Quick summary
Hiver is built for complex support, with two products designed around how teams work. Hiver Omni brings email, chat, voice, and other channels into one place, while Hiver in Gmail gives teams a Gmail-native way to manage shared inboxes, ownership, and collaboration. Front and Missive are other strong options for teams evaluating shared inbox software.
| Tool | Best for | Starting price |
|---|---|---|
| Hiver | Support teams that need AI-driven shared inboxes across email, chat, and voice | $25/user/mo |
| Front | Operations-heavy teams routing high volumes of external messages | $25/seat/mo |
| Missive | Small teams that want a shared inbox with built-in team chat | $14/user/mo |
Shared inboxes work until they don’t
Your team has three people watching support@. Replies go out the same day. Then you hire a fourth, a fifth, and by the eighth nobody can tell who’s handling what. A customer gets two conflicting answers in the same hour. Your ops lead spends Monday mornings untangling threads from the weekend.
Shared inbox software exists to solve exactly that problem, but the tools take very different approaches. Which one fits depends on how many channels you need, how much AI you want involved, and what you’re willing to pay per user.
Why listen to us?
We’ve been building Hiver for more than a decade, and today 10,000+ teams, including Flexport, Gusto, and Ping Identity, use it to manage shared inboxes and customer conversations. That experience shows up in how teams scale with Hiver. Flexport, for example, manages around 1,000 customer emails a month with Hiver and cut response times by 50%, while also putting an end to missed emails. It shows how teams can scale a shared inbox while keeping ownership clear and every request accounted for.
What is shared inbox software?
Shared inbox software gives your whole team access to one inbox, like support@ or sales@, without forwarding emails around or CCing people manually. Everyone sees the same queue, and every message has a clear owner.
It adds what regular email clients don’t have. You can assign conversations, track whether they’re open or resolved, and leave internal notes on a thread. You can also set up automations to route messages to the right person. Some tools go further and pull in live chat, social, and voice, so your team works from one place.
It all comes down to visibility. If you’re a Director of Support with 20 support reps, you shouldn’t have to ask “dDid anyone reply to this?” That answer should already be on your screen.
Why shared inbox software matters for your team
- Duplicate replies disappear: When two reps reply to the same customer, it looks unprofessional and wastes time. Shared inbox tools show who’s viewing or drafting a reply on a thread, so you’ll know before you start typing that it’s already covered.
- Accountability is built in: Every conversation gets assigned to a person, tagged by status, and tracked from first reply to resolution. Managers can see workload across the team and spot bottlenecks without asking for an update.
- Context stays with the conversation: Internal notes, previous interactions, and customer data live right next to the thread. When a support rep picks up a conversation they didn’t start, they don’t need to dig through old emails for background.
- Routing gets automatic: Most shared inbox tools let you build rules that assign conversations by subject line, sender, priority, or time of day. Your team stops spending the first ten minutes of every shift triaging manually. You can read more about how help desk automation works.
- Performance becomes measurable: First response time, resolution time, and CSAT scores give support leaders the data they need. You can make staffing decisions, justify new hires, and report to leadership with numbers you can actually point to.

1. Hiver
Hiver is the agentic omnichannel customer service platform built for complex support. With Hiver, every email request can be tracked from intake to resolution, with a clear owner, status, and full conversation history. When an issue needs input from another team, reps can bring them in with internal notes and @mentions without forwarding threads or losing context. Workflows automatically route, assign, and escalate requests, while integrations with your CRM, help center, and other systems bring the information teams need into the conversation.
That connected context also gives Hiver’s AI more to work with. AI Agents can understand incoming requests, pull information from connected systems, follow your procedures, take action, and resolve requests end to end. When a person is handling the request, AI Copilot can surface relevant information, show how similar issues were handled, draft replies, and suggest next steps.
How you set it up depends on where your team works today. If you’re on Gmail, Hiver in Gmail turns your existing inbox into a shared workspace. Teams not on Gmail, or managing chat, Slack, voice, and WhatsApp alongside email, use Hiver Omni, where email is one part of a single queue across every channel.
Hiver also brings reporting across teams, inboxes, and channels into one place, so managers can track volume, response and resolution times, SLA performance, and team productivity.
Key features
- Omnichannel Inbox: bring email, chat, voice, SMS, Slack, and social into one queue where every message stays linked to the customer record.
- Ticketing: every request gets an owner, a status, and a priority the moment it lands.
- Cross-team collaboration: loop in finance, product, or engineering without losing conversation history, private notes, or handoff context.
- Workflow automation: build routing, triage, and escalation rules in natural language, no visual rule builder to learn first.
- Analytics: reporting across teams, inboxes, and channels comes together in one dashboard, tracking volume, response times, resolutions, SLAs, and team performance.
- AI Agents: assign incoming requests to AI that reads intent, follows your procedures, and resolves or hands off when judgment is needed.
- AI Copilot: when a request needs a person, Copilot gathers context and drafts the reply in your team’s tone, ready for review before it is sent.
