Say Goodbye to Manual Messaging: Introducing Smart Bulk SMS by SMSlenz.lk

In the fast-paced world of business, communication is everything. But let’s be honest: sending the same generic message to your entire contact list feels outdated, and manually personalizing hundreds of individual texts is a productivity killer.

Today, SMSlenz.lk is changing the game for Sri Lankan businesses. We are thrilled to announce our newest feature: Smart Bulk SMS.

🎯 What is Smart Bulk SMS?

Smart Bulk SMS allows you to send unique, personalized messages to hundreds or thousands of customers simultaneously using a simple CSV file.

Whether you need to send specific invoice reminders, unique appointment times, or custom order updates, Smart Bulk SMS handles the heavy lifting for you. It lets you:

  • Upload a CSV file
  • Include different messages for each recipient
  • Automatically create separate campaigns per message
  • Send everything instantly

🧾 How It Works (It’s as Easy as 1-2-3)

Simply prepare your CSV file, upload, and send.

  1. Prepare: Create a CSV file with two simple columns: phone and message.
  2. Upload: Drop your file into the Smart Bulk SMS dashboard.
  3. Send: Confirm your details and hit send. ✅

Example CSV Format: | phone | message | | :--- | :--- | | 94771234567 | Hello John your invoice is overdue. | | 94774567890 | Hi Sara your appointment is tomorrow. | | 94770111222 | Dear Mike your order is ready. |
