Choose a delivery mode and send
Click Preview & Send and choose a delivery mode:
Send now - sends the broadcast immediately.
Schedule once - pick a date and time to send the message once.
You can also set the delay between messages — the number of seconds Periskope waits before sending to the next contact. A longer delay reduces the chance of hitting WhatsApp rate limits.
You can view all one-time scheduled broadcasts from Bulk messages > Scheduled messages > One time. Each entry shows the scheduled send time, message preview, and recipient count.To set up recurring broadcasts that run automatically, see Repeating Bulk Messages.For information on message credits, see Broadcast Credits.
