What is a WhatsApp shared inbox?

A WhatsApp shared inbox is a single dashboard where a whole team answers one WhatsApp Business number. Every incoming message lands in one queue, each conversation can be assigned to a specific agent, teammates leave private notes the customer never sees, and a manager can see who handled what. It runs on the official WhatsApp Business API, not the free consumer app.

The reason teams need it is simple: the WhatsApp Business app was built for one owner with a phone, not for a support desk. Share that phone across five people and it falls apart fast. Two agents answer the same customer, someone marks a chat read and it vanishes from everyone else's view, and there is no record of what was promised. A shared inbox fixes the workflow, not just the login. It gives every agent their own account, one clear owner per conversation, and an audit trail you can coach and report on.

WaBulkSend will put that inbox on the same platform as your WhatsApp CRM and your bulk campaigns, so the conversation, the contact record, and the last broadcast that customer received all sit in one place. The goal is that you answer, then follow up, without switching tools. We are pre-launch and building toward that first release — join the waitlist to get early access.

What we're building into the WaBulkSend team inbox

The inbox is in development. Here's what the first release is scoped to include — everything the free app is missing once more than two people answer the same number.

🎯

One owner per chat

Planned: assign each conversation to a single agent so two people never reply to the same customer, and reassign with a handoff note when a case escalates.

📝

Private internal notes

Planned: leave notes and @mention a teammate right on the conversation. The customer will never see them, so context passes cleanly between shifts.

👥

Unlimited agent logins

Planned: every teammate gets their own login instead of sharing one phone, with no per-seat pricing, so adding staff never inflates the bill.

⚡

Routing and auto-assign

Planned: send new chats to the right team automatically by keyword, hours, or contact tag, so nothing waits in a pile nobody owns.

🕑

Full chat history

Planned: every message, note, and assignment kept against the customer record, so new agents pick up a thread already knowing the story.

💬

Canned replies and templates

Planned: save answers to your most common questions and fire an approved template with merge fields, so replies stay fast and on-brand.

📊

Queue and agent reporting

Planned: see open counts, response times, and who is carrying the load, so you can coach from an audit trail instead of guessing.

🔗

CRM and campaigns attached

Planned: the inbox will sit next to contact records and bulk sending, so a support reply can turn into a follow-up campaign without exporting anything.

🛡️

Official API, ban-safe

Planned: build on Meta's approved WhatsApp Business API, not an unofficial bot, so your number stays compliant as your volume grows.

How to set up a WhatsApp shared inbox

Four steps from a phone-on-someone's-desk to a proper team desk. This is the onboarding flow we are building for the first WaBulkSend release.

Step 01

Connect your number

At launch you will register your business number on the official WhatsApp Business API through WaBulkSend, or port the number your customers already know.

Step 02

Invite your team

You will add every agent with their own login and role. No per-seat charge is planned, so you can put support and sales on the same inbox.

Step 03

Set routing rules

You will decide how new chats get assigned: round-robin, by keyword, by tag, or by business hours, so every message has an owner.

Step 04

Answer as one team

Agents will reply, add notes, and hand off, while managers watch the queue and reporting, so nothing gets lost or double-answered.

WhatsApp Business app vs a shared inbox

Where the free app stops working, and where a real team inbox takes over. The WaBulkSend column describes the first release we are building, not a shipped product.

Capability	WhatsApp Business app	WaBulkSend shared inbox (planned)
People on one number	Primary phone plus a few linked devices	Unlimited agent logins
Per-agent accounts	No, everyone shares one view	Yes, each agent logs in separately
Assign a chat to one owner	No	Yes, with reassignment
Private internal notes	No	Yes, with @mentions
Auto-assignment and routing	No	Yes
Bulk campaigns to the same list	Broadcast lists capped at 256	Unlimited, on the API
Reporting and audit trail	No	Queue and agent reports
Pricing model	Free app, no team features	Planned from $29/mo, no per-seat fee

You still pay WhatsApp's own per-message template fees to Meta on either route. See the WhatsApp Business API pricing breakdown for the current US rates.

Who runs a WhatsApp shared inbox

Any team where more than one person needs to answer the same number.

🎧

Support teams

A ticket-style queue for WhatsApp so questions get answered once, on time, with the history right there. Pairs naturally with your wider customer service workflow.

💼

Sales teams

Inbound WhatsApp leads route to the right rep instantly, and reps see the contact record and past campaigns before they reply.

🛍️

Ecommerce

Order questions, returns, and shipping updates in one queue. WaBulkSend plans to send your order notifications and promotions from that same platform.

🏢

Agencies

Manage several client numbers with separate teams and reporting, all from one login, without buying a seat for every freelancer.

🏥

Clinics and services

Front-desk staff share the appointment line, assign follow-ups, and keep a compliant record of every exchange.

🚗

Dealerships and real estate

High-value inbound goes to the agent who owns that lead, with notes so a colleague can cover without dropping the thread.

WhatsApp shared inbox questions

Can multiple users use one WhatsApp Business number?

Yes. On the official WhatsApp Business API, an unlimited number of agents can log in to a shared inbox and answer the same business number. The free WhatsApp Business app only allows the primary phone plus a handful of linked devices and gives everyone the same view, so it breaks down past two or three people. A shared inbox gives each agent their own login, assigns each chat to one owner, and keeps a full audit trail.

How is a shared inbox different from a WhatsApp CRM?

A shared inbox is the live conversation workspace: the queue, assignment, notes, and replies your agents work in all day. A WhatsApp CRM is the contact database underneath it: profiles, deal stages, tags, and history. WaBulkSend is being built to combine both in one platform, so a chat and the customer record it belongs to will sit side by side. The product is pre-launch and you can join the waitlist for early access.

Does a WhatsApp shared inbox charge per seat?

It does not have to. Many inbox tools charge per agent seat, which punishes you for adding staff. WaBulkSend is planning launch pricing from 29 dollars a month with no per-seat charge, so you will be able to put your whole support and sales team on one number without the bill scaling with headcount. Pricing is not final until launch, and you will still pay WhatsApp's own per-message template fees to Meta.

Can I assign WhatsApp conversations to specific agents?

Assignment is a standard capability of WhatsApp shared inbox software built on the Business API. In WaBulkSend it is planned for the first release: you will be able to assign any conversation to one agent so two people never reply to the same customer, set routing rules that send new chats to the right team, and reassign with a handoff note when a case escalates. Assignment plus internal notes is what stops the double-reply chaos that happens when a team shares one phone.

Do I keep my existing WhatsApp number?

In most cases yes. You can register the number your customers already know onto the WhatsApp Business API. Note that once a number moves to the API it leaves the consumer WhatsApp and Business apps and cannot use them at the same time, and past chat history does not import, so plan the switch for a quiet window.

Is a WhatsApp shared inbox against WhatsApp's rules?

No, as long as it runs on the official WhatsApp Business API. Meta built the API so businesses can connect a number to inbox and helpdesk software and let many agents answer it. What breaks the rules is bulk or automated messaging through an unofficial bot that puppets WhatsApp Web. WaBulkSend is being built on the approved API rather than an unofficial workaround, so your number will stay compliant.
