On the PC and the phone
WhatsApp installed and online
You only link your WhatsApp once — it remembers you after that.
Download the installer above and double-click it. Windows may show a blue "Windows protected your PC" box — click More info → Run anyway.
Open the app and wait for the QR code. On your phone go to WhatsApp → Settings → Linked Devices → Link a device and scan it. The badge turns to Connected ✓.
Load your WhatsApp contacts (or upload a CSV, or paste numbers), type your message, attach files, and press send. A live progress bar shows every recipient as it goes out.
Load your saved WhatsApp contacts, upload a CSV, or paste a list of numbers.
Up to 10 attachments per campaign, 64 MB each. Add them all at once or one at a time.
A random 30–60 second gap between messages, so sending doesn't look mechanical.
Every message is confirmed with WhatsApp's servers. "Failed" means it truly didn't go out.
Watch sent and failed counts update per recipient, with a line for each one.
No cloud account and no middleman. Messages go through your own WhatsApp.
Keep the app open while a campaign runs. Anyone not yet reached won't get the message if you close it early. The app warns you if you try.
Sending takes time on purpose. The 30–60 second gaps are what keep your number safe:
| Recipients | Roughly how long |
|---|---|
| 20 people | 10–20 minutes |
| 50 people | 25–50 minutes |
| 100 people | 50–100 minutes |
Click More info, then Run anyway. Windows shows this for any installer it hasn't seen from a paid certificate authority yet. It is safe to continue.
Install Chrome from google.com/chrome and open the app again. Microsoft Edge works too, and comes with Windows.
No — only the first time. The app saves the link and reconnects on its own. You'd only rescan if you unlink the device from your phone.
Check your internet, then close the app fully and reopen it. If your antivirus or firewall is blocking it, allow Bulk WhatsApp Sender.
Yes. Keep browsing and use WhatsApp on your phone as normal — just don't close the app window or let the PC sleep until the progress bar finishes.
That number isn't registered on WhatsApp, or the country code is missing. Numbers need the full country code, e.g. 919876543210.
Press Windows + R, paste %APPDATA%\BulkWhatsAppSender and press Enter. Send us the log.txt file from that folder.
Message people who expect to hear from you. Recipients blocking or reporting you is the fastest way to get a WhatsApp number restricted — more than volume alone.
Use a separate number rather than your main business line, vary your message wording, and build up gradually on a new number.
