Use at your own risk

Sending bulk messages on WhatsApp violates their Terms of Service and can result in your number being temporarily or permanently banned.

WA Spark provides tools to reduce this risk but does not guarantee account safety. We are not liable for any bans, restrictions, or loss of access to your WhatsApp account.

Features

Everything You Need

50+ features to supercharge your WhatsApp workflow — from bulk messaging to deep analytics.

Bulk Messaging

Reach anyone on WhatsApp with three purpose-built sending modes. Personalize every message with dynamic variables, attach images and videos with captions, and import recipients from CSV files.

3 Modes
of sending
Send to Contacts

Bulk send to saved contacts, phone numbers, or imported CSV lists

Post to Groups

Broadcast the same message to multiple group chats simultaneously

DM Group Members

Extract members from any group and message them individually

Step-by-Step Wizard

Guided 4-step flow: recipients, compose, review, send

Media + Captions

Attach images, videos, and documents — send text as caption

Variable Personalization

Use {{name}}, {{firstname}}, {{phone}} for personal touch

Account Safety

Built-In Account Protection

WA Spark automatically mimics natural messaging patterns so your account stays safe. No warm-up guide needed - safety is built into every send.

Smart Delays

Randomized 6-15 second delays between each message. No two sends look the same - just like a real person typing.

Number Verification

Checks if numbers exist on WhatsApp before sending. No wasted messages, no red flags from invalid recipients.

Ban-Free
by design

Configurable Limits

Set your own min/max delay range. A red danger warning appears below 6 seconds to keep you in the safe zone.

Gradual Warm-Up

Start small with the free tier's daily limits. As your account builds trust, upgrade to Pro for unlimited sends.

Pro tip: New WhatsApp accounts should start with 10-20 messages per day for the first week, then gradually increase. WA Spark's free tier limits naturally enforce this warm-up pattern.

FAQs

Frequently Asked Questions

Is it really free?

Yes! The free tier includes 5 sends per day, 25 recipients per send, campaign tracking, analytics, and all privacy features. Pro removes all limits for $9.99/month.

Is bulk messaging safe for my WhatsApp account?

WA Spark uses randomized delays (6-15 seconds by default) between each send to mimic natural behavior. It also warns you when delays are set too low. Number verification checks if recipients exist before sending.

What about my privacy?

100% local processing. WA Spark has zero external servers, zero analytics, zero tracking. All your data stays in your browser and is never transmitted anywhere.

Can I send media attachments?

Yes! Send images, videos, and documents alongside your text messages. You can even send text as a caption on images and videos instead of a separate message.

What data can I analyze?

50+ metrics for any conversation: message volume, streaks, hourly/weekly activity charts, top words, top emojis, media breakdown, response behavior, who-talks-more analysis, and more. Export as styled HTML reports.

Does it work on mobile?

Desktop only. WA Spark is a Chrome extension that works with WhatsApp Web on Chrome, Edge, or Brave browsers.

Can I backup my data?

Yes! Use Import/Export to backup all your templates, lists, campaigns, and settings as a JSON file. Import on a new device or share templates with team members.
