Sendiee Teambox

Sendiee Teambox is a shared inbox for support and sales teams, bringing WhatsApp, Instagram, Messenger and LINE conversations into one queue. Messages from a customer across supported channels can be grouped into a single thread. Teams can route conversations by conditions, assign them manually, or use AI handover to send a human request to a team and round-robin an agent with a summary. Roles include Admin, Manager, Team Lead and Agent, with conversation visibility and team management tied to roles. Inbox tools include filters, custom statuses, assignment history and insights on volume, response time and resolution. AI features include per-chat controls, manager instructions, translation, summaries and quick replies. Apps are available for web, macOS, Windows, iPhone, iPad and Android, with push notifications and biometric locks on mobile. The free plan includes one channel, one AI assistant, 1,000 contacts, 1,000 conversations per month and one team member. The pricing note lists paid plans from $12/mo (annual) and a 14-day trial.

Teambox brings multi-channel conversations, team controls and AI tools into a shared inbox, with web and mobile apps. Check the plan limits and channel availability against your team's needs before choosing a paid tier.

Teambox suits support and sales teams handling customer conversations across social and messaging channels. Its roles, routing controls and team insights may help teams that need to assign and monitor shared conversations.

Overview

Sendiee Teambox is a shared inbox for support and sales teams handling customer messages across several channels. It is best suited to teams that need shared ownership, routing and role-based access; its value depends on whether a plan’s channel, conversation and team limits fit the workload.

Grouping a customer’s messages from supported channels into one thread can give agents a more continuous conversation. The mix of routing and AI tools is substantial, but smaller plans restrict channels and staffing, and Creator plans do not include WhatsApp.

Key features

Conversation routing and team controls

Teambox brings WhatsApp, Instagram, Messenger and LINE into a shared queue, with cross-channel messages from one customer appearing in a single thread. Condition-based routing and manual assignment suit teams that want either rules-driven triage or direct control. AI handover sends a request for a person to a team, assigns an agent in rotation and provides a summary, which can ease transfers without removing human ownership.

Admin, Manager, Team Lead and Agent roles, role-based conversation visibility and team management give teams ways to divide responsibility and access. Advanced filters, custom statuses and assignment history help organize work, while team and agent insights track volume, response time and resolution. These controls matter most when several people share a queue; a small team with straightforward message handling may not need the full structure.

AI, integrations and security

AI tools include per-chat controls, live manager instructions, translation, summaries and quick replies. This range can support consistent responses and handoffs, though the free plan allows only one AI assistant. Shopify, Zoho and Meta Pixel (CAPI) integrations are included with Pro and Business; Enterprise supports custom integrations. That makes the higher tiers more relevant to teams that need those connections.

Sendiee says it encrypts data at rest with AES-256 and in transit with TLS 1.2+. It offers a SOC 2 Type II report under NDA, and its policy says Type I was attested in 2025.

Pricing

Teambox uses a freemium model, with a free plan and paid tiers billed annually. The apps are free downloads, but access to the shared inbox is tied to eligible plans. A 14-day trial is offered. The pricing note says paid plans start at $12/mo (annual), while the plan prices below are shown as annual amounts.

Pro and Business also list Shopify, Zoho and Meta Pixel (CAPI). Priority support begins with Pro, while an account manager is included with Business and Enterprise. Compare the annual amounts and each tier’s caps carefully: the channel and staffing differences can matter more than the headline price.

Platforms

Teambox is available on the web, macOS, Windows, iPhone and iPad, and Android. The apps include push notifications and mobile biometric locks, useful for teams responding away from a desktop and for limiting access to a mobile inbox.

Who it's for

Teambox is a strong fit for support or sales teams that handle conversations across multiple channels and need assignment rules, clear roles and visibility into response and resolution. Pro and Business are the more relevant options when a team needs the shared inbox, integrations or higher channel and conversation limits. It is less suitable for teams that need WhatsApp on a Creator plan, or for those whose required agent, channel or contact count exceeds a chosen tier’s caps.

Pros and cons

• Pros: Cross-channel threads can keep a customer’s messages together rather than split across separate conversations.
• Pros: Routing, manual assignment and AI handover cover both automated triage and human ownership.
• Pros: Filters, statuses, assignment history and team insights support shared queue management.
• Cons: Free is limited to one channel, one team member and 1,000 conversations per month.
• Cons: Creator Lite and Creator Plus exclude WhatsApp, despite including the shared inbox.
• Cons: Pro has a five-agent cap and Business a ten-agent cap, so teams must weigh those limits alongside the user and conversation allowances.

Alternatives

Mixdesk is worth comparing for teams that want a free plan with 10 conversations and 10 connected channel accounts, or an Essential plan priced at $49 a month. Its free plan has no AI messages and only 100 translation characters.

Soclo may suit users focused on publishing social content: its free plan allows account connections and manual publishing but has 0 credits each month. Its Starter plan is $7.99 a month.

Upcellia is another free option for a very small inbox: its free tier allows one channel, one user, one mailbox and 100 conversations per month, with no AI agents or automations.

Desku AI Chatbot Builder is an alternative for teams considering a chatbot-focused product, with a free plan for two agents and one inbox and a Growth plan at $39 a month for six agents.

Superplural Omni is a paid alternative.

Trengo is a paid option with a free trial; its Boost plan is €299 a month billed annually for 10 users and 6,000 conversations per year.

Chattrik Omni Channel is a paid alternative with a Starter plan at $14.99 a month per seat, including an AI chatbot and omnichannel features.

Medal Social Inbox may appeal to creators seeking a paid social inbox; its Creator plan is $129 a month, billed at $387 quarterly or $1,548 yearly, for two team members and 13+ social channels.

Verdict

Choose Sendiee Teambox if your support or sales team needs a shared, multi-channel queue with practical routing, role controls and AI-assisted handoffs. Its strongest case is the combination of cross-channel threads and team management. Look elsewhere if WhatsApp is essential on a Creator tier, or if your team cannot fit the plan’s channel, agent or conversation limits.
