Where each one falls short

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

Close

  • Hidden costs beyond subscription: calling charges (~$0.02/minute), SMS usage fees, phone numbers ($1-5/month), AI call assistant ($50/month + $0.02/min transcription)
  • No built-in lead lists, company intelligence, or contact enrichment; must source leads separately
  • Limited marketing automation compared to competitors like HubSpot; lacks lead scoring and nurturing campaigns
  • Calling cost at scale can double effective monthly cost for high-volume SDR teams making 50+ calls per day
  • Limited customization of data model compared to Salesforce; cannot create fully custom objects or complex relationships

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.
