WA Bulk Sender

About

WA Bulk Sender lets you send personalized bulk messages through WhatsApp Web directly from your browser.

FEATURES:

- CSV Contact Import: Upload your contact list as a CSV file. Just include a "phone" column and optionally a "name" column along with any custom fields.

- Personalized Templates: Write message templates using placeholders like {{name}}, {{phone}}, or any custom CSV column. Each contact receives a unique, personalized message.

- Campaign Management: Create, save, edit, pause, resume, and cancel campaigns. Track sent, failed, and remaining messages in real time.

- Scheduling: Schedule campaigns to run at a specific date and time. Set it and forget it.

- Smart Delivery: Messages are sent with randomized delays between each one to mimic natural human behavior. Configure the delay range to your preference.

- Progress Tracking: Monitor your campaign with a real-time progress dashboard showing delivery status for each contact.

- Dark Theme UI: Side panel interface that matches WhatsApp Web's native dark theme.

HOW IT WORKS:

1. Open WhatsApp Web (web.whatsapp.com) and make sure you're logged in.
2. Click the WA Bulk Sender icon to open the side panel.
3. Create a new campaign: give it a name, upload your CSV contacts, and write your message template.
4. Click "Start Campaign" and watch it send personalized messages one by one.

IMPORTANT NOTES:

- This extension requires WhatsApp Web to be open and logged in.
- Messages are sent one at a time with configurable delays to respect WhatsApp's usage patterns.
- The extension uses Chrome's debugger API to send trusted keyboard events that WhatsApp Web accepts, enabling fast message delivery without page reloads.
- Your data stays local. No contacts, messages, or personal data are ever sent to external servers. Everything is stored in your browser's local storage.
- This extension is not affiliated with WhatsApp or Meta.

PERMISSIONS EXPLAINED:

- Side Panel: Provides the campaign management UI alongside WhatsApp Web.
- Storage: Saves your campaigns, contacts, and settings locally in your browser.
- Active Tab & Scripting: Allows the extension to interact with the WhatsApp Web tab to search contacts, type messages, and click send.
- Debugger: Sends trusted keyboard events (like pressing Enter) to WhatsApp Web. WhatsApp Web ignores programmatic events from extensions for security, so the debugger API is used to send real keyboard inputs that WhatsApp accepts.
- Alarms: Handles campaign scheduling and keeps the extension alive during long-running campaigns.
