About Missive + AI
Missive is a collaborative team inbox that unifies email, SMS, WhatsApp, Instagram, Messenger, and live chat into a single shared conversation view. Instead of forwarding emails or sharing passwords, your whole team works in shared inboxes, comments internally, co-writes drafts in real time, and turns messages into trackable tasks. It's built for customer-facing teams that live in email—support, sales, agencies—and need a centralized hub where nothing slips through the cracks. The built-in AI assistant works right where you do. Click the AI icon on any message to summarize, translate, or generate a reply. In drafts, select text to rewrite, fix grammar, or change tone. You can also build AI Rules to auto-summarize long threads, label conversations by topic, extract action items as tasks, or draft replies before a human ever opens the message. The AI picker now includes Sonnet 5 and Opus 4.8 alongside OpenAI's GPT-5 mini, GPT-5, and GPT-4o mini, so you can choose the model that fits the task. Missive follows a bring-your-own-key model: connect your own OpenAI API key and pay OpenAI directly for usage—no per-seat AI fees. Custom prompts use variables like [message], [selection], and [documentation] (your canned responses), so AI output stays grounded in your actual business knowledge. Data submitted through the API is not used to train OpenAI models. It's more than email. Missive handles tasks with due dates and calendar view, canned responses, team spaces, internal chat, and guest access. Recent updates add Quo SMS accounts, draggable dialogs, and a collapsible sidebar. Pricing starts at $14/user/month (billed yearly) for Starter, with a free plan for up to 5 users. Compared to Front or Help Scout, Missive gives you AI without a per-seat add-on and a more affordable entry point.
Behind the Verdict
Missive stands out by pairing a genuinely collaborative inbox with an AI assistant that doesn't require a separate per-seat subscription. The bring-your-own-key approach means you pay only for actual usage, which is a major plus if you already have an OpenAI API key. The integration supports GPT-5 mini, GPT-5, and GPT-4o mini, with newer Anthropic models like Sonnet 5 and Opus 4.8 also available, so you can pick the model that fits each task. The AI assistant is deeply integrated: you can summarize messages, translate, rewrite drafts, and generate full replies. The ability to create custom prompts using variables like [message], [selection], and [documentation] is a differentiator, keeping outputs grounded in your canned responses. AI Rules let you automate labeling, summarization, and task extraction, which is a real time-saver for busy teams. Collaboration features are strong: internal threads, co-drafting, task assignment with due dates, and guest access make it easy to work as a team. The recent addition of Quo SMS (formerly OpenPhone) expands its multichannel capabilities. However, the free plan is capped at 5 users, and advanced features like analytics and API access require the Productive tier. If you need SAML SSO and IP restrictions, you'll have to pay for Business. The main friction is the bring-your-own-key setup: you need an OpenAI API account, not a ChatGPT subscription, and must manage billing with OpenAI. This might be a hurdle for non-technical users. But for teams that already use OpenAI, it's a cost-effective way to get AI in your inbox without paying per seat. Overall, Missive is a strong choice for support, sales, and agency teams that need a shared inbox with built-in AI. It's not ideal for individuals seeking a lightweight personal email client, or for organizations that need on-prem deployment.
