About SL Sender
1. Send WhatsApp Messages Automatically
Description: Enables fully automated message sending to a specified contact list via WhatsApp Web without manual intervention.
Benefit: Send messages to hundreds of contacts simultaneously with a single click, saving time and operational effort.
2. Send Pictures, Videos with Messages
Description: Attach media files—such as images (JPG/PNG), videos (MP4), or documents (PDF)—along with your text messages.
Benefit: Ideal for sending promotional banners, product catalogs, brochures, or explainer videos to boost engagement.
3. Message Customization
Description: Personalize each message using dynamic variables (e.g., Name, Order ID, Due Amount).
Example:
"Hi [Name], your order [Order_ID] is confirmed. Total amount: Rs. [Amount]."
Benefit: Creates a professional, tailor-made communication experience for every customer.
4. Setting the Message Sending Interval
Description: Set a dynamic time delay (e.g., 5 to 15 seconds) between consecutive messages.
Benefit: Simulates natural human typing behavior to protect your account from being banned by WhatsApp’s anti-spam algorithms.
5. Batching
Description: Divide large contact lists into smaller batches (e.g., send 20 messages, pause for 5 minutes, then resume).
Benefit: Prevents bulk traffic spikes and ensures stable, reliable delivery without triggering rate limits.
6. Message Templates
Description: Save frequently used messages as reusable templates for quick deployment.
Benefit: Saves time on repetitive typing and maintains consistent marketing and customer service messaging.
7. Enter Numbers Through an Excel File
Description: Import contacts and personalized data directly from Excel files (.xlsx / .csv).
