WhatsBulk – Bulk WhatsApp Messaging
WhatsBulk – Bulk WhatsApp Messaging Tool (Concept Overview)
It looks like “WhatsBulk” isn't a widely recognized brand name—but there are multiple tools that offer very similar functionality under other names (such as Whatso, WhatsBulkApp, WasendBulk, WhatsAuto, and others). These are commonly used for bulk WhatsApp messaging. If “WhatsBulk” refers to one of these or a similar type of tool, here’s a detailed overview:
WhatsBulk (or similar platforms like Whatso, WasendBulk, WhatsBulkApp, etc.) are third-party tools designed to send bulk WhatsApp messages to a large number of users for marketing, campaigning, customer engagement, and notifications.
These tools work outside of the official WhatsApp Business API, meaning they simulate human behavior using web automation (via WhatsApp Web or mobile emulation), but this comes with risks of bans and compliance issues if not used responsibly.
- Upload contact lists, send bulk broadcasts with images, attachments, videos.
- Offers campaign analytics and filtering tools.
- Provides multi-WhatsApp-number support and delays to reduce ban risk.
- Web-based or Chrome-extension tool — no installation needed.
- Supports multimedia attachments, dynamic send timers, and subscriber templates.
- Auto country-detection for personalization and background message delivery.
- Chrome-extension that works via WhatsApp Web.
- Supports personalized placeholders, Excel uploads, scheduling, reports, and attachments.
- Pro version includes advanced analytics and batching features.
- Windows-only software (one license per PC).
- Includes features like group member extraction, Google Maps scraper, auto-responder bots, and dynamic templates.
- Account Ban Risk: Numerous Reddit user reports confirm that bulk messaging without a compliant API frequently leads to temporary or permanent bans—even at low volumes (e.g. 50–120 messages at once)
- WhatsApp Business API Compliance: Tools based on the official Business API (like Wati, Sendwo, Bulking, etc.) offer safer, scalable campaigns that abide by WhatsApp’s rules. These are recommended for high-volume or professional use cases
- Spam Avoidance: Ensure all recipients opt-in explicitly to receive messages. Warm up numbers gradually (e.g. 30–50/day initially), use personalized messages, and engage in genuine two-way chat activity—not only mass broadcasting