- AI QA: review every conversation against your quality standards automatically, across full volume.
Pricing
Hiver’s plans are billed annually, per user per month:
- Growth: $25/user/mo
- Pro: $55/user/mo
- Elite: $85/user/mo
Pros
- Teams can use Hiver Omni to bring email, chat, voice, Slack, and social conversations into one workspace, or Hiver in Gmail to manage shared inboxes directly from Gmail.
- AI Agents resolve requests and learn from every correction, so accuracy compounds over time.
- Workflows and SLAs are configurable in natural language, no visual rule builder to learn first
Cons
- AI Agents improve as your team resolves more conversations, so the first week won’t match the tenth.
2. Front
Front is a shared inbox platform for teams that route high volumes of external messages across email, SMS, live chat, and social. It can work well for operations-heavy teams in logistics, financial services, and account management, where customer messages may involve input from multiple departments.
Front organizes everything around shared inboxes with internal comments and @-mentions on each conversation, so the coordination happens right next to the message. It also offers AI add-ons. Autopilot resolves routine conversations end to end, and Copilot drafts replies and summarizes threads. Smart QA scores rep performance across your queue.
Those AI features come on top of the base seat cost, so they can significantly increase the overall price. Autopilot is usage-based, while Copilot and Smart QA are charged separately per seat.
Key features
- Omnichannel Shared Inboxes: Pull email, SMS, live chat, social, and voice into inboxes that multiple teams can access.
- Workflow Automation: Build rules that route, tag, and escalate messages by keywords, sender, or SLA timers.
- AI Autopilot: Resolve routine conversations end to end without support reps involvement, billed per conversation.
- Analytics and Reporting: Track response times, resolution rates, SLA attainment, and team workload in customizable dashboards.
Pricing
- Starter: $25/seat/mo (max 10 seats)
- Professional: $65/seat/mo (max 50 seats)
- Enterprise: $105/seat/mo
AI add-ons (extra cost):
- Autopilot: $0.05/conversation
- Copilot: $20/seat/mo
- Smart QA: $20/seat/mo
- Smart CSAT: $10/seat/mo (included in Enterprise)
Pros
- Strong fit for operations-heavy teams in logistics, finance, and account management where messages touch multiple departments.
- Internal comments and @-mentions keep coordination visible right inside the conversation thread.
- Autopilot’s per-conversation pricing means you’ll pay only for the AI volume you actually use.
Cons
- AI features are paid add-ons on top of base pricing, so the full-featured cost per user climbs quickly.
- Starter caps at 10 seats and Professional at 50, so growing teams hit plan-change thresholds.
- Add-on layers make budgeting less predictable than a flat per-user model.
3. Help Scout
Help Scout is a shared inbox tool for small and mid-sized support teams that want a clean, email-focused experience. It avoids the ticket-queue look that some tools default to, so conversations feel more like email than a support desk.
The platform covers email, live chat (through its Beacon widget), and social messaging. Help Scout offers a free plan for up to 5 users. That makes it a practical starting point if you’re moving off a basic Gmail or Outlook setup. AI features include AI Answers, AI Drafts, and AI Summarize. AI Answers pulls from your Docs knowledge base to draft replies, but it’s billed separately at $0.75 per resolution.
Key features
- Shared Inbox: Manage email conversations with assignment, collision detection, tagging, and internal notes in an interface that feels like personal email.
- Beacon Widget: Add live chat and a self-serve help center to your site through a single embeddable widget.
- Docs Knowledge Base: Build and publish a searchable help center that AI Answers draws from when drafting replies.
- AI Answers: Draft responses automatically using your Docs articles, billed per resolution.
Pricing
- Free: $0 (up to 5 users, 1 inbox)
- Standard: $25/user/mo
- Plus: $45/user/mo
- Pro: $75/user/mo (annual only)
AI Answers costs $0.75 per resolution on top of any plan. Additional inboxes are $10/mo each.
Pros
- Clean, email-like interface that feels familiar to teams switching from Gmail or Outlook.
- Free plan for up to 5 users makes it a low-risk starting point.
- Beacon widget combines live chat and self-serve help in one embed.
Cons
- Limited automation options for teams with complex or highly customized support workflows.
- Fewer omnichannel capabilities compared with larger, more comprehensive helpdesk platforms.
- Reporting and analytics may feel limited for teams needing deeper insights.
4. Missive
Missive combines a shared inbox with built-in team chat, so your team doesn’t need a separate tool to discuss customer messages internally. You can talk about a thread in a side chat and draft a reply together with live co-editing. When it’s ready, you send it from the same window.
Missive supports email, live chat, SMS, and social messaging, bringing multiple customer conversations into one shared workspace. Its AI features require your own OpenAI API key, and its AI capabilities are more limited than those built into platforms like Hiver and Front. For a closer comparison, see Front vs. Missive.
Key features
- Shared Inbox + Team Chat: Discuss customer messages in internal side conversations without leaving the inbox view.
- Live Collaborative Drafting: Co-edit a reply with teammates before sending, so you don’t have to forward the thread for a second opinion.
