  • They diverge on capability: Kayako covers Unified inbox, Missive covers Shared inbox.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kayako

  • The AI agent is billed at $1 per resolved ticket, so support cost scales with ticket volume rather than being a fixed subscription
  • A resolution counts when the AI solves the issue without human involvement, so the definition of a billable event is set by the vendor's own system
  • No per agent monthly price is published for the full Kayako One platform
  • Full platform pricing requires talking to an expert

Missive

  • Each plan caps users rather than only pricing them, at 5 on Starter and 50 on Productive
  • Integrations, automation rules and API access all require the Productive plan at $24 per user per month
  • Rules are capped at 1,000 per workspace even on the paid tiers
  • SAML SSO and IP restriction are Business only at $36 per user per month
  • AI features need either Missive AI credits or a bring your own key arrangement rather than being included
