Most WhatsApp bulk sender tools get your account flagged

Free plans on most tools send messages back-to-back with zero delay. WhatsApp's systems detect this pattern as bot activity and block the number — often permanently.

WABoost includes anti-ban protection free — no upgrade needed

Every message WABoost sends is followed by a randomised human-like delay of 5–15 seconds. WhatsApp cannot distinguish this from a real person typing and sending. This is the reason our users have sent over 10 million messages without a single reported ban.

Other tools lock this behind their paid plan. We include it in the free version because a tool that gets your account banned isn't useful to anyone.

Everything a WhatsApp bulk sender needs

Most bulk WhatsApp sender tools either require expensive API access or get your account flagged. WABoost solves both problems — for free.

Auto-name greeting — free, zero setup

WABoost reads the contact's name and automatically adds 'Hi Praveen', 'Hey Ravi', 'Hello Priya' to every message. No {name} tags. No column mapping. Every message looks individually typed.

Import from Excel, CSV, Google Sheets

Paste your contact list from any spreadsheet. WABoost reads the columns and maps them to message variables automatically.

Auto-greeting + random delay = undetectable

Auto-salutation makes every message unique. Random 5–15s delays mimic human typing speed. Combined, they're why WABoost users have sent 10M+ messages with zero account bans.

Delivery tracking

See which messages were sent, skipped, or failed in real time as your campaign runs.

Send to WhatsApp Labels & Groups

Pick any WhatsApp label — 'New Customers', 'Pending Payment', whatever you've set up — and send a bulk message to everyone in it. No CSV export needed. Also works for groups.

No API, no approval

Works directly inside WhatsApp Web. No Meta Business verification, no monthly fees, no developer needed.

One-click Chrome install

Add WABoost from the Chrome Web Store in 30 seconds. Open WhatsApp Web, click the extension, start sending.

Campaign Response Tracker

Ask contacts to reply 'YES' to your campaign. WABoost filters replies from that campaign only — so you see leads instantly without sifting through all your WhatsApp chats.
