WhatSender Pro

WhatSender Pro 4.0 is a professional Chrome extension that works on any computer — Windows, macOS, and Linux — without downloading any additional software. Just install it in Google Chrome, scan the WhatsApp Web QR code once, and you're ready to send bulk messages, manage contacts, and automate your WhatsApp workflow entirely from the browser.

Unlike the desktop WSTool software, the Chrome extension version requires no installation beyond the extension itself, making it ideal for Mac and Linux users. It comes with 5 dedicated tabs for single messaging, bulk messaging, contacts management, group messaging, and settings.

📱 5 Powerful Tabs

• Single Message — send individual messages to any number, even unsaved contacts, with optional image or PDF attachment.
• Bulk Message — send the same (or personalised) message to a long list of numbers, imported via CSV or copied from your contacts.
• Contacts Manager — auto-load your WhatsApp contacts, search, filter, select multiple, and export to CSV.
• Groups Manager — send messages to multiple WhatsApp groups at once; shows group name, avatar and member count.
• Settings & License — toggle dark/light theme, view statistics, and activate your PRO license.

📋 How to Install & Get Started

1. Install WhatSender Pro from the Chrome Web Store — click "Add to Chrome".
2. After installation, WhatsApp Web opens automatically. Scan the QR code to connect your WhatsApp account:
   • Android: WhatsApp → Menu (⋮) → Linked Devices → Link a Device
   • iPhone: WhatsApp → Settings → Linked Devices → Link a Device
3. Click the WhatSender Pro icon in your Chrome toolbar to open the main panel.
4. Choose your tab (Single Message, Bulk Message, Contacts, Groups) and start messaging.

📨 Bulk Messaging & Personalisation

Enter one phone number per line (with international country code), or upload a CSV file with numbers and up to 2 custom variables. Use @valueOne and @valueTwo in your message to personalise each one automatically. Set the delay between messages (default 4 seconds, recommended 4–8 seconds) and optionally attach a JPG, PNG, or PDF file.
