The short version

  • Only OneSignal has a free tier, so it costs nothing to try first.
  • Each has a real cost: OneSignal free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026); 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.

Where each one falls short

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

OneSignal

  • Free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
  • Professional and Enterprise plans require custom annual contracts with no published rate, per onesignal.com; SMS/RCS messaging and dedicated IPs are gated behind the Professional tier

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.
