I've watched a dozen coaches try to sell through WhatsApp and most of them make the same mistake: they treat it like email.

WhatsApp isn't a broadcast channel, it's a conversation channel. Open rates sit around 90%+ because people actually read their DMs — but that also means a generic blast reads as spam instantly. The coaches who win split their list into segments (cold lead, warm lead, active student) and send something that feels 1:1 even when it's automated.

The second mistake: no follow-up sequence. A lead goes quiet after the first message and nobody nudges them again. A simple 3-message drip (value → objection-handling → soft CTA) spread over 5 days recovers a shocking number of "dead" leads.

Built WhatsGrow around exactly this — broadcast segmentation + drip automation for people selling coaching/courses through chat. If you're doing WhatsApp outreach manually right now, happy to trade notes on what's working.
