How to choose
Match the tool to your primary channel and volume: WhatsApp-heavy teams should prioritize AxChat, Pell, or Telinfy while iMessage needs point to Comms. Check how much autonomy the AI actually has versus simple automation, especially for agent workflows like those in Claude Opus 5 or Buzz. Watch compliance and delivery reliability when replacing OTPs or scaling RCS, and avoid tools that lock you into one channel without clear export options.
