About
An independent tool for people who message their own contacts
WhatsApp Sender Tool is a Chrome extension that sends personalized one-to-one messages through WhatsApp Web, from your own number, at a human pace. It is built and maintained by a small independent team and is not affiliated with WhatsApp or Meta.
What we build
The product is a browser extension, not a cloud service. Your contact list stays in your browser, messages leave from your own WhatsApp account, and there is no server in the middle holding your conversations. That design decision shapes everything else: no account to create, no data to hand over, and a license you paste into the extension after paying.
The core is personalized bulk messaging, with CSV and Excel import, bulk voice notes and pacing controls that keep sending slow and irregular enough to look like a person typing.
What we will not build
We do not sell contact lists, scrape numbers, or provide any way to message people who never gave you their number. Those features are what get accounts restricted, and they are the reason a lot of similar tools disappear. If a request would turn the extension into a spam machine, the answer is no.
How we make money
One product, two prices: $9.99 per month or $69.99 per year. No free tier that harvests your data, no upsells, no ads. Full terms live on the terms page, refunds on the refund policy, and data handling in the privacy policy.
