3 Hiver Alternatives for Shared Inboxes and AI Follow-Up

The Hiver alternative to choose depends on what happens after an email arrives: Carly for AI follow-up and scheduling, Front for a staffed customer-service workspace, or Trengo for a team managing conversations across channels. Keep Hiver on the shortlist if your main need is shared-inbox ownership and your existing process works.

A support manager and a business owner can both search for a shared inbox while needing very different products. The manager wants assignments, service levels and reporting. The owner wants someone to handle the inquiry, find an appointment and leave useful context without requiring another hour in the inbox.

This comparison is published by Carly. We checked public vendor information and original customer reviews on November 9, 2026; we did not run a head-to-head product trial. The recommendations below distinguish documented features from the workflows we suggest testing.

A Hiver customer’s complaint was about implementation effort

Emma M., a small-business student success manager, gave Hiver 4.5/5 in a G2 review updated October 30, 2026. She praised her customer success manager and visibility into student communications, while writing: “The new AI features can take a lot of effort to integrate into our business workflows.” G2 marked the review incentivized through a seller invitation; its original date was February 18, 2025.

Hiver’s response offered further help and expressed support for developing the team’s chatbot. The criticism identifies work a buyer must budget for: turning a feature into a dependable process. It is not evidence that Hiver lacks AI or that every customer finds setup difficult. The review concerns the Hiver in Gmail listing; it should not be repurposed as a test of every Hiver Omni feature.

Before switching, identify the unfinished implementation. Is the knowledge base incomplete? Does nobody own exception handling? Are the team’s rules inconsistent? Those problems can follow you into another product. Ask each vendor to demonstrate the same unresolved case, with your policy and a realistic customer message.

Hiver pricing: compare the support plan you actually need

The current Hiver Omni pricing page lists Growth at $25 per user/month annually or $35 monthly; Pro at $55 or $65; and Elite at $85 or $95. Growth already lists AI Agents, Copilot and Skills. Pro adds capabilities such as SLAs, CSAT, advanced analytics and premium integrations. Voice is an add-on.

For five users, those monthly-billed seat totals are $175, $325 and $475 before other charges. These are arithmetic examples, not complete quotes. The relevant comparison for a team that needs service-level reporting is usually the qualifying plan, not the entry price in an advertisement. Confirm seats, AI usage and channel charges for your configuration.

There is a separate Hiver pricing guide if your immediate question is the subscription. Here, the more important issue is whether you are replacing a support operation or adding help around it.

When keeping Hiver makes sense

Keep Hiver when agents know the workflow, assignments are clear and the reports answer the manager’s questions. A single recurring scheduling task does not automatically justify moving every support conversation. Try resolving that task inside the existing setup before taking on a migration.

Also distinguish a product limitation from an unfinished configuration. If replies lack the right information, review the approved answers. If urgent conversations wait, inspect ownership and coverage. Switching tools can improve the interface or available controls, but it does not decide who should answer an unusual customer request.

Three alternatives, three different operating models

Product	Best reason to evaluate it	What to verify before switching
Carly	Delegate email, calendar and customer follow-up to an AI agent	Your booking rules, exceptions and separately billed communications
Front	Give human agents a collaborative service workspace	Channel tier, automation limits and AI add-ons
Trengo	Organize customer conversations across channels	Included conversations, users and the definition of billable usage

The table is a shortlist by job, not a reliability ranking. None of the reviewed material establishes that one vendor resolves your particular inquiries more accurately.

1. Carly: when the inquiry needs an appointment and follow-up

Carly is worth evaluating when the work extends beyond assigning an email. Its strengths include email labeling and sorting, advanced calendar work, phone and SMS. You can give the agent specific rules for how a request should be handled and manage work inside ChatGPT, Claude, Grok Bot, Meta Muse or Perplexity. Carly connects to thousands of apps.

Consider a small consultancy receiving requests for an introductory call. Some prospects fit the service, some need an existing client’s account manager, and some want a custom arrangement the business has never approved. A useful assistant should distinguish those paths, offer suitable meeting times and preserve the original request for the person taking the meeting.

Start with one approved service and one calendar. Define the appointment length, time zone, preparation time and questions that require a person. Give the agent the exact information it may use about the service. A request for a discount or contractual promise should have an explicit escalation path.

This makes the demonstration measurable. Check whether the proposed time is actually available, whether the calendar entry contains the customer’s context, and whether an ambiguous request reaches the right person. A polished email alone does not prove the workflow works.

