Missive + AI
Missive + AI folds GPT-powered summarize, translate, and reply drafting into a shared team inbox for email, SMS, WhatsApp, and chat.
If your team already lives in a shared inbox and is willing to run an OpenAI API key, Missive folds the two together without charging an AI add-on per seat — Starter is $14 per user/month billed yearly, Productive $24, Business $36. The attachment reading and the MCP server now shipping on Productive and above (or a trial) make it more useful than the version we reviewed before. The honest trade-off: BYOK shifts friction from billing to configuration, and SSO only arrives at Business. Compare against Front and Help Scout before committing.

Skip Missive if nobody on your team will own an OpenAI API key with pay-as-you-go billing, since a ChatGPT Plus subscription will not work and quality depends on your own prompt tuning.
You pay OpenAI separately on top of your Missive seat — the API usage is billed pay-as-you-go to your own platform account, not included in the subscription.
Missive sits in the mid-market shared-inbox band: Starter at $14 per user/month billed yearly undercuts Front and Help Scout's comparable tiers, while Business at $36 per user/month billed yearly is where security features land. A 5-person team gets real collaboration plus BYOK AI for far less than per-seat AI add-ons, but the AI token bill goes to your own OpenAI account.

About Missive + AI
Missive is a collaborative team inbox that pulls email, SMS, WhatsApp, Messenger, Instagram, and live chat into one shared conversation view. Support, sales, and agency teams use it so they stop forwarding messages and sharing passwords: conversations carry internal threads, @mentions, assignments, tasks with due dates, and canned responses you share as team snippets. The AI layer is bring-your-own-key. You connect an OpenAI platform account with pay-as-you-go billing (not a ChatGPT Plus subscription — Missive states plainly that a $20/month ChatGPT Plus plan will not work), or you use Missive AI credits. The integration supports GPT-5 mini for fast, cost-effective work, GPT-5 for complex reasoning and detailed analysis, and GPT-4o mini as the previous generation. On pricing, Missive lists AI providers as multi-provider: Anthropic, OpenAI, and Gemini. You click the AI icon on any message to summarize, translate, or generate a reply, or select text in a draft to rewrite, fix grammar, or shift tone. AI Rules push that work upstream — auto-summarize long threads, auto-label conversations by topic, extract action items as tasks, and pre-draft replies before anyone opens the inbox. Custom prompts use variables like [message], [selection], and [documentation], the last grounding generated replies in your actual canned responses rather than generic filler. Since our last look, the assistant reads attachments (PDFs, images, documents) as context, composes brand-new messages with recipients set, and searches your calendar by keyword. The MCP server left beta in September 2026 — it now runs on Productive and above, or on a trial — so external AI apps like Claude, ChatGPT, or Cursor can connect and act on conversations, contacts, calendar, and drafts. Starter runs $14 per user per month billed yearly, and there is a free plan capped at 5 users.
Behind the Verdict
Missive's real differentiator is not the AI — it is the collaboration model underneath. Conversations carry internal threads, @mentions, assignments, and co-written drafts, and the same view holds email, SMS, WhatsApp, Messenger, Instagram, and live chat. That means the AI is summarizing and drafting inside a thread your whole team already shares, which is a meaningfully different context than an AI bolted onto a personal inbox. On the AI itself, the important architectural fact is choice. Missive lists multi-provider support (Anthropic, OpenAI, and Gemini), with either Missive AI credits or bring-your-own-key. The OpenAI integration names GPT-5 mini, GPT-5, and GPT-4o mini. Setup is the friction point: you need an OpenAI platform account with API access and pay-as-you-go billing, and Missive is explicit that a ChatGPT Plus subscription will not work. Each user can add their own key, and data sent through the API is not used to train OpenAI models. If nobody on your team wants to own an API key, this is the wrong shape of product for you. Where it earns its keep is automation. AI Rules let you auto-summarize long threads, auto-label by topic, extract action items into tasks, and pre-draft replies for common inquiries before a human opens the message. Custom prompts with [message], [selection], and [documentation] variables let you ground replies in your actual canned responses. The assistant also reads attachments (PDFs, images, documents), composes new messages with recipients set, and searches your calendar by keyword. The MCP server, out of beta and available on Productive and above or on a trial, lets Claude, ChatGPT, or Cursor act on conversations, contacts, calendar, and drafts, with OAuth scopes for custom servers. The weaknesses are structural rather than cosmetic. Rules are capped at 1,000 per workspace, which high-volume teams can exhaust. Starter caps at 5 users and gates external-tool integrations to Productive, so you outgrow the cheap tier quickly. SAML SSO and IP restrictions are Business-only at $36 per user/month billed yearly, which is a real jump for a security-conscious 20-person team. And the AI is only as good as your key setup and prompt tuning — budget an afternoon. Fit: support, sales, and agency teams that already run a shared inbox and are comfortable with a pay-as-you-go model account. Not fit: on-premise requirements, solo users wanting a personal mail client, or buyers who want AI bundled with no model account involved.

