How it works in DoubleAM?

  1. Connect with your WhatsApp Business App or Setup with a New WhatsApp Number

  1. Your WhatsApp runs in two places:

    • On your phone (normal WhatsApp/Business app)

    • Inside HighLevel (for automations, workflows, bulk sends, AI employees)

  1. Conversations sync into your CRM inbox and trigger workflows.

  1. Campaigns and AI employee messages send from the CRM without affecting your phone’s use.
