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.

Turn on voicemails

Leave Voicemail is on by default. hyzl auto-populates the voicemail message field for you. It generates that message from your call script and call details. You do not need to write anything to start. The campaign can leave voicemails the moment you launch it. If you do not want voicemails at all, turn Leave Voicemail off. The AI will hang up as soon as it detects voicemail.

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 does not fit, click Regenerate with AI to produce a new draft. The new draft replaces what was in the field. Repeat until you are happy with the message.

Write your own

Replace the field’s contents with whatever you would like the AI to leave. Whatever is in the field is read verbatim on every voicemail. The voicemail message does not support personalization variables, so the same message is left for every contact.
Revenue Recovery campaigns have an extra Callback Number field here. Unlike the voicemail message, that number is also added to the win-back text. If you leave the message as its auto-generated default, the voicemail updates itself when you later change your win-back discount. See Voicemail in Revenue Recovery.

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