Carly’s cost and limits in this comparison

Free Zapier-style workflows; AI agents from $35/month. Organization seats are $35 per seat/month. Business SMS, calling and the AI receptionist are separately billed add-ons; AI usage can also affect the configuration and cost. Do not treat the entry price as an all-inclusive support or telephone bill.

Carly is not an automatic replacement for every support-management requirement. If your decision depends on a particular SLA dashboard, queue control or quality-assurance process, demonstrate it explicitly. It may make more sense to retain the service workspace and delegate a bounded administrative task. The phone and email overview helps separate those communications needs from shared-inbox management.

2. Front: when the team still owns the support queue

Front’s plans are organized around customer-service work. Annual pricing lists Starter at $25 per seat/month for up to 10 seats, Professional at $65 for up to 50, and Enterprise at $105. Starter is limited to a single channel type; Professional adds omnichannel support and more advanced reporting. Autopilot starts at $0.39 per conversation, while Copilot is a $20 per seat/month add-on on Starter and Professional and included in Enterprise.

That structure matters if your Hiver replacement must combine email and messaging. Do not assume the entry plan covers the same channel mix as a higher tier. Request the seat cost and the AI charges together.

Front is the alternative to investigate when the central problem is coordination among people: a teammate needs to review a response, a manager needs to see ownership, or a conversation crosses departments. It is also an AI-enabled platform, so the decision should not be framed as human-only Front versus AI-enabled Carly.

For a useful demonstration, give Front a customer thread that contains an account question and a request to schedule a review. Have two employees collaborate on it, then inspect what the next employee sees. Evaluate the continuity of the handoff and the final record, not just the first reply.

The tradeoff is adopting and paying for a service workspace. A solo owner who mainly wants calendar coordination may find that a larger support environment solves more problems than they currently have. A growing support team may value exactly those controls.

3. Trengo: when channel coverage drives the decision

Trengo’s pricing combines users and conversation allowances. Boost lists 10 users and 6,000 conversations per year at $299/month with annual billing or $349 monthly. Pro lists 20 users and 18,000 annual conversations at $499 or $599. The annual conversation allowance is important: it is not the same as a monthly message allowance.

Trengo deserves a look when customers arrive through several messaging channels and the team wants a common place to handle them. That buying case differs from wanting an assistant to manage an executive’s calendar or sort personal email.

Map the actual customer journey. Someone might begin with a website question and later send a message from another channel. Ask how staff recognize that person, see the earlier context and avoid duplicate follow-up. Show the vendor a real example with personal information removed.

Ask for the definition of a conversation and how reopened or repeated interactions affect usage. Your busiest week is more useful for sizing than an average that hides seasonal demand. Our Trengo alternatives comparison explores that channel-focused decision in more detail.

Moving the inbox without losing responsibility

Treat migration as a transfer of obligations, not just messages. Open conversations contain promises: a response due tomorrow, a refund awaiting approval, a call that someone agreed to arrange. Exporting an email does not guarantee that the new system carries its owner and next action.

Before moving, record which inboxes exist, who owns them, which rules assign work and which reports the team relies on. Select a small sample of open cases across departments. Verify that the new process preserves the customer’s identity, the last commitment and the responsible employee.

Separate historical reporting from live work. If the old system calculates response times differently, a new dashboard may not be comparable. Keep an accessible record of the old definitions so an apparent improvement does not simply reflect a changed measurement.

Finally, define the cutover. Staff need to know where new messages arrive and where old conversations finish. Running two systems without an ownership rule can create duplicate answers even when each system works correctly.

Bring one unresolved workflow to the demonstration

For Carly, a useful starting brief is: handle introductory-call inquiries for one service, label existing-customer requests for their account owner, offer times from the approved calendar, and ask for help on custom pricing. Include one ordinary inquiry and one exception.

Have the demonstration end with the calendar event and the handoff record visible. If your real requirement is support queue management, take that same case to Front and Hiver. If it is cross-channel continuity, include Trengo. Choose the product that demonstrates the work your team needs to stop doing manually.

Build your first inquiry-to-appointment workflow

Bring your inbox rules, calendar and one real handoff to a Carly setup call.

Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.

# Connect Carly Teams to an AI app

> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.

MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)

## Setup

Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.

1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.

2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.

3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.

4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.

## Email, calendars and workflows

Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.
