The team boundary matters
Missive is built for collaborative customer conversations. Its feature overview documents shared inboxes, assignments, tasks, rules, integrations and customer channels. Otto supports shared mailboxes and, where enabled, business-hour response targets for assigned threads. Otto's private assistant messaging is a way to control your own workspace; it is not a replacement for Missive's WhatsApp, SMS or social customer inbox.
Plans and fit
Missive's pricing lists Starter at $14, Productive at $24 and Business at $36 per user per month when billed yearly, plus a 30-day trial, as checked in September 2026. It also advertises custom integrations, AI allowances and bring-your-own-key options. Those are meaningful strengths if your team needs a custom customer operation.
Choose Missive for a shared service queue with multiple inbound channels. Choose Otto when the center of the day is your own mail, calendar, tasks and reviewable assistant work, with shared-mailbox coordination where your plan supports it.
Questions, answered
Is Otto's WhatsApp assistant the same as Missive's customer inbox?
No. Otto's private channels (Telegram, Slack and Discord today; WhatsApp is coming soon) let you ask your own assistant to work and receive your brief. Missive handles customer conversations arriving through its supported channels.
Can Otto track team response times?
Eligible teams can enable business-hour response targets for assigned shared-mailbox threads where the feature has rolled out.
