---# Unified Inbox for Coaches: One Screen for Every DM

> A unified inbox for coaches pulls Instagram, WhatsApp, Telegram, and Messenger DMs into one screen. You reply from a single place, route each lead by channel or intent, and stop switching apps mid-conversation. Luca runs this inbox, drafts replies the way you write, and moves leads toward a booked call. Auto-send is on by default on every channel, and you can switch any channel to review.

## Key takeaways

- A unified inbox merges Instagram, WhatsApp, Telegram, and Messenger DMs into one screen, so you answer from one place.
- Leads pick the app, not you. Meta counted over 1 billion active message threads a day between people and businesses across its apps in 2026.
- Every app has its own reply window and its own API rules. The inbox holds them so you don't have to.
- Routing, assignment, and internal notes turn a merged list into a system you can hand to a second person.
- Luca runs the inbox and drafts replies the way you write. Auto-send is on by default on every channel, and you can switch any channel to review.

A unified inbox for coaches puts Instagram, WhatsApp, Telegram, and Messenger DMs on one screen, so a new DM shows up in the same place whichever app it came from. You need one because leads don't pick one app. Some DM you on Instagram after a Reel. Others message WhatsApp because a friend referred you. A few land in Telegram or Messenger. When every app is its own tab, hot leads sit unread while you're looking at the wrong one.

## What is a unified inbox for coaches?

A unified inbox is one screen that shows every DM from every app. It does five jobs. Gather the DMs. Show who sent each one, and from where. Let you answer in one place. Sort by priority. Track each lead through to a booked call. Underneath, it holds a live link to each app, called an API. You work from one shared record that keeps in step with each app, not a copy of one. If you mostly need to organize leads on Instagram, an [Instagram CRM](/blog/instagram-crm) setup may be enough.

Your pipeline is spread across apps, and none of them plan to join up. WhatsApp passed 3 billion monthly users in 2025, Instagram about 2 billion, and Telegram 1 billion (TechCrunch; Backlinko).

**Chart:** WhatsApp reaches more than 3 billion monthly users, Instagram about 2 billion, and Telegram 1 billion in 2025, so coaches face leads spread across every major channel. (Source: TechCrunch (WhatsApp, 2025) and Backlinko (Instagram, Telegram).)

### What a unified inbox is not

- **Not a mass-DM tool.** Every app here only lets you answer people who messaged you first. A seller promising cold outreach at scale is describing a ban.
- **Not a chatbot.** A menu tree that pushes questions away has a different job. A sales inbox moves a thread toward a call.
- **Not a CRM.** It holds threads, not invoices, program stages, or your session notes.
- **Not a full copy of each app.** Vanish mode, WhatsApp voice calls, and Telegram polls don't come through the API.

Luca is the DM sales platform for coaches, creators, and experts that runs the inbox for you. It reads DMs across apps, drafts replies the way you write, qualifies the lead, and moves toward the call. For the thinking behind the mix, see the [multi-channel DM strategy](/blog/multi-channel-dm-playbook) pillar.

## What problem does a unified inbox actually solve?

It solves the cost of switching. Not the second you lose tapping across. The twenty after it, where you can't recall what the lead in front of you already said. Workers flipping between apps did it about **1,200 times a day** and lost just under four hours a week getting their bearings again, roughly 9% of the working week ([Harvard Business Review, 2022](https://hbr.org/2022/08/how-much-time-and-energy-do-we-waste-toggling-between-applications)). Four DM apps is a small version of the same bill.

The second problem is quieter. Nobody holds one record of the lead. Someone starts in a Story reply, moves to WhatsApp, then comes back three weeks later. You make them tell you the whole thing again, because the first half sits in an app you aren't looking at.

And the volume keeps climbing. Meta counted more than **1 billion active threads a day** between people and businesses across its apps ([Meta, 2026](https://about.fb.com/news/2026/06/meta-business-agent/)). Your share of that is small. It still arrives in four places.

## Which unified inbox should a coach choose?

There's no single best tool, because these products were built for different buyers. A support desk, an agency team, and a coach closing on their own want different things from the same screen.

