Where each one falls short

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

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.

Whereby

  • No breakout rooms, polls, or whiteboard tools
  • Hard cap of 200 participants and performance drops with groups of 12+
  • No phone dial-in option for participants without internet
  • Occasional connectivity issues and laggy screen sharing reported