- Rules and Automations: Build routing, tagging, and assignment rules by sender, subject, keywords, or custom conditions.
- Multi-channel Support: Manage email, live chat, SMS, and social conversations from a single view.
Pricing
- Free: $0 (up to 3 users, 15-day message history)
- Starter: $14/user/mo (max 5 users)
- Productive: $24/user/mo (max 50 users)
- Business: $36/user/mo (unlimited users)
AI features require your own OpenAI API key and the Productive plan or above.
Pros
- Built-in team chat means you don’t have to jump to Slack or Teams for internal discussions about customer threads.
- Live collaborative drafting lets teammates co-edit a reply before it goes out, which is rare in this category.
- Brings customer conversations and internal team discussions together in one place.
Cons
- AI features require bringing your own OpenAI key, so setup is more technical and costs are harder to predict.
- Starter plan caps at 5 users, so even a small team can outgrow it quickly.
- No native voice or phone support channel.
5. Gmelius
Gmelius is a shared inbox tool that lives entirely inside Gmail. It adds shared labels, assignment, internal notes, and basic automations on top of Gmail’s interface. If your team already runs on Google Workspace, there’s nothing new to learn.
The tradeoff is scope. Gmelius only works with email inside Gmail, so it doesn’t cover live chat, voice, SMS, or social channels. Each plan also caps your monthly conversation count. That means high-volume teams need to watch usage closely.
Key features
- Gmail-native Shared Inbox: Turn Gmail labels into shared inboxes with assignment, status tracking, and internal notes, all without leaving your inbox.
- Kanban Boards: Visualize conversations as tasks on a board view for project-style tracking alongside your inbox.
- Email Sequences: Build automated follow-up sequences for outbound or internal workflows.
- Workflow Automation: Create rules for assignment, tagging, and routing by sender, keywords, or labels.
Pricing
- Meli: $19/user/mo (5,000 conversations/mo)
- Growth: $25/user/mo (50,000 conversations/mo)
- Pro: $40/user/mo (100,000 conversations/mo)
- Enterprise: custom (min 50 users)
Pros
- Lives entirely inside Gmail, so there’s zero learning curve for Google Workspace teams.
- Kanban board view gives a visual way to track conversations as tasks alongside the inbox.
- Automates repetitive tasks like assigning, tagging, and routing conversations.
Cons
- Gmail-only, with no live chat, voice, SMS, or social support, so you’ll need a separate tool for anything outside email.
- Conversation caps on every plan (5,000 to 100,000/mo) can force a plan upgrade as volume grows.
- No native AI features, so you’ll rely on Gmail’s own AI or third-party integrations.
How to choose
- Complex support across multiple channels: Hiver Omni brings email, chat, voice, Slack, and social into one queue with AI Agents that resolve requests end to end; Hiver in Gmail keeps it all inside the inbox you already use.

- Small team, under 10 people, budget-conscious: Missive gives you a shared inbox plus team chat starting at $14/user/mo.

- Clean, email-focused, simple to start: Help Scout has a genuine free plan for up to 5 users.

FAQs
What is the best shared inbox software?
Hiver is the strongest all-round pick. Hiver Omni covers email, chat, voice, and social with built-in AI Agents, while Hiver in Gmail keeps everything inside your inbox. For smaller teams on a tight budget, Missive starts at $14/user/mo with built-in team chat.
Can I use a shared inbox with Gmail?
Yes. Two tools on this list work directly inside Gmail. Hiver in Gmail turns your Gmail workspace into a shared inbox with assignment, notes, and automation. Gmelius does something similar, though it’s email-only and caps conversations per month.
How is shared inbox software different from a helpdesk?
A shared inbox manages team email and messaging in a single queue. A helpdesk adds ticketing, SLA management, knowledge bases, and reporting on top of that. Some tools, like Hiver, do both, so you get a shared inbox with AI Agents, SLA tracking, and analytics in one platform.
Do shared inbox tools support channels beyond email?
Some do and some don’t. Hiver Omni and Front support email, chat, voice, SMS, and social. Missive covers email, chat, SMS, and social, while Help Scout handles email, chat, and social. Gmelius is email-only and works inside Gmail.
How much does shared inbox software cost?
Pricing ranges from free to over $100/user/mo depending on the plan. Help Scout offers a genuine free plan; Hiver starts at $25/user/mo instead. Missive starts at $14/user/mo, and Gmelius starts at $19/user/mo. Front starts at $25/seat/mo, but AI add-ons push the effective cost higher.
What’s the difference between a shared inbox and just CC’ing the team or using a distribution list?
A distribution list or CC chain gets the message to everyone, but it doesn’t tell anyone who’s actually responsible for replying. Everyone sees it, no one owns it, and that’s exactly how two people end up answering the same customer differently, or nobody answers at all because each person assumes someone else has it. A shared inbox adds the piece a distribution list is missing: clear assignment, status tracking, and visibility into whether a reply’s already in progress, so the team knows who owns what before anyone starts typing.
