Bulk WhatsApp Sender for Windows
TechBotMaster WhatsApp Sender is a Windows program that sends your WhatsApp messages to your own contact list for you: text, photos, videos and documents, with each person's name in the message, on a schedule you choose.
What you can do with it
- Send text, photos, videos and files in one campaign, with a caption.
- Put a name in every message. Write
Hi {name}, our new batch starts on Mondayand every contact sees their own name (and city, or any column from your Excel file). - Import from Excel or CSV. The first row can name your columns, so
{customer_name}works too. - Clean your list in one click. Numbers are fixed (country code, spaces, zeros), duplicates and wrong numbers are removed, and people who asked you to stop are skipped.
- Schedule and repeat. Start tomorrow at 10:00, or every Monday.
- See who answered. In Background mode a reply inbox shows the answers to your campaign, lets you label the interested ones and reply from the app, with optional automatic replies.
- Reports. Every run is kept with who got it and who did not. Download it as CSV and retry the failed ones with one click.
- A daily limit and random gaps between messages keep your activity natural.
Two ways to send
Background mode (recommended). You link your phone once by scanning a QR code, like linking WhatsApp Web. The app then sends quietly in the background. You do not need WhatsApp Desktop and your mouse and keyboard stay free.
WhatsApp Desktop mode. The app drives your WhatsApp Desktop window like a person would. It needs WhatsApp Desktop to stay open and the mouse and keyboard are busy while it sends.
Your contacts stay on your computer
The program runs on your own PC. Your contacts, messages and files are not uploaded to our server. Our server only checks your license key. There are no per-message fees: you pay for the license, not for each message.
Who it is for
Shops, coaching classes, real estate agents, gyms and clinics, agencies and freelancers who message their own customers. See how it works for coaching classes, real estate agents and shops.
An honest word about risk
WhatsApp's rules do not allow automated or bulk messaging, and WhatsApp can restrict or ban a number. Delays, batches and daily limits lower the risk but cannot remove it. Use a number you can afford to lose, send only to people who know you, and start with a few messages. Read how to send bulk WhatsApp messages more safely. If you need a fully official route, compare it with the WhatsApp Business API.
