When a contact does not answer, the AI can leave a voicemail on your behalf. Configuring an effective voicemail message increases callback rates and keeps your brand consistent.

Enabling Voicemails

Leave Voicemail is on by default, and Atllas auto-populates the voicemail message field with one generated from your call script and call details. You don’t need to write anything to start — the campaign is ready to leave voicemails the moment you launch it. If you don’t want voicemails at all, toggle Leave Voicemail off. The AI will hang up as soon as voicemail is detected.

Voicemail Message

You have two ways to set what gets read:

Use the Auto-Generated Message

The default voicemail is already filled in for you. Review it on the Voicemail step — edit anything you want to change, or accept it as-is.

Regenerate

If the auto-generated text doesn’t fit, click Generate with AI to produce a new draft. The new draft replaces what was in the field. Repeat until you’re happy with the message.

Write Your Own

Replace the field’s contents with whatever you’d like the AI to leave. Whatever’s in the field is read verbatim on every voicemail — the voicemail message does not support personalisation tokens, so the same message is left for every contact.

Tips for Effective Voicemails

  • Keep it under 30 seconds — long voicemails are rarely heard in full
  • State your name, company, and one clear reason for calling
  • Include a callback number or next step
  • Avoid scripted-sounding language; conversational works better
