How does the WhatsApp Bulk Message Sender work without getting banned?

SIRF WhatsApp Bulk Sender uses official WhatsApp Web / app deep-links (wa.me) directly from your authenticated browser session. Because messages are confirmed and dispatched through your normal personal or business WhatsApp client rather than unauthorized scraping bots or headless scrapers, your account operates within WhatsApp's normal user flow.

What file format is required to import contacts?

You can upload any CSV or TXT file containing columns for Name, PhoneNumber (with international country code, e.g. +919876543210), and optional Tags. You can also download our free sample CSV template with one click.

Can I personalize messages for each recipient?

Yes. Use dynamic template tags including {name}, {phone}, {brand}, and {date}. The engine automatically substitutes each recipient's specific data in real time.

Are my phone numbers or customer contacts stored on any server?

No. The entire process runs 100% locally in your browser memory. No customer names, phone numbers, or message contents are ever sent to or stored on SIRF servers.

Best Practices for WhatsApp Marketing

To ensure optimal delivery, prevent spam reports, and cultivate long-term customer relationships, follow these golden rules:

• Permission First: Only message customers who have explicitly opted in or initiated business inquiries.

• Value-Packed Content: Offer actionable value, timely updates, or real savings rather than aggressive blast pitches.

• Clear Opt-Out: Allow recipients to reply with "STOP" if they prefer not to receive promotional updates.

• Verified Brand Signature: Always state your company or business name clearly in the opening greeting.

Frequently Asked Questions

Do I need to scan a QR code with third-party software?

No. SIRF WhatsApp Bulk Sender operates through your standard browser WhatsApp Web session. When you click send, it opens the official WhatsApp chat link without requiring unauthorized third-party extensions.

What is the recommended number of messages per batch?

For personal WhatsApp numbers, we recommend batches of 20 to 50 messages spaced 3 to 5 seconds apart. For WhatsApp Business accounts with established customer tenure, you can safely send higher volumes.

Can I send images or document attachments?

You can include image URLs or website links directly inside your message text, and WhatsApp automatically renders rich link previews. To send raw PDF or media files, paste the SIRF file link or drag the file into the opened WhatsApp chat.

Are my contacts saved across sessions?

Yes. Your contacts list, brand name, and custom message drafts are automatically saved in your browser's localStorage so you never lose progress.