Real-world workflow fit
Concrete scenarios for the personas Missive + AI actually fits — and what changes day-one when you adopt it.
Email, WhatsApp, and Instagram land in one shared inbox. AI Rules auto-summarize long threads, label them by topic, and pre-draft replies for common inquiries; the assistant reads a PDF invoice a customer attached.
Outcome: Agents open the inbox to pre-labeled, pre-summarized conversations and edit a draft rather than starting cold, cutting first-response time without adding a per-seat AI add-on.
Conversations for each client live in team spaces. Drafts are co-written with colleagues, the assistant translates a French client's email, and tasks with due dates are extracted from the thread.
Outcome: Client threads stay with the team instead of in one person's mailbox, and action items become assigned tasks rather than getting lost in a long reply chain.
The MCP server is enabled on Productive (or during a trial) with a custom server configured with OAuth scopes, letting an external AI app read and act on conversations, contacts, calendar, and drafts.
Outcome: The inbox becomes a tool the AI agent can operate on directly, so routine lookups and draft creation happen outside the Missive UI.
Use Cases
- Summarize a long email thread to grasp a customer issue before replying
- Translate incoming messages into your team's preferred language
- Generate a draft reply grounded in your canned responses via the [documentation] variable
- Create AI rules that auto-label conversations by topic before anyone opens the inbox
- Rewrite selected draft text to change tone or fix grammar
- Extract action items from conversations into assigned tasks automatically
- Have the assistant read a PDF, image, or document attachment and summarize the key points
- Compose a new message from scratch across email, SMS, and WhatsApp with recipients set
Models Under the Hood
as of 2026-09-23
Limitations
- Users need their own OpenAI API account with pay-as-you-go billing; Missive states that a ChatGPT Plus subscription will not work.
- Starter is capped at 5 users, and external-tool integrations and API/MCP access require Productive.
- SAML SSO and IP restrictions are Business-only.
- Rules are capped at 1,000 per workspace.
- You also need an afternoon for key setup and prompt tuning, since output quality depends on your prompts and canned responses.

Where the pricing makes sense
The company stage and team size where Missive + AI's pricing actually pencils out — and where peers do it cheaper.
Missive sits in the mid-market shared-inbox band: Starter at $14 per user/month billed yearly undercuts Front and Help Scout's comparable tiers, while Business at $36 per user/month billed yearly is where security features land. A 5-person team gets real collaboration plus BYOK AI for far less than per-seat AI add-ons, but the AI token bill goes to your own OpenAI account.
Setup time & first value
How long it actually takes to get something useful out of Missive + AI — broken out by persona, not the marketing-page minute.
Plan an afternoon: create an OpenAI platform account, add billing, generate an API key, and paste it into the AI Assistant or Settings > Integrations. Each user can add their own key. Then tune custom prompts and AI Rules before the automation is genuinely useful. Teams on a trial can enable the MCP server right away; otherwise it needs Productive or above.
Switching to or from Missive + AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Front: Missive publishes a migration guide covering the move from Front in its docs.
- →From Outlook: a dedicated docs guide walks through migrating to Missive from Outlook.
- →From a shared Gmail or Office 365 mailbox: connect the account directly and import unlimited email history on the yearly plan.
- ↗To a personal mail client: export or reconnect your underlying IMAP/Gmail/Office 365 account, since Missive is built around the account rather than a proprietary store.

Featured Head-to-Head Comparisons
Missive Ai vs B Rokratt
Bürokratt and Missive + AI serve entirely different needs. Pick Bürokratt if you're an Estonian resident needing free, AI-powered access to government services. Choose Missive + AI if you're a business team wanting to collaborate on email and automate workflows with AI — it’s paid but offers powerful integrations and recent UX improvements like draggable dialogs and collapsible sidebars.
Missive Ai vs Hi Marley
Missive + AI is the right choice for customer-facing teams that need a unified inbox with powerful AI collaboration—especially if you want to bring your own AI API key to avoid per-user fees. Hi Marley is purpose-built for P&C insurers, offering SMS-first claims workflows, deep Guidewire integration, and AI Coaching for sentiment, but it's not a general-purpose support platform. Choose Missive for broad teamwork and chat; choose Hi Marley for insurance-specific claims automation.
Missive Ai vs Chatlyn
For hospitality businesses needing a purpose-built AI omnichannel hub that integrates directly with PMS and automates guest journeys, Chatlyn is the clear winner. General teams focused on email collaboration with flexible AI can choose Missive + AI, especially if they want to bring their own API keys and have a richer task management layer. Neither tool replaces the other — pick by industry and core workflow.
