WatSender

Send smarter, not spammier - the all-in-one WhatsApp bulk sender with built-in number warming, lead extractors, and auto-reply.

WatSender is a modern .NET 8 Windows desktop app that turns WhatsApp Web into a full bulk-marketing workstation. Manage unlimited accounts in isolated WebView2 sessions, validate numbers, personalize messages with variables and rich attachments (images, captions, contacts, locations, polls and interactive buttons), then schedule campaigns to send on autopilot. Built-in account warming with randomized delays, a keyword auto-reply bot, and lead extractors (Google Maps, business, email, social and group scrapers) make it a complete prospect-to-conversation pipeline rather than just a blaster.

$59 USD, one-time payment, lifetime license.
