Where each one falls short

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

Five9

  • A 50 seat minimum applies to the published rates, so the entry cost on the $119 Digital plan is $5,950 a month
  • Prices are per concurrent user rather than per named agent, which changes what a seat means when shifts overlap
  • Voice is excluded from the Digital plan and requires a quote
  • Usage based charges apply on top of the per seat rate
  • Three of the five tiers publish no price at all

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.
