Paid for itself in seven days

The problem

Messages went out in bursts when there was time, follow-ups depended on memory, and replies sat in a personal inbox. No way to tell which conversations were still alive. Small enough to feel manageable, large enough to leak deals.

The obvious fix — a bulk sender — is also the fastest way to get a business number banned. That constraint shaped the build.

What I built

• Official WhatsApp Business API on approved templates, paced and warmed so the quality rating stays green.
• Timed follow-ups, so a silent contact is touched again on schedule rather than when someone remembers.
• Reply detection that pulls a live conversation out of the sequence and hands it to the human with context.
• Every send, delivery, read and reply written back to one record.

Why it worked

Nothing here is clever. It is consistency, made automatic, on a channel where people reply, run so the number survives past month two. Most outreach dies on the second and third touch — exactly the part a human stops doing.
