Everything you need

Built for real WhatsApp campaigns

Every feature designed around two goals: reach more people safely and save you time.

All plans

Smart Contact Import

Paste numbers, upload CSV/Excel, or use saved groups. Auto-validates country codes and removes duplicates instantly.

All plans

Personalised Messages

Use {{name}}, {{phone}}, {{city}} or any custom variable. Live preview shows each contact's exact personalised message.

Built-in

Smart Sending Controls

Random delays between messages, automatic batch pausing, and natural typing patterns help you pace campaigns responsibly.

Real-time

Live Campaign Monitor

Animated progress ring, per-message status feed, batch countdown timer, and full pause / resume / stop controls.

Analytics

Campaign Reports

Full history with sent / failed counts, delivery rate, and duration. Export the complete delivery log as CSV.

Secure

Security & Privacy

Saved contact groups are AES-256-GCM encrypted on your device before upload. We never sell your data or use ad trackers.

v0.7

Per-Recipient Attachments

Put all files in one folder and name each by the recipient's phone number. Each contact automatically receives their own file — images, PDFs, or videos up to 25 MB.

v0.7

Number Validation

The extension checks every contact against WhatsApp before sending — live progress ring per number. Remove all invalid numbers in one click to protect your account.

PRO

Wami AI Message Rewrite

One click rewrites your message in any tone — Friendly, Professional, Urgent, Casual, or Formal. Wami types the rewritten message character by character so it feels natural.

v0.9

Message Spintax

Write {Hi|Hello|Hey} {name} and every recipient gets a different version. A live counter shows how many unique combinations your message generates — drastically reduces spam detection.

Built-in

Anti-Ban Protection

Human-like typing simulation, random inter-message delays, automatic rest breaks every 15–22 messages, and invisible fingerprint — WhatsApp cannot distinguish your sends from a real person.

FAQ

Frequently asked questions

Still have questions? Email us anytime

Will my WhatsApp account get banned?
WA Bulk Messenger uses randomised delays (2–12 s), automatic batch pausing, and message personalisation — all designed to mimic natural human behaviour. WhatsApp's own ToS discourages bulk messaging. Use responsibly: only message opted-in contacts, keep volumes reasonable, and always personalise your messages.

Do I need WhatsApp Business or an API key?
No. WA Bulk Messenger works directly on WhatsApp Web — no Business API, no paid API key, no special account type required. If you can open WhatsApp Web, you can use it.

Is my contact data safe?
We take security seriously: data is sent over HTTPS, passwords are bcrypt-hashed, and saved contact groups are AES-256-GCM encrypted on your device before upload (we cannot read them). Campaign recipients and message content are stored on our servers so your campaigns work across devices. We never sell your data or use ad trackers, and you can delete your data at any time. See our Privacy Policy for full details.

What's the difference between FREE and PRO?
FREE: 50 messages/month, 20/batch, longer delays, 5 uses/month for advanced features. PRO (₹499/month): 5,000 messages/month, 100/batch, shorter delays, unlimited advanced features, plus AI message rewriting in 3 tones.
vs Competitor

How does WA Bulk Messenger compare to WASender?
WASender charges ₹1,199/month — 2.4× our PRO price of just ₹499/month. But it's not just about cost: WASender has no AI message rewrite, no encrypted contact groups, no live campaign monitor ring, and no follow-up sequences. You pay 2.4× more and get significantly fewer features. Our FREE plan alone is already more capable than WASender's entry tier.
vs Competitor

How does WA Bulk Messenger compare to WAWebSender?
WAWebSender charges ~$14.99/month (≈ ₹1,250) — that's 2.5× the cost of our PRO plan. More importantly, WAWebSender does not include smart sending delays or encrypted contact groups, which support responsible, compliant bulk messaging. WA Bulk Messenger installs in 10 seconds, works instantly on WhatsApp Web, costs ₹499/month PRO, and includes every feature WAWebSender lacks.

Why is WA Bulk Messenger cheaper than all competitors?
Messages are delivered through your own WhatsApp Web session rather than through paid WhatsApp Business API infrastructure, which keeps our costs low — and we pass the savings on to you. You get the same core features as pricier competitors at a fraction of the price.

Can I send images, videos, or PDFs?
Yes — up to 25 MB per attachment on any plan. FREE plan includes 5 media campaigns per month. PRO plan: unlimited media campaigns.

Can I schedule campaigns to send later?
Yes — available on the PRO plan. Set a date and time, then choose once, daily, weekly, or monthly recurrence. Campaigns run automatically when WhatsApp Web is open.

What happens if I close the browser mid-campaign?
The campaign pauses immediately because it requires WhatsApp Web to be open. Reopen the extension within 4 hours and you'll be offered the option to resume from exactly where you left off.

Does it work on Mac and Windows?
Yes — it works on any operating system that runs Google Chrome: Windows, macOS, and Linux.
