Missive

Missive is the email client teams run their business from: one shared inbox for email, WhatsApp, SMS, and the internal chat around them. Connecting Missive lets Claude search conversations across every channel in one pass, summarize threads and labels, look up contacts, calendars, and canned responses, and stage drafts with your team's signature applied. Ask who's still waiting on a reply, which customer emails are urgent this week, or what topics keep coming up in support. Claude drafts; your team reviews. Composing and delivering are separate steps, so nothing reaches a customer until someone approves it, and you can disable sending entirely for a draft-only setup.
