When configuring campaigns, you can choose to send messages that will be left as voicemails for the recipients. These voice messages can be a message that you record, or a message that you type. Typed messages are converted to voicemails using text-to-speech technology. Review Configuring Voice Messages to learn more.

The software delivers messages to the Delivery Address you configure. For messages to be delivered, the delivery phone number needs to include a country code. You can add additional phone number options to your contacts by editing the Contact Type from the Settings menu. Once a new phone number type is added, you can use the import feature from the Contacts view to populate phone numbers as needed.
When sending voice messages, typed messages are converted to audio. In this scenario, consider the following rules:
