What's the best omnichannel inbox in 2026?

Crisp is a French company, and it does the omnichannel inbox job better than anyone for a small team. Website chat, email, WhatsApp, Instagram, Messenger and SMS land in the same list. Every conversation gets an owner, internal notes and the customer's history, whatever channel it came from.

The pricing model is what sets it apart. You don't pay per person. You pay a flat fee per workspace with seats included. Essentials costs $95 a month for 10 seats, so $9.50 per person. Ten people on Front's omnichannel plan cost $650 a month.

Watch the tiers, though. Free is chat only, and Mini at $45 adds shared email but not WhatsApp or Instagram. The real omnichannel inbox starts at Essentials. Plus, at $295, goes to 20 seats and unlocks 100+ integrations.

The catch: it isn't a full ticketing system. SLAs and reporting stay light, and some customers complain about accounts suspended without warning. The tiers also jump: your 11th agent takes the bill from $95 to $295, unless you add $10 seats instead.

Tip: at 11 or 12 people, buy one or two extra seats on Essentials rather than moving to Plus. You pay $105 or $115 instead of $295.

Trengo comes from the Netherlands and is built around one idea: WhatsApp, email, Instagram, Messenger, website chat and voice in a single team inbox. Conversations get assigned by rules, teammates mention each other in internal notes, and WhatsApp runs through Meta's official Business Platform.

Pricing is a team bundle, listed in euros. Boost costs €299 a month billed annually (€349 monthly) for 10 users and 500 conversations a month. Pro, at €499 (€599), gives you 20 users and 1,500 conversations. An extra user is €25 on Boost and €40 on Pro.

The trap is the conversation quota. Past your bundle, every block of 100 conversations costs €15. A WhatsApp campaign that gets 400 extra replies adds €60 that month. HelpMate, the AI agent, adds €0.25 per conversation it handles.

The catch: users rate the mobile app poorly (slow, rough on iPad) and reporting stays basic. For a team of 3, €299 a month is three times Crisp Essentials.

Tip: Trengo says the first 1,000 WhatsApp service messages per number each month carry no Meta fee. Reply fast to customers who message you instead of chasing them with paid templates.

Front feels like email, only shared. Teammates see who's replying, comment on a message without forwarding it and draft together. It's the most pleasant tool here for teams that write a lot, and its routing rules go deep.

Read the plans carefully. Starter, at $25 per seat per month billed annually, supports one channel type only: email, or chat, or SMS. That's not an omnichannel inbox. You need Professional, at $65 per seat, to bring email, SMS and social together. Ten people run $650 a month.

WhatsApp isn't included either. The native connector is an add-on on Professional and Enterprise: you pay Meta's fees plus a 20% admin fee charged by Front. Copilot costs $20 per seat per month, and Autopilot starts at $0.05 per conversation.

The catch: cost grows with every hire, and the mobile app is poorly rated (3.3 on iPhone, 2.6 on Android in the US), with forced logouts. One customer reports a forced 40% price increase after four years.

Tip: start the 14-day trial on Professional (no credit card) and connect your real WhatsApp number on day one, so you see actual Meta fees.

respond.io was built for messaging apps first and email second. WhatsApp, Instagram, Messenger, Telegram, site chat and email land in a team inbox, but the tool goes further: it tracks each contact's lifecycle stage (lead, customer, follow-up) and fires workflows.

Price depends on the tier and on monthly active contacts. Starter, at $79 a month billed annually, includes 5 users but no workflows, no broadcasts and no AI agents. That's a real limit, and most teams land on Growth: $159 a month billed annually ($199 monthly) with 10 users.

Watch the active-contact meter. Growth includes 1,000 active contacts a month, then every 100 extra cost $12. A campaign that gets 2,000 more people talking adds about $120 that month. Meta's WhatsApp fees are billed on top.

The catch: setup takes time, and reviewers mention a real learning curve. One finds it pricey for a small team since AI isn't on the entry tier.

Tip: the 7-day trial gives Growth access for 5 users and 1,000 contacts. Map your workflows before you start it, or you'll burn the week on setup.

Help Scout keeps the look of an email inbox. Your customer gets a normal email, no ticket number. Your team sees who's on what, leaves internal notes and never answers the same message twice.

The free plan is the most generous here: 5 users, one inbox and a help center, capped at 100 contacts a month. Standard, at $25 per user, adds website chat, SMS, WhatsApp, Instagram and Messenger in the same inbox, with two inboxes included. Plus, at $45, gives you five.

AI drafting and summaries are included on paid plans. The AI agent costs $0.75 per resolved request, with a monthly cap you set yourself and three months free.

The catch is depth. No native phone, reporting that feels thin as the team grows, and a per-user price that adds up. Ten people on Standard run $250 a month.

Tip: an extra inbox costs $10 a month. Route contact@, billing@ and support into one inbox and sort with tags.

Missive is a collaborative email client from Quebec. It pulls your personal and shared addresses, SMS, WhatsApp, Messenger and Instagram into one place, with an internal chat thread next to every message. You write replies together, live, like a shared doc.

It's the cheapest option here for a small team. Starter costs $14 per user per month billed annually but caps at 5 people. Productive, at $24, is the tier that matters: up to 50 users, 1,000 rules and the WhatsApp, Messenger and Instagram integrations. Five people run $120 a month.

The free trial runs 30 days on Productive, no card needed. That's the longest trial in this ranking.

The catch: Missive has no built-in website chat, and it isn't a help desk. No help center, no SLAs, simple reporting. Users also flag loud default notifications and a thinner mobile app, and everyone has to move into the Missive app.

Tip: tune each teammate's notifications on day one, or the team will mute everything within a week.

Gorgias is a help desk built for Shopify. From any conversation, your agent sees the order, edits it or refunds it without opening the store admin. When you handle hundreds of requests, those saved clicks matter more than the sticker price.

It bills per ticket, not per seat. And a ticket is anything that comes in: a chat, an email, an Instagram DM, a call. Starter at $10 a month includes chat but only 50 tickets and 3 agents. Basic gives you 300 tickets and unlimited agents for $60. Pro is $360 for 2,000 tickets, Advanced $900 for 5,000.

The AI agent is billed on top of the ticket: $1 per automated interaction. Past your quota, extra tickets cost from $36 to $40 per 100 depending on the plan.

The catch: merchants mention spam calls counted as tickets, an unstable mobile app and a heavy bill during the holiday peak. Outside Shopify, most of its edge disappears.

Tip: look at your ticket count for November and December last year, not your average month, before you choose a tier.

Zendesk is the standard for large support teams. Every email, chat, WhatsApp or Instagram message becomes a ticket in a shared queue, with rules that assign it, follow up and measure it. Few tools handle hundreds of agents this well.

The entry price is misleading. Support Team, at $19 per agent, is email only. WhatsApp, Instagram and Messenger need a Suite plan: Suite Team at $55 per agent billed annually ($69 monthly). Ten agents cost $550 a month, nearly six times Crisp Essentials.

Suite Professional, at $115, adds skills-based routing and custom reports. AI is billed separately, per outcome.

The catch is ease of use. Small teams find the interface heavy, and rule setup often needs an admin. Instagram requires a business or creator account linked to a Facebook page.

Tip: if you already run Support Team, price the social messaging add-on against an upgrade to Suite Team. The Suite often costs the same and includes chat.