**How we evaluated, and our conflict of interest.** We're a vendor and Luca sits in this table, so read our verdict on it accordingly. We scored each tool on four things you can check without a demo. Which DM channels it handles itself. The entry price on its public pricing page. How the bill grows. And whether one person can run it without help. Prices were verified in August 2026. How deep each one goes as a support desk, where Front and Chatwoot lead, is outside what we tested.

| Tool | Native DM channels | Entry price (published) | Billing model | Best for |
| --- | --- | --- | --- | --- |
| Luca | Telegram, Instagram and Messenger live; WhatsApp coming soon | $49/mo Creator to $999/mo Agency (500 to 17,000 replies) | Per reply, monthly | Coaches booking calls in DMs, auto-send on by default, review on any channel |
| respond.io | IG, WhatsApp, Telegram, Messenger, SMS | $79/mo Starter | Monthly active contacts | Small teams already running WhatsApp at volume |
| Chatwoot | IG, WhatsApp, Telegram, Messenger, email, web chat | Free plan (2 agents, 500 convos/mo); then $19/agent/mo | Per agent, or self-host | Operators who want to own the data |
| Trengo | IG, WhatsApp, Telegram, Messenger, email, voice | EUR 349/mo Boost (10 users, 500 convos) | Bundled users plus conversation packs | Teams of 10+ with a support function |
| Front | Email-first; social and WhatsApp on higher tiers | $25/seat/mo Starter (single channel); $65/seat/mo Pro | Per seat, annual | Agencies whose main channel is shared email |
| Missive | IG, WhatsApp, Messenger, email, SMS | $14/user/mo Starter (up to 5 users) | Per user | Two-to-five person teams on a budget |

**Choose by how you work.** Pick Chatwoot if you can run your own server and want no per-contact billing. Pick Missive or Front if email is your main channel and DMs are a side door. Pick respond.io or Trengo if you have a rota of agents and support tickets to close. Pick Luca if the job is booking sales calls out of DMs, you're one to three people, and you want each answer drafted the way you write. A coach with a 12-person support team should look at Chatwoot or Trengo first. For tools built for DM setting, see our [best AI DM setter](/blog/best-ai-dm-setter) roundup.

## What does each channel's API actually allow?

Each channel decides when you can reply and what it costs. These are platform rules, not tool rules, so every product above lives with the same limits.

| Channel | Who can start | Reply window | After the window | Setup needed |
| --- | --- | --- | --- | --- |
| Instagram DMs | Lead only | 24 hours from their last message | Human agent tag extends manual replies to 7 days | Professional account; one connected app |
| WhatsApp Business Platform | Lead, or you via template | 24-hour customer service window | Templates only, billed per message | Business number, Meta verification, template approval |
| Facebook Messenger | Lead only | 24 hours | Approved tags, including the 7-day human agent tag | Page admin access |
| Telegram | Lead must start the chat with your bot | None | No expiry; rate limits apply instead | Bot token from BotFather |

Three details catch people out. Meta's policy says an automated reply has to go out within 30 seconds of the lead's message, so a slow queue breaks a rule as well as a sale. On WhatsApp, Meta moved to per-message pricing on 1 July 2025: replies inside the service window are free for the first 1,000 a month per number, and templates outside it are billed each time. And Instagram allows one messaging app connected at a time. Add a second tool without unplugging the first, and messages stop arriving somewhere, with no warning.

If you're setting up WhatsApp fresh, read our [WhatsApp Business setup for coaches](/blog/whatsapp-business-setup-for-coaches) walkthrough and the [WhatsApp 24-hour window](/blog/whatsapp-24-hour-window) rules first. Messenger, meanwhile, is fading. Active use fell from **41.0% to 36.9%** of online adults in two years ([DataReportal, 2026](https://datareportal.com/reports/digital-2026-mid-year-global-update-report)).

## How to set up a unified inbox for coaches

You can build this in an afternoon, whether you run it yourself or hand it to Luca.

### Step 1: List the channels your leads actually use

Start with where DMs already come from. Often that's Instagram plus one or two of WhatsApp, Telegram, and Messenger. Don't add an app with no traffic. Our [best DM channel for coaches](/blog/best-dm-channel-for-coaches) guide breaks down the choice.

### Step 2: Connect each channel to one inbox

Instagram needs a professional account, WhatsApp a business number not already on the consumer app, Telegram a bot token, Messenger Page admin access. Do them one at a time. Test each with a message to yourself, so you know which one broke. The [Telegram bot for coaches](/blog/telegram-for-coaching-business) guide covers that one end to end.

### Step 3: Set routing rules

Sort by channel, by what the lead wants, or by stage: new leads to one view, follow-ups to another, booked calls to a third. This is where [Instagram DM automation for coaches](/blog/instagram-dm-automation-for-coaches) earns its keep.

