Numbers and groups
Prepare recipient numbers using local or international formats, or use synced WhatsApp groups. Review the audience yourself; membership in a group does not itself establish consent to receive a separate campaign.
Delays and sending windows
A delay controls the gap between recipients. A schedule controls which days and hours sending is allowed. Set the timezone, save the window and press Start Campaign. A schedule does not wake a sleeping computer or run a closed browser.
Attachments and previews
Select supported attachments and review message content before the campaign. Test on an authorized recipient before a wider send. Browser and WhatsApp changes can affect supported behavior.
Read results correctly
Sent means the application confirmed the send, not guaranteed delivery. Delivery and read are last observed WhatsApp states. Missing read receipts do not prove a message is unread. There is no unlimited-send or anti-ban guarantee.
