Free Bulk WhatsApp SenderChrome Extension
Boost your WhatsApp marketing with smart automation. Every message gets an auto-personalised greeting — "Hi Praveen", "Hey Ravi" — with zero setup. Import from Excel, CSV, or Google Sheets. No API, no coding, no monthly fees.
Works seamlessly with tools your business already uses
Most tools get your account flagged. WABoost doesn't.
WABoost automatically adds a personalised greeting to every message — "Hi Praveen", "Hey Ravi", "Hello Priya" — making each one look individually typed. Combined with random human-like delays between messages, WhatsApp cannot detect your campaign as bulk sending. Both features are free and on by default.
Auto-Greeting + Smart Delay — Free
Both on by default, zero setup
Each message starts with a different greeting ("Hi", "Hey", "Hello") + the contact's name — automatically. Add randomized delays and WhatsApp's algorithm cannot distinguish your campaign from a real person personally messaging each contact.

Join thousands of satisfied customers who have transformed their WhatsApp marketing with WABoost's powerful automation tools.
"The auto-name greeting is the reason I switched. Every message goes out as "Hi <name>" with zero setup, so it never looks like bulk. We messaged 2,000 customers about our sale and not a single account warning."
"I import my customer list straight from Excel and send festival offers in minutes. What used to take me a full day of copy-pasting now takes ten minutes. Genuinely the most useful extension I've installed."
"I send property updates to hundreds of leads every week. The campaign response tracker shows me exactly who replied to that campaign — I'm not scrolling through every chat anymore. Huge time saver."
"The random delay between messages kept our number safe even on big sends. We've sent over 30,000 order updates through WABoost with no bans. The free plan already does more than tools we used to pay for."
"Being able to download group lists and contacts by label to CSV is something competitors charge separately for. WABoost bundles it free, and the delivery reports let me prove ROI to clients every month."
"Our team follows up with new leads the same hour they come in. Since we started using WABoost the reply rate on our outreach has roughly doubled. Setup took two minutes — no API, no developer."

Frequently Asked Questions
Everything you need to know about sending bulk WhatsApp messages safely with WABoost.
Is it safe to send bulk WhatsApp messages?
Yes, when done correctly. WABoost is designed for safety with features like randomized sending delays and adherence to WhatsApp's guidelines. We recommend starting with smaller batches and messaging contacts who have opted-in to avoid being flagged as spam.
Can my WhatsApp account get banned for bulk messaging?
There is always a risk if WhatsApp's policies are violated. However, WABoost minimizes this risk by simulating human-like behavior. To stay safe, always send valuable content to contacts who expect to hear from you and avoid sending unsolicited messages.
Do I need the WhatsApp Business API to use WABoost?
No, you do not need the official WhatsApp Business API. WABoost works by securely automating your existing WhatsApp Web session, making it an accessible and cost-effective solution for small to medium-sized businesses.
How can I personalize messages in a bulk campaign?
WABoost allows you to personalize messages using variables. You can upload a CSV or Excel file with columns for names, order numbers, or any custom field, and use placeholders like {name} in your message template for customized outreach at scale.
What is the difference between broadcast lists and a bulk messaging extension?
WhatsApp's native broadcast feature limits you to 256 contacts who must have your number saved. A bulk messaging extension like WABoost bypasses this limit, allowing you to send messages to thousands of contacts, saved or unsaved, directly from a spreadsheet.
How do I import my contacts into WABoost?
You can easily import contacts by uploading a CSV or Excel file. Simply prepare a spreadsheet with columns for phone numbers and names, and WABoost will import them into your contact list for your campaign, ensuring a seamless setup.
Can I download my full WhatsApp group list?
Yes — WABoost can export the complete list of WhatsApp groups you're a member of to a CSV or Excel file in one click. The export includes group name, member count, and join date. Many tools sell this as a standalone paid product; WABoost includes it free.
Can I create WhatsApp groups in bulk from an Excel sheet?
Yes. Upload an Excel file with a column for group names and additional columns for member phone numbers (with country code). WABoost will automatically create every WhatsApp group and add all members — no more manually adding people one by one. This feature is free in the WABoost Chrome extension.
Can WABoost back up my WhatsApp chats?
Yes — WABoost can back up individual conversations or full group chat histories and export them to a file for records, compliance, or migration. All processing happens locally inside your browser; nothing is uploaded to our servers.
