The short version

  • Only Missive has a free tier, so it costs nothing to try first.
  • Each has a real cost: Missive each plan caps users rather than only pricing them, at 5 on Starter and 50 on Productive; Sinch much of the portfolio arrived through acquisition, so a customer buying messaging and email should check how consistent the consoles, APIs and support processes actually are across those specific products.
  • They diverge on capability: Missive covers Shared inbox, Sinch covers Published per-country rate card.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

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

Sinch

  • Much of the portfolio arrived through acquisition, so a customer buying messaging and email should check how consistent the consoles, APIs and support processes actually are across those specific products.
  • Product overlap from acquisitions means the right Sinch product for a use case is not always obvious and sales guidance varies.
  • Integrating acquired businesses is a continuing programme, so account handling and support contacts can change under a customer mid-contract.
  • The published rate card is a list price, so organisations at volume still negotiate and small senders pay the advertised rate without leverage.
  • US A2P messaging carries 10DLC registration fees and per-segment carrier surcharges on top of the published rates, as it does with every provider.
