category

Business messaging and iMessage API

market profile

  • text: Sales teams want a more conversational channel for lead follow-up within their existing CRM.
  • text: Developers building messaging agents need an API, phone lines, webhooks and fallback channels.

personas

  • title: Head of sales or revenue operations
    pains:
    • Prospects ignore follow-ups sent through crowded channels
    • Reps need a shared view of conversations and CRM-triggered workflows
  • title: Sales development representative
    pains:
    • Manual follow-up takes time across a large lead queue
    • Generic messages can feel impersonal and reduce engagement
  • title: Developer building a messaging agent
    pains:
    • Needs to provision a line and connect inbound messages to an application
    • Must handle non-iMessage recipients, callbacks and media

icp

  • text: Sales-led businesses with inbound leads, CRM-based follow-up and multiple reps needing personalized conversations.
  • text: Software teams embedding inbound messaging and AI agents in customer-facing applications.
  • text: Larger or regulated organizations evaluating SOC 2, HIPAA plans and managed deployments.

message pillars

  • text: Connect sales follow-up to existing systems.
  • text: Combine team messaging with automated follow-up.
  • text: Developers can start in a sandbox.

objections

  • objection: Can we test without committing to dedicated lines?
    response: Use the free sandbox with verified contacts; outbound messages and webhooks require a different plan.
  • objection: How do we control compliance and consent?
    response: Review opt-in and opt-out procedures with counsel and confirm the intended workflow before sending.
  • objection: We need outbound, not just inbound agents.
    response: Confirm a custom Enterprise quote because the published AI Agent plan is inbound-first.
