What it is

When a call goes unanswered, the caller automatically receives a text (or WhatsApp message) within seconds, so they are not left wondering whether to try the next business. A person or an AI assistant then continues the conversation by message.

When to send it

  • Calls that ring out or go to voicemail during opening hours.
  • All calls outside opening hours.
  • Not for calls from numbers you have blocked, internal numbers, or very short accidental calls if your system can detect them.

Rules that keep it helpful

  1. Send fast: within a minute, or it feels random.
  2. Say who you are in the first words.
  3. Ask one simple question, or give one link. Not both plus a menu.
  4. Stop if they call back or reply, and alert a person.
  5. Do not add marketing. It is a reply to someone who contacted you, not a promotion.
  6. Respect opt-outs and keep a record.

Setup options

Option Notes
Your phone system's built-in feature Simplest if available
Call tracking or VoIP provider with automation Ties calls to sources and the CRM
CRM with telephony integration Best for logging and follow-up
