SendBroad

(01)Challenge

What was slowing things down

WhatsApp is where customers actually read their messages. But most businesses reach them through grey-route tools that put their number at risk, or through enterprise platforms priced and built for someone else.

BeforeContacts kept in spreadsheets → messages sent through unofficial tools or one by one → replies scattered across personal phones → no delivery or read data → per-message costs hard to predict.

(02)Solution

What we built

We built SendBroad end to end, from first sketch to live SaaS. A business connects its verified number through Meta, picks an audience, chooses an approved template and sends. Replies land in a shared team inbox, and developers get a REST API with webhooks for every delivery, read and reply.

AfterCSV import with validation and dedupe → segments → approved template with variables → scheduled, throttled send → live sent, delivered and read tracking → replies routed to a shared inbox.
