Key capabilities include:

• Shared inboxes with internal threads for behind-the-scenes discussions, collaborative drafting, and clean external replies
• Omnichannel messaging across email, SMS, WhatsApp, Facebook, and Missive Live Chat, plus unified inbox views
• Rules, automations, and AI-assisted writing to handle repetitive triage and help draft or edit messages
• Integrations, analytics, and developer access including integrations such as ChatGPT, Pipedrive, and Trello, plus reporting and an API

Pricing: Freemium. Free plan includes 15 days history, 2 personal accounts per user, 2 shared email accounts, and up to 3 users. Paid plans (billed per user/month yearly) are Starter $14, Productive $24, and Business $36 (monthly pricing is higher). A 30-day free trial is available with no credit card required.
