WhatsApp broadcasts get opened — often 70% or more, far above email. But that reach is a privilege, not a right. Send to people who did not opt in, or send messages they do not want, and your quality rating drops and your limits shrink.

This guide covers the four things that decide whether a broadcast performs: who you send to, what you send, when you send it, and what you measure afterwards.

None of it requires a developer — just discipline.

Start by being strict about consent. A contact should have actively agreed to hear from you on WhatsApp — a checkbox at checkout, a keyword reply, or a click-to-WhatsApp ad. Buying lists or importing everyone you have ever emailed is the fastest way to get blocked.

Once your list is clean, segment it. A broadcast that speaks to one clear group — recent buyers, cart abandoners, a single city — almost always beats one blast to everyone.
