      • Send SMS or voice

      SMS and voice are ready-made broadcast channels in Messaging: you create the send, write the text (SMS) or add an audio file (voice), choose the audience and send or schedule it. Unlike WhatsApp or Instagram, these channels go out through the platform's provider — there is no account to connect.

      Before you start

      • Role: the audience screens block guest and attendant (without the coordinator subrole); owner, admin and editor work normally.
      • Plan: SMS and voice start at Professional. Growth sends by Instagram, WhatsApp and email, but not by SMS or voice.
      • Credits: every send consumes channel credits. If the balance does not cover the audience, the send is refused with 402. All channels share the same monthly balance, so your reach depends on which you use.

      Steps

      1. Open Messaging and create a new broadcast on the SMS or voice channel.
      2. Give the send a name.
      3. Build the content:
        • SMS: write the text (160 characters — beyond that it is truncated to fit). Insert variables such as name and email to personalise it.
        • Voice: add one audio file, MP3 or WAV up to 5 MB — record it, upload it, or paste a publicly reachable link.
      4. Choose the audience — a list or a segment. The audience modes are covered in send a broadcast.
      5. (Optional) Schedule the date and time, adjust batch sending, or send a test to your own number.
      6. Send it, or save it as a draft for later.

      To fire SMS or voice automatically from an event or a stage, use an automation rather than a manual send.

      If it didn't work

      • The call does not go out, or the audio is discarded: the file must be MP3 or WAV up to 5 MB at a reachable link — the server checks the URL and rejects anything outside those rules.
      • The SMS arrived cut off: the text went past 160 characters and was truncated.
      • You cannot choose the audience: your role is guest, or attendant without coordinator. See no permission.
