Missive

Are you double sending emails? Not knowing who's responding to what, or whether they've responded at all? Losing the thread when the person who owns it is out? What if your business could manage all your email accounts, including its shared inboxes like support@, sales@, info@, and accounting@, along with SMS, WhatsApp, Messenger, and Instagram—all in one place? Missive is inbox collaboration for teams that run on email. Every conversation gets an owner, so nobody replies twice and nothing sits unread for a week. Teammates discuss a thread in private comments right beside it instead of forwarding it around, and when someone's away, whoever picks it up gets the full history. Missive's AI assistant works inside the inbox. It reads a thread and drafts a reply in your voice, searches your email, contacts and calendar, and reads attachments. Through MCP it pulls context from tools like ClickUp, Todoist and Stripe—and the reverse, letting Claude, ChatGPT or Cursor act on your conversations, contacts and drafts from outside Missive. Bring your own Claude, OpenAI or Gemini key, or use Missive AI credits. You approve before anything sends. Used by over 6000 businesses, including accounting firms, manufacturers, property management companies, travel agencies, legal practices, and logistics teams. -- Key features • Team Inboxes: Shared addresses the whole team works from, with assignment so every conversation has a clear owner and coverage when someone's out. • Internal comments and @mentions: Discuss a thread in a private sidebar next to the actual email. The customer never sees it. • AI assistant: Drafts replies in your voice, searches your inbox, contacts and calendar, and reads attachments. Labels, events and sends happen only after you approve. • MCP in both directions: Missive AI connects out to tools like ClickUp, Todoist and Stripe, and Missive's MCP server lets Claude, ChatGPT or Cursor work on your inbox from outside. • Automated Workflows: Create customizable rules to automate repetitive tasks and use AI to get even more efficiency. Popular use cases include auto-categorization of emails, auto-follow-up emails, automatic forwarding of receipts, and out-of-office auto-responses. • Canned responses: Save time with pre-written replies to customer inquiries, sales pitches, or to include that PDF you always need to attach when signing up a new client. • Integrations: Pipedrive, HubSpot, Shopify, Airtable, ClickUp, Asana, Dialpad, Twilio, Aircall, Zapier, and a REST API for building your own.
