Where each one falls short

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

Hiver

  • Hiver tiers as captured 28 December 2023: Lite at $15/user/month capped at 2 shared inboxes (up to 10 users each), Pro at $39/user/month capped at 5 shared inboxes and 50 shared labels, Elite at $59/user/month, all annual pricing with higher month-to-month rates of $19/$49/$69

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.