### Step 4: Standardize your qualifying questions

Write one short set of questions and use it everywhere: their goal, their timing, and whether they're ready to spend. A lead should get the same thing in [WhatsApp for coaches](/blog/whatsapp-for-coaches) or [Telegram for coaching business](/blog/telegram-for-coaching-business).

### Step 5: Choose auto-send or review for each channel

With Luca, replies are drafted the way you write. Auto-send is on by default on every channel, and you can switch any channel to review.

### Step 6: Track every thread to a booked call

Give each thread a next step: answer, follow up, or book. Qualified leads go to your calendar. Quiet ones go into a follow-up run.

## How do you route and triage DMs in a unified inbox?

Route by priority first, channel second. Which app a message came from tells you almost nothing about how close it is to money. Sort by what the person wants instead: a "what's your price?" message outranks a "love your content" note, whichever app it landed in. Run three lanes: new leads waiting on a first answer, warm leads mid-thread, and quiet leads due a follow-up. Check the new-lead lane first, every time.

Once a second person touches the inbox, three things stop being optional. Assignment puts one name on each thread, so two people never reply to the same lead ninety seconds apart. Internal notes hold what the lead never sees, like "referred by Marta, quoted $2k in June." Routing rules decide who gets the next new lead. Make it stick, so whoever answers first keeps the thread through to the call. Asking the same questions everywhere matters here too, since [how AI qualifies leads in DMs](/blog/how-ai-qualifies-leads-in-dms) rests on it.

## A worked example: Dana's Tuesday

Dana coaches busy parents on strength training. She sells a 12-week block at $1,800 and runs Instagram, WhatsApp, and Telegram. This walkthrough is illustrative and anonymized.

At 9:02 a.m. a Story reply lands on Instagram: _"saw the Reel about training with a toddler on your hip, do you take people who can only do 20 mins?"_ Under the old set-up Dana saw it at lunch. With one inbox it's the top item in her new-lead lane. Dana approves every Instagram draft while she tunes the writing style, so Luca drafts an answer the way she writes: _"Twenty minutes is what most of my parents have. How many of those slots can you actually protect in a week?"_ Dana taps approve four minutes after the lead wrote in.

At 9:15 a WhatsApp message arrives from a referral. That lead messaged first, so Dana's service window is open until 9:15 tomorrow, and her answers count toward her 1,000 free service messages for the month.

At 12:40 a Telegram message asks about price. The inbox shows this person already exists: same phone number, same lead, who asked about her group program in July. The internal note reads "wanted January start." Dana quotes the price, references January, and the lead books that afternoon. Without one inbox, that July note sits in another app.

## What edge cases do most guides skip?

**The lead replies at 2 a.m.** Don't send at 2 a.m. from an account that is never awake then. Queue the draft for a time you might believably be awake, and judge how urgent it is by their clock, not yours. On WhatsApp the 24-hour clock is already running, so a 7 a.m. send sits well inside it.

**The lead is already a client.** Someone who already pays you shouldn't land in the new-lead lane, or get a qualifying script, for asking a program question. Tag them on first contact and send them to their own view.

**The same person messages on two channels under two names.** Instagram gives you a handle, WhatsApp gives you a phone number, and nothing ties the two together, so most tools create two contacts. Merge them when you notice, and let the phone number be the one that wins.

**The WhatsApp window closes overnight.** A lead who messaged at 4 p.m. and got no reply by 6 p.m. the next day is outside the customer service window. You now need a template Meta approved earlier. It costs money, and it reads stiffer.

**The lead is in another time zone.** Note it on the contact the first time it comes up, and set your calendar link to show times in their local clock. A booking page offering 3 a.m. loses the call you just earned.

## What breaks in a unified inbox, and how do you fix it?

| Symptom | Likely cause | Fix |
| --- | --- | --- |
| Instagram DMs stopped arriving | A second messaging app is connected, or the token expired | Disconnect every other tool, reconnect, reauthorize, then test from a second account |
| The same lead appears as two contacts | Nothing ties an IG handle to a phone number | Merge by hand, then add phone and email so future matching has a key |
| WhatsApp reply fails with a template error | The 24-hour service window closed | Send an approved utility template, or wait for the lead to write again |
| Two people answer the same thread | No assignment rule; both operators work the unassigned lane | Turn on sticky assignment so each thread gets one owner at first reply |
| Telegram bot goes quiet under load | Bot API rate limits, about one message per second per chat | Space out sends, drop broadcasts, check the log for 429 responses |

## What mistakes do coaches make with a unified inbox?

Most unified inbox mistakes come from connecting too much, too soon.

