-person jump comes from Hiver‘s seat steps. Plans start at 2 seats, grow one at a time to 5, and then in steps of 5, so a sixth person means paying for 10.
Growth also brings AI Copilot, which drafts replies and suggests next steps for the person answering.
Collision detection and private notes with @mentions sit on Hiver‘s feature list, and the pricing page doesn’t show their plan. Confirm Growth covers both before a trial.
Hiver is the Gmail team’s pick, as long as headcount fits its steps of 5.
5. Help Scout, best for a simple help desk with a free plan
Help Scout keeps email support simple, and bills its AI per resolution on top of users. Help Scout‘s free plan includes 5 users, 1 inbox, and 1 Docs site, with up to 100 contacts a month.
Help Scout’s month for the example team, with user seats plus AI Answers per resolution.
Who answers first: AI Answers, the Envoy add-on, at $0.75 a resolution, with 3 free months of resolutions on a new account.
Three and six people: $240 on Standard at $30 a user billed monthly, and $330 at six people.
Free plan: 5 users and 1 inbox, enough for three people below 100 contacts a month.
The teammate question goes to AI Answers first when it’s switched on. Collision detection is on every plan and needs no setup, and notes stay internal.
The free plan has no AI Answers, and 400 conversations a month passes its 100-contact cap. Standard adds a second inbox, and round robin routing needs Plus at $54 a user a month.
Start on Help Scout‘s free plan for a clean email help desk, and budget the AI per resolution once you switch it on.
6. Freshdesk, best if Freshdesk already holds your tickets
Freshdesk is a full help desk and omnichannel suite, with ticketing and a shared inbox on every plan. Freshdesk‘s Growth plan costs $23 an agent billed monthly.
Freshdesk’s month for the example team, once the first 500 AI sessions are used.
Who answers first: the Freddy AI Agent, with the first 500 sessions included and $49 per 100 sessions after them.
Three and six people: $265 and $334, with 400 sessions bought in 4 packs.
Free trial: 14 days on Enterprise. The pricing page shows no free plan.
Freshworks’ shared inbox page says you can start with up to two agents for free. The Freshdesk pricing page lists Growth, Pro, and Enterprise with a 14-day trial, and the free plan isn’t on it.
The first 500 sessions are a one-time allowance, so the early months cost only the seats. After that, Freddy’s sessions are bought in packs of 100.
Pro, at $66 an agent billed monthly, adds intelligent routing and multiple SLA policies, and Freddy AI Copilot adds $35 an agent a month, billed monthly.
If Freshdesk is staying, Wonderchat can sit on top of it and sync tickets from Basic.
7. Zendesk, best if your queue already runs on Zendesk triggers
Zendesk sells its entry plan, Support Team, as being for teams “that have outgrown a shared inbox.” Zendesk lists AI agents on Suite Team, at $69 an agent billed monthly.
Zendesk’s month for the example team, with agent seats plus automated resolutions past the included five per agent.
Who answers first: AI agents, with 5 automated resolutions per agent a month included, then $2.00 each, or $1.50 on a commitment.
Three and six people: $577 and $754 pay as you go, or $484.50 and $669 committed.
Free trial: 14 days on Suite Professional, with no free plan.
Each automated resolution counts on the bill. A good AI month costs more on Zendesk.
Support Team already brings automations, triggers, and ticket routing at $25 an agent a month, without the AI agents. Skills-based routing starts on Suite Professional, at $149 an agent billed monthly.
Keep Zendesk if your triggers, routing, and data-center choice already run there. Wonderchat syncs with it from Basic, up to 50 tickets.
8. HubSpot Service Hub, best if your customer records are in HubSpot
HubSpot Service Hub keeps tickets next to the CRM records sales already uses. HubSpot‘s free tools cover up to 2 users, and Starter costs $20 a seat a month.
HubSpot’s month for the example team on Professional, plus a one-time onboarding fee.
Who answers first: the Customer Agent, on Professional and Enterprise, at 50 HubSpot Credits per resolved conversation.
Three and six people: $370 and $670 on Professional at $100 a seat billed monthly, plus a one-time $1,500 onboarding fee.
Free trial: 14 days of the Customer Agent once you buy a Professional or Enterprise seat.
Professional includes 3,000 credits a month, enough for 60 resolutions. The other 140 in the example month cost $70 at $0.01 a credit.
When credits run out, the agent pauses until the reset date unless you buy more, and unused credits don’t roll over. Starter has no Customer Agent, and Enterprise costs $150 a seat a month plus a one-time $3,500 onboarding fee.
HubSpot makes sense when the CRM already decides the tools, with a credit buffer set before launch.
9. Fin, formerly Intercom, best for an AI agent proven at scale
Fin, formerly Intercom, runs as its own help desk or on top of Zendesk, Salesforce, HubSpot, or Freshdesk. Salesforce completed its acquisition of Fin in September 2026, and Fin is proven at scale, with EU hosting too.
Fin’s outcome bill for the example team, before seats.
Who answers first: the Fin AI Agent, at $0.99 per outcome, billed monthly, with no charge when a conversation goes to your team without one.
Three and six people: $198 a month in outcomes, plus Essential seats for each person.
Free trial: 14 days with no cap on outcomes and no credit card.
Fin‘s Essential plan includes the shared inbox and the ticketing system. Round robin assignment comes with Advanced.
