Free WhatsApp Sender by WA Web Sender is a browser extension that lets you send bulk WhatsApp messages straight from WhatsApp Web, without touching the official WhatsApp Business API. You install it in Chrome or Edge, open WhatsApp Web, then import your contact list from an Excel or CSV file, write one message, and use variables like name or company to personalize it for each recipient – you can also attach images, files, or videos and save the whole thing as a reusable template. Rather than blasting everyone at once, it sends in controlled batches with adjustable intervals, then gives you a progress report so you can export results and retry anything that failed.
It’s aimed at solo users and small teams doing sales follow-ups, customer updates, event reminders, or general outreach who want something quicker than manually messaging each contact but don’t want to deal with API setup or per-message fees.
