About WbizTool Messaging - Self Hosted
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.
FEATURES
• Free and unlimited campaigns from the extension
• Contacts from pasted numbers, CSV or Excel (.xlsx)
• Country code added to local numbers automatically; duplicates and invalid numbers removed
• Personal messages with variables from any column
• Live WhatsApp-style preview for every contact
• Images, videos and documents, uploaded or from a link
• A random pause between messages (15–45 seconds by default, adjustable)
• Progress, sent / waiting / failed counts and an activity log while it runs
• Templates, saved campaigns, and exports of contacts, groups and group members
• 14 languages, following WhatsApp Web's language: English, Español, Français, Deutsch, Português, Italiano, Hinglish, 日本語, Русский, Türkçe, עברית, العربية, Bahasa Indonesia, Bahasa Melayu
• Light and dark theme, like WhatsApp Web
OPTIONAL: CONNECT YOUR WBIZTOOL WORKSPACE
Have a WbizTool account? 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.