On another help desk, Fin needs no seats and has a 50-outcome monthly minimum. The handover to your team adds nothing to the outcome bill, and Copilot for agents costs $35 a user a month.
Fin‘s record at scale is the reason to choose it. Model the outcome bill against a good month before you sign.
What do 3 and 6 people pay a month?
At three people, Missive and Hiver cost less than Wonderchat, and Hiver’s price already includes its AI agents. At six people, every bill that charges per person grows, and Wonderchat’s stays at $149 a month.
Tap a tool for its plan and how the AI part is billed.
Budget for six people before you pick a tool for three. The cheaper tools at three seats charge for every person after that, and Hiver’s seat steps turn six people into ten seats.
Tool and plan | 3 people | 6 people | How the AI part bills |
|---|---|---|---|
Wonderchat Basic | $149 | $149 | AI replies in the plan, no per-seat cost |
Missive Starter, then Productive | $54 | $180 | A person answers; AI drafts on credits |
Hiver Growth | $105 | $350 | AI agents on every plan |
Help Scout Standard | $240 | $330 | $0.75 per resolution |
Front Starter | from $261 | from $366 | Autopilot from $0.39 a conversation |
Freshdesk Growth | $265 | $334 | $49 per 100 sessions after the first 500 |
HubSpot Professional | $370 | $670 | 50 credits per resolution, plus $1,500 once |
Zendesk Suite Team | $577 | $754 | $2.00 per automated resolution past 5 per agent |
Fin Essential | $198 + seats | $198 + seats | $0.99 per outcome |
The example team is three people, 400 conversations a month, and 200 answered by the AI, priced by Wonderchat from each vendor’s monthly price as printed in November 2026.
Which shared inbox tools are left off, and why?
These came up on Google’s first page, in its AI Overview, or in the lists that rank there, and each one answers a narrower case.
Gmail add-ons: Drag, “the shared inbox for Gmail teams,” from $12 a seat a month, and Gmelius, a Gmail-native platform for building AI agents. Hiver covers that case with AI agents on every plan.
Inboxes inside larger suites: Zoho TeamInbox, Zoho’s tool for shared inboxes, and Crisp, which bills per workspace and lists a shared inbox from its free plan.
Google’s collaborative inbox: part of Google Workspace groups, where members can assign a conversation and mark it complete, and a person answers every one.
B2B support in Slack: Pylon, priced at $89 a seat on an annual contract, for customers who write in shared channels.
Field teams and ecommerce: Team Engine, which messages a field workforce on SMS and WhatsApp, and Gorgias, the better choice for a Shopify store that wants the agent to act on orders.
Help desk suites: Kustomer, which Wonderchat syncs with from Scale. For full queues, see the support ticketing systems list and the AI ticketing systems list.
When is another shared inbox the better buy?
Another tool wins when the way your team already works decides the inbox.
If your team drafts every reply together, pick Front, or Missive at the lower seat price, with comments and shared drafts beside each email. If nobody wants to leave Gmail, pick Hiver, with its AI agents in the price, as long as headcount fits its seat steps.
For a free plan and simple email support, Help Scout is the start, with its AI billed per resolution on top of users.
A handover can land in Wonderchat’s helpdesk or in the Zendesk or Freshdesk queue a team already runs.
If Zendesk triggers already route your queue, keep Zendesk. If you run Freshdesk‘s full help desk and omnichannel suite, keep Freshdesk.
Wonderchat syncs with both from Basic. Its AI agent answers first, and the handovers land in the queue you already run.
Fin, formerly Intercom, is proven at scale and hosts in the EU too, which settles it for some teams.
Should your support team start with Wonderchat?
Yes, if your repeated questions are already written down in your help center. The agent answers “How do I add a teammate?” from that page and links it, and it says so when a variation isn’t covered.
The uncovered variation lands in the shared inbox as a ticket with the full chat, and a teammate takes it, or it goes to email when nobody is online. There’s no per-seat cost, and the free plan includes 2 team seats.
Paste your help center URL into Wonderchat, ask your hardest support@ question, then one your docs can’t answer, and see the source and the honest miss. Start for free, or book a demo to see the shared inbox with your own team’s questions.
Frequently asked questions
Which shared inbox software is best for a support team?
Wonderchat, when an AI agent should answer the repeated questions from your docs before anyone opens support@. Front or Missive are the picks for drafting replies together, and Hiver for a team that stays in Gmail.
How much does shared inbox software cost for three people?
Missive’s $54 a month is the lowest bill for the example team of three, with a person answering every email, and Zendesk’s $577 is the highest, by Wonderchat’s arithmetic in November 2026. Wonderchat’s Basic is $149 a month, billed monthly, with the AI agent answering first.
Is there free shared inbox software?
Help Scout’s free plan covers 5 users and 1 inbox, HubSpot’s free tools cover 2 users, and Wonderchat’s free plan includes 2 team seats and one email address.
How do you stop two people answering the same email?
Give every email one owner and a status, and use collision detection where the tool has it. Fewer emails reach the inbox at all when an AI agent answers the documented questions first.
Is Google’s collaborative inbox enough for a support team?
It works while one person can own each conversation and nothing repeats. Google’s collaborative inbox lets members assign and complete conversations, and a person answers every one.
