The problem

Most AI email tools are copy-paste exercises

They can write a decent email, if you feed them every piece of context yourself. What if the AI could go get the context on its own? What if it can truly be of assistance?

Capability & Features

AI with real access to your inbox

Search your emails

Ask “what did we quote this client in January?” The assistant finds it, even if it’s buried in an attachment.

Check your calendar

Need to suggest meeting times? The assistant reads your calendar, checks for conflicts, and proposes meeting times.

Draft replies in your team's voice

Set your tone and style once. Every AI draft follows them on email, SMS and WhatsApp. Nothing is sent until you approve.

Use what your team already built

Look up a contact, find the right canned response, or label conversations straight from the sidebar.

Automate with AI rules

AI rules read each email and act on it. Is there a deadline? Create a task. Is the customer upset? Alert a manager.

“The ability to put in MCP servers that I use, like Granola and Affinity, has made a pretty dramatic impact on my work. The quality of the AI responses feels like they've gotten a lot better, particularly the ability to look up calendar and bring in insights there.”

Go beyond email with MCP

Your tools, inside Missive

Ask the assistant to look up a customer's billing history in Stripe, create a Linear issue from a bug report, or pull context from a Notion doc. It all happens in the sidebar, in the same conversation.

Missive MCP server: bring your inbox to your AI

Ask Claude or ChatGPT to “go through last quarter’s customer conversations and turn the top feature requests into a report.” Unlock years of customer knowledge sitting in your inbox.