1. **Connecting every channel on day one.** An app with four DMs a month adds noise and one more thing to break. Connect the two that carry real weight, run them a fortnight, then add a third.
2. **Treating the inbox as a CRM.** These tools are poor at deal stages and client records. Keep the inbox for threads and push booked calls out to your calendar.
3. Skipping review while the writing style is still new. Switched on for a channel, review catches a bad reply while you're still tuning it. Read a hundred drafts and fix the ones that miss.
4. **Ignoring the WhatsApp window until the bill arrives.** Meta charges for each WhatsApp message, and templates outside the window are the dear ones. Same-day answers keep almost everything free.
5. **Buying on seat price alone.** Front's entry tier is single-channel and Missive's cheapest plan caps at five users. The headline price and the plan you actually need are rarely the same row.

## What should you measure once every channel is in one place?

The merged inbox is the first time these numbers mean anything, because you can finally compare apps on level terms.

- **Time to first reply, by channel.** Use the middle value, not the average, and count from the lead's message rather than from when you opened the app.
- **Unanswered threads older than 24 hours.** Should be zero most days. It's also the best early warning that a connection broke quietly.
- **Qualified-to-booked rate.** Of the leads who answer your questions, how many put something on the calendar.
- Draft approval rate, on any channel you're reviewing. How often you send an AI draft without touching it. A falling rate means the writing style needs another round of training.

Check them once a week. DM volume is lumpy enough that one day tells you nothing.

## The honest limit of a unified inbox for coaches

A unified inbox doesn't remove your judgment, and it shouldn't. Luca drafts and sorts replies the way you write. Auto-send is on by default on every channel, and you can switch any channel to review. It matters to people: **72% say they care whether they're talking to an AI agent**, across 16,585 surveyed ([Salesforce, 2026](https://www.salesforce.com/news/stories/state-of-the-ai-connected-customer/)). Review is how you stay the person in the thread on the calls that need it most.

A unified inbox for coaches fixes the app switching, not the replies, so you still read the threads that decide a sale.

Some threads you should take yourself, and no set of rules catches them all. A lead who mentions an injury, a death in the family, or a mental-health struggle needs you, not a draft. A refund ask, or a complaint about a past program, is yours from the first message. So is any thread where someone seems to be talking themselves into buying something they can't afford.

The merged screen also can't fix a channel you shouldn't be on. If Telegram brings you two tyre-kickers a month, connecting it just moves the noise closer. A unified inbox makes a good pipeline faster, and a thin one easier to see.

## FAQ

### What is a unified inbox for coaches?

A unified inbox for coaches is one screen that merges DMs from several apps into a single queue. Luca puts Telegram, Instagram and Messenger in one inbox (WhatsApp is coming soon), drafts replies the way you write, and moves leads toward a booked call. Auto-send is on by default on every channel, and you can switch any channel to review.

### Which channels can a unified inbox connect?

Most unified inboxes for coaches connect Instagram DMs, WhatsApp Business, Telegram, and Messenger. Luca puts Telegram, Instagram and Messenger in one inbox today, and WhatsApp is coming soon. You link each app once, and new messages from any of them land in the same queue. Leads stop slipping through because they came in on an app you weren't watching.

### How much does a unified inbox cost?

Published August 2026 entry prices sit far apart: Chatwoot starts free for two agents, Missive from $14 per user per month, respond.io from $79 per month, Luca from $49 per month, and Trengo from EUR 349 per month. The way they bill differs too, so weigh per-seat against per-contact pricing before you commit. Every self-serve Luca plan comes with a 7-day free trial (card required).

### Do I lose control if the AI handles my inbox?

No. Luca drafts replies the way you write, and you keep control: auto-send is on by default on every channel, and you can switch any channel to review. The AI does the drafting, sorting, and follow-up work. You keep the final say on tone, price, and fit.

### How long does it take to set up a unified inbox?

You can set up a unified inbox in an afternoon. You connect each channel once, write one set of qualifying questions, and set your routing rules. After that, new DMs from every channel flow into a single queue automatically, and you can reply, review, and book from one place.

### Why does response speed matter with a unified inbox?

Speed is the whole point of one screen. When every DM lands in one queue, you see new leads right away and reply before they cool off. No more finding them hours later in an app you forgot to check.
