Missive

What is Missive?

Missive is a team email and messaging platform that turns a shared inbox into a collaborative workspace. Multiple teammates can draft a reply together, leave internal comments on a thread, and assign conversations as tasks — all without the customer seeing any of it. It supports email alongside SMS, WhatsApp, live chat, and social media DMs in a single interface.

Who is it for?

Missive is a strong fit for small and mid-sized teams that handle a high volume of customer communication across multiple channels and want to coordinate responses internally without forwarding emails or using a separate chat tool. Support teams, agencies, and operations teams that live in email are its core audience.

Strengths

• Real-time co-authoring — multiple users can write and edit a draft reply simultaneously before it's sent.
• Internal comments — leave private notes on any conversation thread, visible only to teammates.
• Omnichannel inbox — email, SMS, WhatsApp, live chat, and social DMs in one unified view.
• Task and assignment system — conversations can be assigned to teammates with statuses and due dates.
• Usage-based AI pricing — AI features are billed through your own AI provider account rather than a fixed monthly surcharge.

What to consider

• Missive is primarily an inbox tool, not a full CRM; contact history and deal tracking are limited.
• The free plan is capped at 3 users with restricted history — most teams will need a paid tier quickly.
• Integration depth with external CRMs requires manual configuration or Zapier.

Bottom line

Missive is one of the cleanest collaborative inbox tools available, especially for teams that struggle to coordinate email replies without stepping on each other. It doesn't replace a CRM, but as the communications layer in front of one, it's excellent.
