Doing it manually slows everything down
The point is not just sending more messages. It is losing less time, follow-up and clarity while you send them.
Without Sender Studio
Sending messages one by one eats up hours of your day.
Follow-up slows down and opportunities go cold.
Everything feels harder to manage and measure.

WhatsApp launched its own sender. Sender Studio is still easier to start.
Commercial broadcasts are WhatsApp's built-in way to send campaigns, but they are priced per message. Sender Studio lets you start with unlimited messages for free, then upgrade only when you want more speed, files, sequences or AI.
$0 to start
You can run your first Sender Studio campaigns without paying a subscription.
Unlimited messages
No extra Sender Studio fee per recipient or campaign.
Upgrade when you need more
Pro adds speed, attachments, sequences and AI follow-up.
