WbizTool Messaging - Self Hosted

Send WhatsApp campaigns from WhatsApp Web: contacts from Excel or CSV, personalised messages, images and files. Free, unlimited.

Send WhatsApp campaigns right from WhatsApp Web. Free and unlimited, no account needed. WbizTool adds a small panel to WhatsApp Web. Paste your numbers or upload a CSV or Excel file, write one message with personal details for each contact, attach images or documents, and send. Messages go out from your own WhatsApp, one after another, with a natural pause between them. HOW IT WORKS 1. Open WhatsApp Web and click the WbizTool icon in the left sidebar. 2. Add contacts: type or paste numbers, or upload a CSV or Excel file and pick the column with the phone numbers. 3. Write your message. Use variables like {{name}} or any column from your file, and WhatsApp formatting (bold, italic, strikethrough, monospace). A live preview shows exactly what each contact receives. 4. Attach files if you like: images, videos or documents up to 16 MB each. 5. Review and start. Follow the progress, pause, resume or stop at any time.

Connect it and this WhatsApp Web also sends your workspace's messages: API messages, dashboard campaigns, reminders and Google Sheets automations, while the tab is open. Those messages use your workspace's credits; campaigns you start from the extension stay free. PRIVACY Your contact lists, messages and campaigns stay in your browser. If you connect a WbizTool workspace, the extension only tells WbizTool that a campaign message was sent (no number, no text), and it receives the workspace messages it should send. You can log out at any time. GOOD TO KNOW • Keep the WhatsApp Web tab open while a campaign runs. • Only message people who expect to hear from you. Messaging strangers in bulk can get a WhatsApp account restricted; long pauses between messages help, but they don't make unwanted messages acceptable. • WbizTool isn't affiliated with or endorsed by WhatsApp or Meta.
